Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial bio waste.
An enzymatic biofuel cell is a specific type of fuel cell that uses enzymes as a catalyst to oxidize its fuel, rather than precious metals. Enzymatic biofuel cells, while currently confined to research facilities, are widely prized for the promise they hold in terms of their relatively inexpensive components and fuels, as well as a potential power source for bionic implants.
Any fuel produced from agricultural produce or organic waste is a biofuel. Humans have used biofuels since time immemorial — for example, burning wood and manure for cooking, heating and light. ...
Since biomass can also be used as a fuel directly (e.g. wood logs), the terms biomass and biofuel have sometimes been used interchangeably. However, the term biomass usually denotes the biological raw material the fuel is made of. The terms biofuel or biogas are generally reserved for liquid or gaseous fuels respectively. [8]
A biofuel cell uses living organisms to produce electricity. It may refer to: Microbial fuel cell, a bio-electrochemical system that drives a current by using bacteria and mimicking bacterial interactions found in nature; Enzymatic biofuel cell, a type of fuel cell that uses enzymes rather than precious metals as a catalyst to oxidize its fuel
First generation biofuels such as biodiesel [4] are produced directly from crops, such as cereals, maize, sugar beet and cane, and rapeseed. Second generation fuels are produced from byproducts from production of food and other goods, as well as from household waste, used frying oil from restaurants, and slaughterhouse waste. [5]
Biomass is a term used in several contexts: in the context of ecology it means living organisms, [1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, [ 2 ] from plants and algae, [ 3 ] from plants and ...
The German government has a Biofuels Roadmap in which they expect to reach 10% biofuels by 2010 with the diesel 10% coming from fuel made from vegetable oil. [18] From 2005 to 2007 a number of types of vegetable oil have doubled in price. The rise in vegetable oil prices is largely attributed to biofuel demand. [19]
