Biorefinery – Source of Advanced Biofuels

A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and value-added chemicals from biomass. A biorefinery is analogous to a petroleum refinery, which produces multiple fuels and products from petroleum. By producing several products, a biorefinery takes advantage of the various components in biomass and their intermediates, therefore […]

A Glance at Lignocellulosic Biomass

First-generation biofuels (produced primarily from food crops such as grains, sugar beet and oil seeds) are limited in their ability to achieve targets for oil-product substitution, climate change mitigation, and economic growth. Their sustainable production is under scanner, as is the possibility of creating undue competition for land and water used for food and fibre […]

Global Biomass Energy Outlook

Biomass energy has rapidly become a vital part of the global renewable energy mix and account for an ever-growing share of electric capacity added worldwide. As per the REN 2014, global biopower (including solid, liquid and gaseous fuels) electricity generation capacity was 88 GW in the year 2013. With 4.4 GW capacity, India ranked 5th […]

Biodiesel Industry in India

The biodiesel industry in India is still in infancy despite the fact that demand for diesel is five times higher than that for petrol. The government’s ambitious plan of producing sufficient biodiesel by 2011-2012 to meet its mandate of 20 percent diesel blending is unrealized due to a lack of sufficient Jatropha seeds to produce biodiesel. Currently,Jatropha occupies […]

Biodiesel Feedstock in India

Biodiesel is mostly produced from the oils extracted from the seeds of Jatropha. Apart from Jatropha, Pongamia pinnata, Mahua, Neem and Castor are also considered as good source of non-edible oil-based biodiesel. Jatropha is a genus of nearly 175 species of shrubs, low-growing plants, and trees.  However, discussions of Jatropha as a biodiesel are actually means a particular species of the […]

Biomass Energy in the Philippines

Like any developing country, the Philippines is facing a formidable challenge of fostering sustainable energy options to support the energy requirements of its economic and social development goals with minimal adverse effects on the environment. In the Philippines, renewable energy sources contribute 43 percent to the country’s primary energy mix, one of the highest in […]

An Introduction to Biofuels

‘Biofuel’ refers to liquid or gaseous fuels for the transport sector that are predominantly produced from biomass. A variety of biofuels can be produced from biomass resources including liquid fuels, such as ethanol, methanol, biodiesel, Fischer-Tropsch diesel, and gaseous fuels, such as hydrogen and methane. The biomass resource base for biofuel production is composed of […]

Energy Scenario in Malaysia

Malaysia, with population of about 28 million, is one of the fastest-growing economies in Asia. Although blessed with petroleum resources, this strategically-important Southeast Asian nation is relatively a small producer with reserves of 5.5 billion barrels of oil and 88 trillion cubic feet of natural gas. Malaysia has significant natural gas exploration and development in […]

Pretreatment of Lignocellulosic Biomass

Lignocellulosic biomass consists mainly of lignin and polysaccharides cellulose and hemicellulose. Compared with the production of ethanol from first-generation feedstocks, the use of lignocellulosic biomass is more complicated because the polysaccharides are more stable and the pentose sugars are not readily fermentable by Saccharomyces cerevisiae.  In order to convert lignocellulosic biomass to biofuels the polysaccharides must […]

Biomass Conversion Technologies

Bioenergy generation can be tailored to rural or urban environments, and utilized in domestic, commercial or industrial applications. A wide range of technologies are available for realizing the potential of biomass as an energy source, ranging from very simple systems for disposing of dry waste to more complex technologies capable of dealing with large amounts of […]

Jatropha – The Wonder Crop

 Jatropha is a genus of nearly 175 species of shrubs, low-growing plants, and trees.  However, discussions of Jatropha as a biodiesel 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. Jatropha curcas is […]

Algae Biorefinery Project in Saudi Arabia

The King Abdulaziz City for Science & Technology (KACST) is funding an innovative project called Saudi Arabia Biorefinery from Algae (SABA Project) to screen for lipid hyper-producers species in Saudi Arabia coastal waters. These species will be the basis for next-generation algal biofuel production. The goal of this project is to increase research and training […]

Biomass Energy Resources in Malaysia

Malaysia is gifted with conventional energy resources such as oil and gas as well as renewables like hydro, biomass and solar energy. Malaysia’s commercial demand for energy is projected to continue its upward trend, from 1,244 PetaJoule (PJ) in 2000 to an estimated 2,218 PJ in 2010. This consumption growth is mainly driven by industrialisation. […]

Renewable Energy in South Africa

South Africa, the most industrialized country in Africa, is highly dependent on conventional fuels which make it one of the largest emitters of greenhouse gases in the world. Coal provides around 75% of the fossil fuel demand and accounts for 90% of power generation in the country. A smooth transition to a low-carbon society requires […]

A Primer on Biodiesel

Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources. The fuel 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, […]
