Introduction to Trigeneration

Trigeneration refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a biomass fuel or a solar heat collector. Conventional coal or nuclear-powered power stations convert only about 33% of their input heat to electricity. The remaining 67% emerges from the turbines as low-grade waste heat with no significant local uses so it is usually rejected to the environment. What is Trigeneration In a trigeneration system, the supply of high-temperature heat first drives a gas or steam turbine powered generator and the resulting low-temperature waste heat is then used for water or space heating. Such systems can attain higher … Continue reading

Concept of Energy Management

Energy management is the best solution for direct and immediate reduction of energy consumption. For the last few decades we have been exploring various alternatives to conventional sources of energy like solar, wind and biomass energy. However, due attention must also be given to best utilization of energy, improvement in energy efficiencies and optimum management of energy resources. Infact, energy management deals with already existing sources and actual consumption. It includes planning and operation of energy-related production and consumption units. The main objectives of energy management are resource conservation, climate protection and cost savings. The central task of energy management is to … Continue reading

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 … Continue reading

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 … Continue reading

Peak Oil: Perspectives for Saudi Arabia

The 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 … Continue reading

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 … Continue reading

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. … Continue reading

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 … Continue reading

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 … Continue reading

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) … Continue reading
