Biogas Potential in the Middle East

Anaerobic digestion is the natural biological process which stabilizes organic waste in the absence of air and transforms it into biofertilizer and biogas. It is a reliable technology for the treatment of wet, organic waste.  Organic waste from various sources is biochemically degraded in highly controlled, oxygen-free conditions circumstances resulting in the production of biogas which can be used to produce both electricity and heat. Anaerobic digestion is particularly suited to wet organic material and is commonly used for treating animal manure, organic fraction of MSW, sewage and industrial effluents. Anaerobic digestion is a unique treatment solution for organic wastes … Continue reading

Prospects of Algae Biofuels in GCC

Algae biofuels have the potential to become a renewable, cost-effective alternative for fossil fuels with reduced impact on the environment. Algae hold tremendous potential to provide a non-food, high-yield, non-arable land use source of renewable fuels like biodiesel, bioethanol, hydrogen etc. Microalgae are considered as a potential oleo-feedstock, as they produce lipids through photosynthesis, i.e. using only CO2, water, sunlight, phosphates, nitrates and other (oligo) elements that can be found in residual waters. Algae also produce proteins, isoprenoids and polysaccharides. Some strains of algae ferment sugars to produce alcohols, under the right growing conditions. Their biomass can be processed to … Continue reading

Biofuels in Jordan: Perspectives

Jordan has good biofuels production potential in the form of crop residues, agro-industrial wastes and urban wastes. Biomass energy sector in Jordan is slowly, but steadily, developing. As per a recent World Bank report, the country is currently generating 3.5MW of power from biomass resources which represent 0.1% of the total energy demand in the country. However there is no available data on the amount of biofuels produced in Jordan. Jordan produces significant amount of biofuel feedstock in the form of lignocellulosic biomass, used cooking oil, animal tallow, agro-industrial wastes, industrial effluents etc.  In Jordan, transportation sector alone is responsible of 51% of final … Continue reading

الطحالب – معمل وقود حيوي

اتجهت أبحاث الخبراء والمتخصصين فى الفترة الأخيرة إلى التركيز علي إنتاج الوقود الحيوى من الطحالب الخضراء، خاصة بعد إقرار بدء مرحلة نضوب النفط فى فترة زمنية قريبة، وأنه سينضب أكثر من 95% من مصادر البترول الموجودة على سطح الأرض.   وايضا مشكله الغذاء المحتمل حدوثها في حاله استخدام المنتجات الزراعيه او مخلفاتها في الوقود الحيوي لانتاج منتجات الوقود مثل وقود الديزل الحيوي, الايثانول, الجازولين الحيوي و غيرهم من منتجات الوقود الحيوي. وقد اشارت االعديد من الدراسات الحديثه الي ان الطحالب الخضراء كمصدر للوقود تندرج تحت لواء مصادر الطاقه المتجددة وخاصا بعد التزايد المستمر في سعر الوقود الاحفوري. فهي تنمو بسرعة ولها … Continue reading

5 Compelling Reasons To Switch To Biofuel

Biofuel is created from plant-based materials. Several studies prove that it can deliver performance that can rival the performance produced by fossil fuels such as diesel and petroleum. As a result, it’s no surprise that the use of biofuels has increased in popularity substantially in recent years as a leading petroleum alternative. However, if you are still a bit sceptical about making the switch, we have listed some compelling reasons to finally switch to the eco-friendly choice and start using HVO fuel. 1. Help Enhance Air Quality Diesel and other fossil fuels are undeniably bad for the environment as they … Continue reading

How Agricultural Sector Can Help the Renewable Energy Sector?

The continuous rise in fossil energy prices, combined with climate change concerns and progress in renewable energy sector, has catalyzed interest in clean energy systems across the MENA region, especially in the Mediterranean. The Mediterranean region has abundant renewable resources, such as wind, solar, and biomass, which makes it a fertile zone for renewable energy developments. The agricultural sector has played a key role in the progress of renewable energy sector around the world as it provides large areas where renewable energy projects are built and is also the predominant feedstock source for biomass energy projects. For example, agricultural sector … Continue reading

Everything You Need to Know About Jatropha

Jatropha is a genus of nearly 175 species of shrubs, low-growing plants, and trees.  However, discussions of Jatropha as a biodiesel feedstock are actually means a particular species of the plant, Jatropha curcas. The plant is indigenous to parts of Central America, however it has spread to other tropical and subtropical regions in Africa and Asia. What is Jatropha? Jatropha curcas is a perennial shrub that, on average, grows approximately three to five meters in height. It has smooth grey bark with large and pale green leaves. The plant produces flowers and fruits are produced in winter or throughout the … Continue reading

Renewable Energy in Algeria

Algeria plays a key role in world energy markets as a leading producer and exporter of natural gas and liquefied natural gas. Algeria’s energy mix in 2010 was almost exclusively based on fossil fuels, especially natural gas (93%). However, Algeria has enormous renewable energy potential, mainly solar, which the government is trying to harness by launching an ambitious Renewable Energy and Energy Efficiency Program. “Everywhere there is someone or something trying to make a difference. In this case, Algeria is playing an important role in producing and exporting natural gas and liquefied natural gas. But, sometimes it’s just about understanding … Continue reading

A Historic Timeline Of Renewable Energy

The oldest and most prominent sources of renewable energy can be separated into five clear categories – hydropower, solar energy, wind energy, geothermal energy and bioenergy. To document the history of these renewable energy sources from primitive use through the industrial revolution and into the 21st century, Compare the Market has created an infographic that tracks the known timeline of each source.   The research that went into informing the infographic also touches on the future of each energy source, including the countries that are leading the way by means of capacity and implementation of new technologies.

A Primer on Biodiesel

Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources. This biofuel is a mixture of fatty acid alkyl esters made from vegetable oils, animal fats or recycled greases. Where available, biodiesel can be used in compression-ignition (diesel) engines in its pure form with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulphur and aromatics. It is usually used as a petroleum diesel additive to reduce levels of particulates, carbon monoxide, hydrocarbons and toxics from diesel-powered vehicles. When used as an additive, the resulting diesel fuel may be called B5, B10 … Continue reading
