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.
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
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]
Most gasoline used in the United States is blended to E10, which contains only 10% ethanol. The May 2015 rule changes thus created modest incentives to make greater use of E85 and E15, which contain more ethanol. [8] Many in the biofuel industry argue that the EPA abused its waiver authority by setting RVOs lower than the statutory minimums.
One of the many policy tools used to promote biofuel fuels is a minimum renewable fuel usage requirement. In the United States, this usage requirement is known as the Renewable Fuel Standard (RFS), whereby a minimum volume of biofuels is to be used in the national transportation fuel supply each year.
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. ...
Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...
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 ...
