Biodiesel

Definition

Mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats for use in diesel engines. It refers to pure fuel before blending with conventional diesel fuel. Blends are denoted as, "BXX" with "XX" representing the percentage of biodiesel

Definition

Mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats for use in diesel engines. It refers to pure fuel before blending with conventional diesel fuel. Blends are denoted as, "BXX" with "XX" representing the percentage of biodiesel contained in the blend (ie: B20 is 20% biodiesel, 80% petroleum diesel).

Bioethanol

Description

Bioethanol

Description

Bioethanol is ethanol of biological origin. Crops containing sugar or starch grown for energy use include sugar beet, sugar cane, maize and wheat. "2nd generation" bioethanol will be made from cellulose from, e.g. waste straw and stover, willow and popular trees, sawdust, reed canary grass, switchgrass, Miscanthus.

. Oilpalm is another source of biofuel. Biofuel producing algae can be cultivated in ponds in conjunction with carbon power plants to capture their CO2 emissions. Biodiesel crops should preferably target land that is less favorable for food crop production such as marginal land, salt-affected land, wasteland, etc. to avoid unwarranted competition with food production.

Biogas

Description

Biogas

Description

Biogas typically refers to a (biofuel) gas produced by the anaerobic digestion or fermentation of organic matter including manure, sewage sludge, municipal solid waste, biodegradable waste or any other biodegradable feedstock, under anaerobic conditions. Biogas is comprised primarily of methane and carbon dioxide.
