An Introduction to Smart Grid

A smart grid is an electrical grid that uses information and communications technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.

Smart grids are now being used in electricity networks, from the power plants all the way to the consumers of electricity in homes and businesses. The “grid” amounts to the networks that carry electricity from the plants where it is generated to consumers. The grid includes wires, substations, transformers, switches etc. The major benefits are significant improvement in energy efficiency on the electricity grid as well as in the energy users’ homes and offices.

What is Smart Grid

In a typical smart grid, central management center controls all the units connected to it making sure to operate them at the highest efficiencies. The central management center does not only assist in better energy management inside the facility but also it helps in reducing the electrical consumption during peak times. This reduction is reflected as huge energy savings.

A smart grid also facilitates switch from conventional energy to renewable energy. In case of having a source of renewable energy in the facility, the grid allows an easy access to integrate it into the grid. Smart grid permits greater penetration of highly variable renewable sources of energy, such as wind power and solar energy.

Smart grid is a new gateway to a green future. It not only provides better energy benefits but also opens up new avenues of employment for youngsters. For example, conversion of normal operating units into smart ones capable of connecting to the smart grid is full of new and exciting opportunities. The global market for smart instruments is trending up with out-of-the-box ideas and innovations from young energetic minds.  

Smart Grid Prospects in the Middle East

The Middle East electricity market is growing at an accelerating rate due to higher consumption rates in the private, commercial and industrial sectors. This results in the need for a successful implementation strategy that can bridge the gap between the current supply and increasing demand. A smart grid network makes for the ideal bridge where the goals of modernization can meet those of a reliable public infrastructure.

Regional countries such as UAE, Saudi Arabia and Jordan are moving ahead smart meter rollouts. The high incomes in those countries, high electricity consumption, and small populations will drive smart meter deployments in the medium-term. The technologies used and lessons learned in these deployments will then be diffused throughout the region.

Smart grid offers an excellent opportunity to modernize Middle East power infrastructure, lay the foundation for energy management, provide new employment opportunities and ultimately reduce region’s dependence on fossil fuels. The Middle East region has the highest per capita carbon footprint in the world which can be offset by deployment of smart energy systems.

In the last few years, the number of events, conferences and meetings focused on smart grid and smart energy has sky-rocketed in the Middle East. The growing amount of attention being paid to this area reflects an increased sense of urgency to meet the energy requirements of fast-growing population and sustain the rapid industrial growth across the region.

District Cooling Perspectives for the Middle East

District cooling produces chilled water in a centralized location for distribution to buildings like offices and factories through a network of insulated underground pipes. The chilled water travels to different buildings, where the water circulates through refrigeration coils or uses absorption technology to enter the air-conditioning system. During winter, the source for the cooling can often be sea water, so it is a cheaper resource than using electricity to run compressors for cooling.

What is District Cooling

District cooling provides effective control over internal temperature of a building, requires less maintenance than a standalone air-conditioning system, consumes lesser space and reduces noise pollution. The effect of district cooling systems on the environment is minimal because of the reduction in carbon dioxide emissions, use of eco-friendly refrigerants and implementation of rigorous health and safety standards.

The Helsinki district cooling system in Finland uses waste heat from CHP power generation units to run absorption refrigerators for cooling during summer time, greatly reducing electricity usage. In winter time, cooling is achieved more directly using sea water. The adoption of district cooling is estimated to reduce the consumption of electricity for cooling purposes by as much as 90 percent. The idea is now being adopted in other Finnish cities.

The use of district cooling is also growing rapidly in Sweden and in a similar way. District cooling is very widespread in Stockholm, the capital of Sweden. In fact, approx. 7 million square meters of commercial space in Stockholm is connected to the district cooling grid. The Stockholm district cooling grid currently consists of different systems with capacities ranging from 3 MW to 228 MW. The district cooling network in Stockholm is currently 76 kilometers long.

District Cooling Prospects in the Middle East

There is tremendous potential for the utilization of district cooling systems in the Middle East. The constant year-round heat coupled with expensive glass exteriors for hotel, airports and offices etc result in very high indoor temperatures. The combination of distributed generation of power and utilization of waste heat can provide a sustainable solution to meet the high demand for refrigeration in the region. District cooling systems can provide cooling solutions to commercial buildings, hotels, apartment blocks, shopping malls etc.

The world’s largest district cooling plant, Integrated District Cooling Plant (IDCP), was installed in The Pearl-Qatar in 2010. IDCP will service more than 80 apartment towers, beachfront villas, townhouses, shopping complexes, offices, schools and hotels throughout the Island, ultimately supplying more than 130,000 tons of refrigeration to the Island’s estimated 50,000 residents.

Despite paramount importance of air conditioning in Middle East countries, regional governments have failed to incorporate it in policy and planning which has lead to the evolution of an unregulated market for cooling systems.  Most of the cooling methods employed nowadays are based on traditional window units or central air cooling systems where consume copious amount of power and also damage the environment.

District cooling has the potential to provide a viable solution to meet air conditioning requirements in the Middle East. Low energy requirement, peak saving potential, eco-friendliness and cost-effectiveness are major hallmarks of district cooling networks. District cooling can play a vital role in fostering sustainable development in Middle East nations. Apart from providing cooling needs, district cooling can reduce the need for new power plants, slash fossil fuel requirements and substantially reduce greenhouse gas emissions from the region.

Peak Oil: Perspectives for Saudi Arabia

PeakOil-SaudiArabiaThe term ‘peak oil’ is ominous to the Middle East, as most of the countries in the region are heavily dependent on oil and natural gas for industrial, economic and social development. Petroleum is considered one of the world’s most important sources of energy generation, after uranium, of course. Many other substances have been tested in order to be used as alternatives to petroleum, but none have hitherto been successful. Scientific research illustrates how the world is facing catastrophe if it doesn’t find an alternative to oil, as it is currently impossible for the global economy to grow without sufficient amounts of energy which are adapted to the demands of this growth. There is more discussion now than ever before about how the world is definitely starting to approach a stage of peak oil.

What is Peak Oil

Peak oil is a termed coined by the renowned American geologist King Hubbert in the fifties. He managed to predict an oil peak in several regions in America which would occur in the seventies; and exactly what this scientist predicted did in fact happen. For when oil extraction reaches extreme levels it begins to decline and gradually ends. Oil is considered a finite resource, or one which isn’t renewed as it is used up.

This theory confirms that global oil production has reached its peak today and has started declining inexorably now that 50% of the world’s oil reserves have been consumed. This proves that oil could be on the brink of depletion if clear and serious plans are not put in place to guide consumption and therefore encourage using provisional reserves in the best way. However, this theory is not accepted by many or by those who continue to focus on how large the earth’s oil reserves are, and how they only need investment so that they can be drilled.

Peak Oil Scenario for Saudi Arabia

Saudi Arabia is considered one of the largest global oil exporters and the only one able to regulate and stabilise the global oil market, thanks to its reserve stocks. These reserves are calculated to be at 265.4 billion barrels, or what is enough to last, at the current level of production, for more than 72 years. According to ARAMCO reports, there are around a trillion barrels that will be discovered in the future and will satisfy global demands, despite current consumption, for one whole century.

 Saudi Arabia is currently focussing its efforts on drilling and extracting natural gas, as it doesn’t import it but depends on domestic production. Alongside this, the Saudi Kingdom is currently making huge investments in nuclear energy and solar power.

But can natural gas and renewable energy be relied upon as alternatives to oil in order to satisfy Saudi Arabia’s domestic needs, which are rapidly growing each day? According to a recent report by America’s Energy Information Administration (EIA), Saudi Arabia is the largest oil-consuming nation in the Middle East. Saudi Arabia consumed 2.9 million barrels per day of oil in 2013, almost double the consumption in 2000, because of strong industrial growth and subsidised prices. One important contributor to Saudi oil demand is the direct crude oil burn for power generation. There is not just enough fuel oil and natural gas to meet the demand and hence the resorting to crude oil.

Has peak oil really arrived? If not today, then when? And how will it look, especially for countries totally dependent on oil? Will its consequences be different for both developed and under-developed nations?  Given that global demand for oil will only grow to exceed 100 million barrels a day after 2020, according to the most extreme estimates, I believe that the time may have come for the Kingdom of Saudi Arabia to start planning for what follows the oil era.

Despite looming threat of peak oil, power generation capacity in KSA is expected to rise from current level of 58GW to 120GW by 2032, however Saudi Arabia cannot afford to burn rising crude oil volumes for power generation. In spite of the fifth largest natural gas reserves in the world, it does not produce sufficient gas for power generation and for its vast petrochemical industry. The only solution at this point of time is transition to low-carbon economy whereby Saudi Arabia make use of its massive solar energy potential, implement effective measures for improving energy efficiency in the industrial sector and remove huge energy subsidies for industrial and domestic users.

 

Note: The article has been translated from Arabic by Katie Holland who graduated from Durham University in 2015 with a degree in Arabic and French, having also studied Persian. Currently working in London, she hopes to develop a career that uses her knowledge of Arabic and the Middle East, alongside pursuing her various interests in the arts.

Energy Efficiency Perspectives for UAE

With Abu Dhabi alone on track to generate more than 10,000 megawatts of electricity for the first time, discussion about improving energy efficiency in the United Arab Emirates is taking on a more critical tone. Daytime energy use in the hot summer months is still experiencing rampant year-on-year growth, with peak demand this year growing by 12 per cent. Lying at the heart of these consumption levels is the need for air conditioning, which accounts for about half of total electricity demand.

Business and Government Action

At the commercial level, considerable steps are being taken to reduce the Emirate’s carbon footprint. A building insulation program in Dubai has resulted in claims that all buildings there have become twice as energy efficient since completion of the program. Further steps are also underway in other ecological areas such as water efficiency and waste management with the intention of ensuring the green credentials of every building meet international environmental standards and expectations.

At the official level the Emirates’ Authority for Standardization and Metrology continues to implement its Energy Efficiency Standardization and Labelling (EESL) program. This introduced specific efficiency and labelling requirements for non-ducted room air-conditioners in 2011.

These measures were joined this year by requirements under the same program for many other household electrical goods including lamps, washing machines and refrigerating appliances. The labelling requirements under this program will become mandatory by 2013 enabling consumers to see which machines are the most efficient and make sound environmental choices that will also save them money on running costs. The EESL programme will be further extended in 2013 to include ducted air-conditioners and chillers.

The UAE’s oil and gas sector also is recognising the importance of the energy efficiency agenda. It might seem counterintuitive that a sector with oil reserves of about 97 billion barrels and natural gas reserves of six trillion cubic meters should be thinking about how to save energy. The issue is that these reserves, despite their size, are not finite and that oil for export produces greater revenue generation than oil for the domestic market. It is, therefore, in the oil and gas sector’s interest to work with those trying to drive down domestic consumption, as it will maximise the sector’s longer term sustainability.  

The Emirates Energy Award was launched in 2007 to recognize the best implemented practices in energy conservation and management that showcase innovative, cost effective and replicable energy efficiency measures. Such acknowledged practices should manifest a sound impact on the Gulf region to stir energy awareness on a broad level and across the different facets of society.

Significance of Behavioural Change

As much as formal initiatives and programmes have their place in the battle for a more energy efficient UAE, there also needs to be a general shift in culture by the public. Improving public perception of green issues and encouraging behaviours that support energy efficiency can contribute significantly towards the overall goal. As fuel prices increase in the domestic market, the UAE’s citizens are already adding more weight to fuel efficiency when considering what cars they will buy.

SUVs and 4x4s might still be the biggest sellers but household budgets are becoming increasingly stretched and many ordinary citizens are looking for smaller more efficient cars. Perhaps for the first time, the entire running costs of cars are being considered and the UAE’s car dealers and their suppliers are looking to accommodate this change in their customers’ attitudes. This trend is so significant that some car dealerships are seeing large year-on-year increases in sales of their smaller, more efficient models.

Car rental companies are seeing this trend also and in Dubai, at least one is making hiring a car with green credentials more appealing to a wider cross-section of the public – offering everything from the more familiar Chevrolet Volts and Nissan Leafs to the most exotic hybrid and fully electric cars available to hire or lease.

Capitalising on these trends makes both environmental and business sense but economic drivers cannot alone be left to change public behaviour. There are really simple measures that government and business should be encouraging people to take. Some may argue that switching-off computers, lights and air-conditioning at the end of the working day may save energy but is not sufficiently worthwhile promoting – voluntary measures of this sort will not impact on overall energy trends.

There is evidence however that if these behaviours are added to measures like installing energy efficient lighting, lowering thermostats and optimising EESL five-star rated air-conditioners, the energy savings really do become significant – potentially halving a building’s energy consumption.

Conserving energy may not yet be a way of life in the UAE but the rapid changes being seen there are an indicator of what is to come. Formal energy efficiency programs and voluntary measures combined will help the UAE maintain its economic strength in the region and because of this it is one agenda that will not be going away.

Energy Efficiency in Saudi Cement Industry

Saudi Arabia is the largest construction market in the Middle East, with large development projects under way and many more in the planning stage. The cement industry in the country is evolving rapidly and is expected to reach annual clinker production of 70 million tonnes in 2013 from current figure of 60 million tonnes per year. The cement industry is one of the highest energy-intensive industries in the world, with fuel and energy costs typically representing 30-40% of total production costs. On an average, the specific electrical energy consumption typically ranges between 90 and 130 kWh per tonne of cement. Keeping in view the huge energy demand of the cement industry, the Saudi Arabian government has been making efforts to reduce the energy consumption in the country towards a more sustainable.

Energy Demand in Cement Production

The theoretical fuel energy demand for cement clinker production is determined by the energy required for the chemical/mineralogical reactions (1,700 to 1,800 MJ/tonne clinker) and the thermal energy needed for raw material drying and pre-heating. Modern cement plants which were built within the last decade have low energy consumption compared to older plants.  The actual fuel energy use for different kiln systems is in the following ranges (MJ/tonne clinker):

  • 3,000 – 3,800 for dry process, multi-stage (3 – 6 stages) cyclone preheater and precalcining kilns,
  • 3,100 – 4,200 for dry process rotary kilns equipped with cyclone preheaters,
  • 3,300 – 4,500 for semi-dry/semi-wet processes (e.g. Lepol-kilns),
  • Up to 5,000 for dry process long kilns,
  • 5,000 – 6,000 for wet process long kilns and
  • 3,100–6,500 for shaft kilns.

Energy Efficiency in Cement Industry

With new built, state-of-the-art cement plants, usually all technical measures seem to be implemented towards low energy consumption. So, how to reduce it further?

Energy efficiency is based on the following three pillars

  • Technical optimization
  • Alternative raw materials for cement and clinker production
  • Alternative fuels

In Europe, the new energy efficiency directive from 2011 intends to reduce the energy consumption of the overall industry by 20%, achieving savings of 200billion Euros at the energy bill and with the goal to create 2 million new jobs within Europe. This approach will have a significant influence also on the cement industry. Saving 20% of the energy consumption is a challenging goal, especially for plants with state-of-the-art technology.

In older plants modernizations in the fields of grinding, process control and process prediction can, if properly planned and installed, reduce the electricity consumption – sometimes in a two digit number.

Alternative Fuels

Alternative fuels, such as waste-derived fuels or RDF, bear further energy saving potential. The substitution of fossil fuel by alternative sources of energy is common practice in the European cement industry.The German cement industry, for example, substitutes approximately 61% of their fossil fuel demand. The European cement industry reaches an overall substitution rate of at least ca. 20%.

Typical “alternative fuels” available in Saudi Arabia are municipal solid wastes, agro-industrial wastes, industrial wastes and some amount of crop residues. To use alternative or waste-derived fuels, such as municipal solid wastes, dried sewage sludges, drilling wastes etc., a regulatory base has to be developed which sets

  • Types of wastes/alternative fuels,
  • Standards for the production of waste-derived fuels,
  • Emission standards and control mechanism while using alternative fuels and
  • Standards for permitting procedures.

Alternative Raw Materials

The reduction of clinker portion in cement affords another route to reduce energy consumption. In particular, granulated blast furnace slags or even limestone have proven themselves as substitutes in cement production, thus reducing the overall energy consumption.

To force the use of alternative raw materials within the cement industry, also – and again –standards have to be set, where

  • Types of wastes, by-products and other secondary raw materials are defined,
  • Standards for the substitution are set,
  • Guidelines for processing are developed,
  • Control mechanisms are defined.

Conclusions

To reduce the energy consumption, an energy efficiency program, focusing on “production-related energy efficiency” has to be developed. Substantial potential for energy efficiency improvement exists in the cement industry and in individual plants. A portion of this potential will be achieved as part of (natural) modernization and expansion of existing facilities, as well as construction of new plants in particular regions. Still, a relatively large potential for improved energy management practices exists and can be exhausted by determined approaches.

Saudi Arabia’s Road to Fuel Economy

Saudi Arabia is a private car-oriented society, and has one of the world’s highest per capita fuel consumption in the transportation sector. This is primarily due to lack of efficient public transportation and current fuel subsidy policy. The country is witnessing an escalating demand on its domestic energy needs and it is imperative on policymakers to devise policies for conservation of energy resources and reduction of GHGs emissions in the transportation sector. Adapting energy-efficient fuel standards will help Saudi Arabia country to bridge the gap with the developed countries. The enforcement mechanism for the establishment of Saudi fuel economy standards will lead to achievement of strategic energy conservation objectives.

Energy intensity in Saudi Arabia has set high records reflecting the growth of the economy and the increasing demand on fossil energy in the domestic use and heavy industries operations. Energy intensity in the Kingdom was twice the world average in 2010 and with unbalanced growth between energy use and economy, this should rang the bell for the Saudi government to adapt a bundle of energy policies that curtail the increasing growth of energy demand domestically.

CAFE Standards

Corporate Average Fuel Efficiency standard (CAFE) was first enacted after the Energy Policy and Conservation Act of 1975 in the USA. That policy was due to energy security concerns and environmental objectives. The USA current standard is 27.5 mpg for passenger’s vehicle and 20.7mpg for light trucks. Similarly to the USA CAFE objectives, the Kingdom approach is to reduce gasoline consumption and induce conservation and increasing efficiency of the light-duty vehicles (LDV).The proposed standard mandates require that all new and used passenger vehicles and light trucks either imported or locally manufacture should comply with new fuel standards. The framework for this law to be effective will start by January 1, 2016 and fully phased out by December 31, 2025. The Saudi Energy Efficiency Center (SEEC) and other entities including the Saudi Standards, Metrology and Quality Organization, Saudi Customs, and Ministry of Commerce and Industry have been asked to monitor the implementation of the CAFE standards.

The purpose of the fuel standards is to commit the light-duty vehicle manufactures sell their cars in the kingdom and comply with the Saudi CAFE. This standard has a double dividends from the automobile manufacturer side its incentivize them to introduce the up-to-date efficiency technologies and cut the supply the low-efficient technologies to the Saudi market. The Saudi CAFE standard targets an improving in the overall fuel economy with an average of 4% annually. This would lift up the Kingdom’s fuel economy LDVs from its current level of 12 km per liter to 19 km per liter by 2025.

The Saudi CAFE standard shows a focused strategy to setting long-term standards over the course of a given time frame and its committed efforts to manage both newly imported or used LDVs. According to Prince Abdulaziz bin Salman al-Saud, the Saudi transportation sector consumes about 23 percent of the total energy in the kingdom and about 12 million vehicles consume about 811,000 barrels of gasoline and diesel per day. Moreover, there are 7 LDVs entering the market every year with a forecast to reach 20 million by 2030.

Conclusion

Saudi Arabia’s CAFE standard is a means to stimulate energy efficiency and encourage resource conservation and contribute to the environment. This will enable consumers to save money, reduce fossil fuel consumption and strengthen the Kingdom’s role in the fight against climate change.

كفاءة الطاقة في الإمارات العربية المتحدة

إمارة أبو ظبي , هي الوحيدة في مجال انتاج 10.000 ميجاواط من الكهرباء و للمرة الأولى , و بالحديث عن تحسين كفاءة الطاقة في الإمارات العربية المتحدة , الموضوع أصبح يأخذ منحناً جدياً  حيث أن الإستهلاك اليومي للطاقة في أشهر الصيف الحارّة مازال يعاني من النمو المتزايد من سنة إلى أخرى , مع ذروة حاجة وصلت إلى 12 بالمئة . مع غصة كبيرة تركتها نسب استهلاك كبيرة سببها مكيفات الهواء , والتي تشكل نصف الإستهلاك العام من الكهرباء في المنطقة .

إجراءات الحكومة و القطاع التجاري

حسب المستويات التجارية , هناك خطوات ملحوظة تؤخذ للحد من ما يعرف ب " بصمة الكربون " الإماراتية . نظام عزل المباني في إمارة دبي أدى إلى حدوث العديد من المطالبات التي صرحت بأن هذه المباني تستهلك ضعف كفاءة الطاقة منذ تطبيق هذا النظام . هناك خطوات إضافية تجري في مساحات بيئية أخرى مثل كفاءة المياه و إدارة المخلفات مع نيّة في تعزيز الإعتماد على الأنظمة صديقة البيئة لكل مبنى يوافق المعايير و المقاييس البيئة العالمية .

على المستوى الرسمي واصلت هيئة المواصفات و المقاييس الإماراتية تنفيذ برنامج " توحيد كفاءة الطاقة و تصنيفها –Energy Efficiency Standardization and Labelling (EESL ) " . هذا سيعرّفالكفاءة المحددة و التصنيفات المطلوبة لمكيفات هواءغير الأنبوبية  في عام 2011 .

هذه المقاييس ستنضم هذه السنة للمتطلبات الواقعة تحت نفس النظام للعديد من السلع الكهربائية المنزلية بما فيها المصابيح , الغسالات و أجهزة التبريد .المتطلبات التصنيف هذه ستصبح تحت غطاء هذا النظام بشكل إلزامي في حلول عام 2013 لتمكن المستهلك من معرفة أي هذه الأجهزة قد يكون ذو كفاءة أفضل و تشكيل صورة جيدة عن مجموعة خيارات صديقة للبيئة قد تساعده في توفير نقوده على تكاليف التشغيل .نظام (EESL)  سيمتد في عام 2013  ليشمل مكيفات الهواء الأنبوبية و البرّادات .

قطاع النفط و الغاز الإماراتي ايضاً يدرك أهمية أجندة كفاءة الطاقة . قد يبدو أمراً غير متوقع أن يتم التفكير بكيفية حفظ الطاقة بوجود قطاع النفط و احتياطه الذي يصل إلى 97 برميلاً و الغاز 6 تريليون متر مكعب من احتياطي الغاز الطبيعي .القضية هي بأن هذه الإحتياطيات بالرغم من حجمها فهي ليست محدودة , وأن واردات تصدير النفط للخارج أكبر من عرضها في السوق المحلي . و من أجل هذا الغرض , فإن قطاع الغاز و النفط مهتم بالعمل أكثر مع الذين يحاولون خفض الإستهلاك المحلي , مما يؤدي إلى استدامة هذا القطاع بشكل أطول .

جائزة الطاقة الإماراتية أنشأت في عام 2007للتعرف على أفضل طرق تمارس في مجال حفظ الطاقة و إدارتها و التي تعكس الإبتكار , الفعالية من ناحية التكاليف و تدابير كفاءة الطاقة القابلة للتكرار . و بعض هذه الممارسات المتعارف عليها يجب أن تكون ذات تأثير على منطقة الخليج العربي  لتحريك التوعية في مجال الطاقة بشكل واسع و علىكافة شرائح  المجتمع .

أهمية تغيير السلوك

المبادرات الرسمية والبرامج لها مكانها في معركة الحفاظ على كفاءة الطاقة في الإمارات , يجب أن يكون هناك نقلة نوعية شاملة في الثقافة تجاه هذا الموضوع من قبل المواطنين . تحسين الإدراك لدى المجتمع في مجال القضايا البيئية و تحسين التصرفات البيئية و التي لها دور داعم في مجال كفاءة الطاقة ممكن أن يساهم بشكل ملحوظ تجاه الهدف الرئيسي المنشود .

كما تزداد أسعار النفط في الأسواق المحلية , فإن المواطنين الإماراتيين يزيدون العبء على كفاءة البنزين اخذين بعين الإعتبار أنواع السيارات التي يبتاعونها . إن سيارات الدفع الرباعي تتصدر المرتبة الأولى من ناحية المبيعات في الإمارات لكن ميزانيات الأسر تزداد و العديد من الأسر عادية يبحثون عن مركبات صغيرة و أكثر كفاءة . ربما للمرة الأولى تكون تكلفة التشغيل المجملة للسيارات أُخذَت بعين الإعتبار و أصبح تجار السيارات يتطلعون إلى استيعاب أذواق زبائنهم . هذا التوجه الدارج أصبح ملحوظاً حيث أن بعض تجار السيارات لديهم رؤيا قوية بأن يزداد سنويا بيع السيارات الصغيرة و صاحبة الكفاءة العالية .

و تجار السيارات في دبي أيضا لديهم نفس الرؤيا , حيث أنه هناك واحد على الأقل يقوم باستئجار سيارة ذات مواصفات محافظة على البيئة تجذب انتباه شريجة جيدة من المجتمع , كما أن هناك شركات Chevrolet Voltsو Nissanأتاحت فرصة استئجار و تأجير  سيارات كهربائة بشكل سهل .

إن الإستفادة من هذه التوجهات يجعل قطاع التجارة و البيئة مدرَكين بشكل ملحوظ لكن رواد الإقتصاد وحدهم لا يستطيعون تغيير تصرفات المجتمع . هناك العديد من التدابير البسيطة التي يمكن للحكومة و الاقتصاديين إتخاذها لتحفيز المواطنين و تشجيعهم لاتخاذها . بعضهم يعترض أن إطفاء جهاز الحاسوب , الأضاءة و مكيفات الهواء عند الإنتهاء من العمل ربما قد يحفظ الطاقة لكنه ليس كافيا  او مجديا – التدابير الطوعية من هذا النوع لا تؤثر على اتجاهات الطاقة عموما .

و لكن هناك أدلة بأنه إن أضيفت هذه السلوكيات إلى مجمل التدابير كتركيب الإضاءة الوفرة للطاقة , خفض الحرارة و تحسين مكيفات  EESL  الهوائية , سيكون حفظ الطاقة ملحوظا – أي من المحتمل تخفيض استهلاك المبنى للطاقة .

مبدأ حفظ الطاقة لم يشق طريقه بشكل قوي في الإمارات , لكن التغيرات السريعة الملحوظة تنبئ بالمزيد القادم . برامج كفاءة الطاقة الرسمية و التدابير الطوعية ستجتمع لمساعدة الإمارات على إبقاء وضعها الإقتصادي قوياً في المنطقة , و بفعل ذلك لن تصبح هذه الأجندة بعيدة عن التحقيق .

Energy Conservation in Bahrain

bahrain-energyBahrain has one of the highest energy consumption rates in the world. The country uses almost three times more energy per person than the world average. Based on 2014 statistics, the country consumes 11,500 kWh of energy per capita compared with the global average of 3,030 kWh. The country is witnessing high population growth rate, rapid urbanization, industrialization and commercialization with more visitors coming in, causing fast growing domestic energy demand and is posing a major challenge for energy security.

The Government is aware of this challenging task and is continuously planning and implementing projects to enhance the energy production to meet with the growing demand. The issue of efficient use of energy, its conservation and sustainability, use of renewable and non-renewable resources is becoming more important to us. The increasing temperatures and warming on the other hand are also causing more need of air-conditioning and use of electrical appliances along with water usage for domestic and industrial purposes. This phenomenon is continuing in Bahrain and other GCC countries since past two decades with high annual electricity and water consumption rates compared with the rest of the world.

Bahrain’s energy requirement is forecast to more than double from the current energy use. The peak system demand will rise from 3,441 MW to around 8,000 MW. While the concerned authorities are planning for induction of more sustainable renewable energy initiatives, we need to understand the energy consumption scenario in terms of costs. With the prices of electricity and water going up again from March 2017 again, it is imperative that we as consumers need to think and adopt small actions and utilize practices that can conserve energy and ultimately cost.

The country has already embarked on the Energy Efficiency Implementation Program to address the challenge of curbing energy demand in the country over the next years. The National Energy Efficiency Action Plan and the National Renewable Energy Action Plan (NREAP) have already been endorsed. The NREAP aims to achieve long-term sustainability for the energy sector by proposing to increase the share of renewable energy to 5 percent by 2020 and 10 percent by 2030.

Per capita energy consumption in Bahrain is among the highest worldwide

Per capita energy conservation in Bahrain is among the highest worldwide

As individuals, we need to audit how much energy we are using and how we can minimize our usage and conserve it. Whenever we save energy, we not only save money, but also reduce the demand for such fossil fuels as coal, oil, and natural gas. Less burning of fossil fuels also means lower emissions of carbon dioxide (CO2), the primary contributor to global warming, and other pollutants. Energy needs to be conserved not only to cut costs but also to preserve the resources for longer use.

Here are few energy conservation tips we need to follow and adopt:

  • Turning off the lights, electrical and electronic gadgets when not in use.
  • Utilizing energy efficient appliances like LED lights, air conditioners, freezers and washing machines.
  • Service, clean or replace AC filters as recommended.
  • Utilizing normal water for washing machine. Use washing machine and dish washer only when the load is full. Avoid using the dryer with long cycles.
  • Select the most energy-efficient models when replacing your old appliances.
  • Buy the product that is sized to your actual needs and not the largest one available.
  • Turn off AC in unoccupied rooms and try to keep the room cool by keeping the curtains.
  • Make maximum use of sunlight during the day.
  • Water heaters/ Geysers consume a lot of energy. Use them to heat only the amount of water that is required.
  • Unplug electronic devices and chargers when they are not in use. Most new electronics use electricity even when switched off.
  • Allow hot food to cool off before putting it in the refrigerator

Carbon Capture and Storage: Prospects in GCC

Gulf Cooperation Council countries are burgeoning economies which are highly dependent on hydrocarbons to fuel their needs for economic growth. GCC nations are fully aware of the mounting consequences of increasing levels of CO­2 on the environment, mainly attributed to soaring energy demand of domestic and industrial sector. Regional countries are undertaking concrete steps and measures to reduce their carbon footprint through the introduction of renewable energy and energy efficiency measures. Among other options, Carbon Capture and Storage, popularly known as CCS, can be an attractive proposition for GCC nations.

What is CCS

Carbon capture and storage (or carbon capture and sequestration) is the process of capturing waste carbon dioxide from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation. CCS is a potential means of mitigating the contribution of fossil fuel emissions to global warming and ocean acidification. As at September 2012, the Global CCS Institute identified 75 large-scale integrated projects in its 2012 Global Status of CCS report. 16 of these projects are in operation or in construction capturing around 36 million tonnes of CO2 per annum.

Among notable CCS projects world, In Salah project in Algeria is a fully operational onshore gas field with CO2 injection. CO2 is separated from produced gas and reinjected in the producing hydrocarbon reservoir zones. Since 2004, about 1 Mt/a of CO2 has been captured during natural gas extraction and injected into the Krechba geologic formation at a depth of 1,800m. The Krechba formation is expected to store 17Mt CO2 over the life of the project.

CCS Prospects in GCC

GCC accounts for 0.6% of the global population but ironically contributes 2.4% of the global GHG emissions per capita.  GCC countries are among the top-14 per capita emitters of carbon dioxide in the world. The GCC region is witnessing rapid economic growth and massive industrialization which has led to almost 8% growth in power consumption each year. The region is heavily dependent on hydrocarbons combustion for power generation and operation of energy-intensive industries.

There is an urgent need for carbon abatement measures for the industrial sector in Middle East nations as increasing carbon dioxide emissions will have serious repercussions for GCC and adjoining regions. Some of the potential impacts can be rise in sea level, droughts, heat waves, sandstorms, damage to ecosystem, water scarcity and loss of biodiversity. Carbon dioxide emissions reductions can be achieved from point sources such as refineries, power plants, manufacturing industries etc.

At the regional level, GCC nations have both the drivers and environmental gains to adopt the CCS technologies. Some of the GCC countries are already engaged in R&D initiatives, for example, Saudi Arabia has KACST- Technology Innovation Center on Carbon Capture and Sequestration while Saudi Aramco have their own CCS R&D program for CCS. In Qatar there is the Qatar Carbonate and Carbon Storage Research Center while Bahrain has Sitra Carbon Capture System. Recently, Masdar and ADNOC launched Middle East first Joint Venture for carbon capture usage and storage. On a multilateral level, back to 2007, King Abdullah pledged $300 million to finance a research program on the future of energy, environment and climate change. In addition, a sum of $150 million from Qatar, Kuwait and UAE has been allocated to support CCS research.

To sum up, CCS is a viable option to help GCC countries maintain their hydrocarbons-driven economies while enabling low-carbon electricity generation from existing hydrocarbons powerplants.

Environmental Best Practices for MENA Cement Industry

Cement production in MENA region has almost tripled during the last 15 years, mainly on account of high population growth rate, rapid urbanization, increasing industrialization and large-scale infrastructural development. The growth of cement industry in MENA is marked by factors that are directly connected with sustainability, energy efficiency and raw material supply. Although the factors differ from country to country and cannot be generalized, there are major concerns regarding shortage of raw materials, GHG emissions, dependence on fossil fuels and lack of investment in technological innovations.

For the MENA cement sector, key points for an environment-friendly industry are use of alternative raw materials and alternative fuels, energy-efficient equipment and green technologies. As the use of alternative fuels and raw materials is still uncommon in the Middle East, guidelines and regulatory framework have to be defined which can set standards for the use of alternative or waste-derived fuels like municipal solid wastes, dried sewage sludge, agricultural wastes, drilling wastes etc.

Sewage Sludge

An attractive disposal method for sewage sludge is to use it as alternative fuel source in a cement kiln. Dried sewage sludge with high organic content possesses a high calorific value. Due to the high temperature in the kiln the organic content of the sewage sludge will be completely destroyed. The resultant ash is incorporated in the cement matrix. Infact, several European countries, like Germany and Switzerland, have already started adopting this practice for sewage sludge management.

The MENA region produces huge quantity of municipal wastewater which represents a serious problem due to its high treatment costs and risk to environment, human health and marine life. Sewage generation across the region is rising by an astonishing rate of 25 percent every year. Municipal wastewater treatment plants in MENA produce large amounts of sludge whose disposal is a cause of major concern.

For example, Kuwait has 6 wastewater treatment plants, with combined capacity of treating 12,000m³ of municipal wastewater per day, which produce around 250 tons of sludge daily. Similarly Tunisia has approximately 125 wastewater treatment plants which generate around 1 million tons of sewage sludge every year. Currently most of the sewage is sent to landfills. Sewage sludge generation is bound to increase at rapid rates in MENA due to increase in number and size of urban habitats and growing industrialization.

The use of sewage sludge as alternative fuel is a common practice in cement plants around the world, Europe in particular. It could be an attractive business proposition for wastewater treatment plant operators and cement industry in the Middle East to work together to tackle the problem of sewage sludge disposal, and high energy requirements and GHGs emissions from the cement industry.

Use of sludge in cement kilns will led to eco-friendly disposal of municipal sewage

Sewage sludge has relatively high net calorific value of 10-20 MJ/kg as well as lower carbon dioxide emissions factor compared to coal when treated in a cement kiln. Use of sludge in cement kilns can also tackle the problem of safe and eco-friendly disposal of sewage sludge. The cement industry accounts for almost 5 percent of anthropogenic CO2 emissions worldwide. Treating municipal wastes in cement kilns can reduce industry’s reliance on fossil fuels and decrease greenhouse gas emissions.

Municipal Solid Wastes and Biomass

Alternative fuels, such as refuse-derived fuels or RDF, have very good energy-saving potential. The substitution of fossil fuel by alternative sources of energy is common practice in the European cement industry. The German cement industry, for example, substitutes approximately 61% of their fossil fuel demand. Typical alternative fuels available in MENA countries are municipal solid wastes, agro-industrial wastes, industrial wastes and crop residues.

The gross urban waste generation quantity from Middle East countries has crossed 150 million tons per annum. Bahrain, Saudi Arabia, UAE, Qatar and Kuwait rank in the top-ten worldwide in terms of per capita solid waste generation. Solid waste disposal is a big challenge in almost all MENA countries so conversion of MSW to RDF will not ease the environmental situation but also provide an attractive fuel for the regional cement industry. Tens of millions of tyres are discarded across the MENA region each year. Scrap tyres are are an attractive source of energy and find widespread use in countries around the world.

Agriculture plays an important role in the economies of most of the countries in the Middle East and North Africa region.  Despite the fact that MENA is the most water-scarce and dry region in the world, many countries in the region, especially those around the Mediterranean Sea, are highly dependent on agriculture. Egypt is the 14th biggest rice producer in the world and the 8th biggest cotton producer in the world. Similarly Tunisia is one of the biggest producers and exporters of olive oil in the world. Such high biomass production rates should be welcomed by the cement industry since these materials comprise cotton stalks, rice husks and rice straw which serve ideally as alternative fuels. However it is ironical that olive kernels – the waste from Tunisian olive production – is exported to European power plants in order to save fossil fuel-derived CO2 emissions there, while Tunisia imports approximately 90% of its energy demand, consisting of fossil fuels.

Drilling Wastes as Alternative Raw Material

The reduction of clinker portion in cement affords another route to reduce energy consumption. In particular, granulated blast furnace slags or even limestone have proven themselves as substitutes in cement production, thus reducing the overall energy consumption. The Middle East oil and gas industry has made a lot of effort in order to reduce the environmental impact of their activities. The use of drilling wastes and muds is preferable in cement kilns, as a cement kiln can be an attractive, less expensive alternative to a rotary kiln. In cement kilns, drilling wastes with oily components can be used in a fuel-blending program to substitute for fuel that would otherwise be needed to fire the kiln.

Conclusions

The cement industry can play a significant role in the sustainable development in the Arab countries, e.g. by reducing fossil fuel emissions with the use of refused derived fuels (RDF) made from municipal solid waste or biomass pellets. The cement companies in the Middle East can contribute to sustainability also by improving their own internal practices such as improving energy efficiency and implementing recycling programs. Businesses can show commitments to sustainability through voluntary adopting the concepts of social and environmental responsibilities, implementing cleaner production practices, and accepting extended responsibilities for their products.  

The major points of consideration are types of wastes and alternative fuels that may be used, standards for production of waste-derived fuels, emission standards and control mechanisms, permitting procedures etc. Appropriate standards also need to be established for alternative raw materials that are to be used for clinker and cement production.

Environmental Sustainability in Qatar: Perspectives

qatar-ghg-emissionsIn recent years, the concept of environmental sustainability is slowly, but steadily, getting prominence, both in the public and private sectors in Qatar. Mounting environmental pressure has led to the development of new initiatives in several state-owned and private companies. As a major fossil exporter and one of the wealthiest countries, Qatar should do its fair share in reducing domestic greenhouse gas emissions and developing strong climate adaptation plans.

Many companies are investing heavily in replacing old turbines, boilers, and furnaces, minimizing GHG and non-GHG emissions, and wastewater discharge. The new companies that were set up in last decade are adopting the best available technologies, and they are on a par of excellence with the global environmental standards. Because of national targets to minimize flaring emissions, all of the oil and gas companies have been marshaled under the national initiative by setting goals, allocating investment and monitoring the yearly changes. So far, this initiative has been remarkably successful. For example, the direct benefit of flaring reduction resulted in savings of natural gas and emissions.

The government should hasten its steps in developing a comprehensive climate policy framework addressing all sectors, with a special focus on energy-intensive industries. The industrial sector is the major contributor to country’s economy and will continue to retain this status for the next several decades. Therefore, the government and the industrial sector must prepare a comprehensive roadmap and strategic framework under the broader climate policy framework, such as “Industrial Decarbonisation Strategy”. The strategy must assess all possibilities of decarbonising the industry and set ambitious goals to minimize GHG emissions for the short and long-term.

In addition, the framework should focus on potential structural changes in the global market, technological dynamics or deployment of disruptive technologies, domestic institutional reforms, and relevant policies that can support decarbonization. The policy should foster the development and implementation of wide-ranging innovative low-carbon technologies, processes, standards, norms and legislations that enable decarbonisation of the sector by 2050. The legislative instruments should include emission caps, internalizing social and environmental costs and taxation on emissions for the industrial sector. This is also echoed in the first Natural Resource Management Strategy.

The government should press ahead with this proposition; expediting the creation of new regulations, developing a strong support system for large and small/medium sized industries and ensuring transparency and accountability. Methane is the second major source of emission from natural gas production and processing facilities. Many companies fail to measure/monitor methane emissions from their facilities. I suggest that the Ministry of Environment undertake a Methane Monitoring Initiative to measure methane emissions from extraction to delivery and also to prepare a standardization method for estimating and reporting emissions from different sources.

The Ministry must create an effective, well-functioning, transparent and less bureaucratic support mechanism for companies (medium/small scale industries or SMEs) that lack technical and financial capacity. There are several piecemeal initiatives started by different companies that are already helping in this direction. However, they are fragmented, lack coherence, monitoring, and reporting. It is important to compile all of the initiatives and develop key performance indicators and analyse the trend. So far, there is only one project accredited under the Clean Development Mechanism (Al Shaheen Oil Field Gas Recovery and Utilization Project, started in 2007). The government should exploit all possible opportunities with regard to reducing emissions and increasing economic savings. These are remarkable achievements and these companies must be recognized for their activities. Likewise, policymakers should capitalize on these efforts and raise the bar and set definitive goals and strict timelines for implementation.

According to the Resolution of the Council of Ministers No. 15 of 2011, the respective agencies must propose policies and action plans to reduce GHG emissions and set up a database within the requirements of the UNFCCC convention and Kyoto protocol. Unfortunately, there was no tangible response to this Resolution. So far, Qatar has published only one national communication. Under the initiative of Qatar Petroleum HSE, many companies started to publish their emission data in their annual sustainability report, however, some companies continue to withhold the data. Since it is a voluntary process, there is no incentive for companies to report.

It is strongly recommended that the Ministry of Municipality and Environment (MME) and Ministry of Energy and Industry (MoEI) issue a joint decree for a mandatory GHG and non-GHG pollution monitoring and disclosure framework. The disclosure framework must include a well-designed surveillance system to ensure transparency and accountability. Additionally, the disclosure framework will be useful in documenting the trend of overall emissions and how the new policies, regulations and technological replacements are shifting the trend. As a result of documenting emission trends, one can notice the effectiveness of energy management initiatives, which provides opportunities and encourage other companies to learn from best practices. Companies that emit more than 25,000 tonnes CO2eq should quantify, verify and publish in a single-window system that can be accessed by other ministries and the public alike.

Effective Energy Management for Businesses

energy-management-middle-east-businessesMiddle East has been witnessing a rapid increase in energy consumption due to high degree of industrialization, high standards of living and exponential increase in population. Infact, the level of primary energy consumption in the Middle East is among the highest worldwide.  These factors have made businesses in Middle East to realize that effective energy management is not only good for the businesses but also an essential requirement.

In recent years, many businesses in the Middle East have come up with dynamic strategies to achieve immediate reduction in energy consumption. This trend towards effective energy management is expected to continue to grow in the region in the coming years on account on changing regulations and growing awareness on energy conservation.

Ingredients of Effective Energy Management Plan

For an energy management plan to succeed, the entire organization including its employees and management team, should be committed to the implementation of energy management strategy whose main elements are:

  • Goal-setting: how much energy reduction do you want to achieve?
  • Number-crunching: how much energy do you consume?
  • Identifying energy-guzzlers: What are major consumption units and what measures can be taken to reduce consumption
  • Technology and automation: Smart metering, schedule-based lighting, occupancy sensors, HVAC control and latest technological innovation provides an active approach to energy management
  • Continuous review and management: Regular performance monitoring is essential to check the progress towards your energy-saving goals. 

Hurdles to Overcome

​Lack of incentives to reduce energy consumption is a major hurdle faced by businesses in the Middle East. In the GCC region, electricity is usually provided at heavily subsidized rates which fail to provide the motivation to the consumer to reduce energy consumption. Most of the commercial buildings in the Middle East consume huge amount of energy in the form of HVAC, lighting, ventilation etc., and there is a real need to make such buildings ‘ energy smart’ in the real sense of the word.

Role of Technology

Technology plays a vital role in reducing energy consumption as energy-savings are not limited to power consumption by HVAC, lighting or ventilations, but also encompass optimization of energy use, building infrastructure, supply chain networks, product design, transportation networks etc. Businesses in the Middle East may strive for energy-smart buildings, smart grid systems and renewable energy sources (like rooptop solar and biogas systems) to improve their long-term sustainability and more effective cost-management.
