A biofuel may be a fuel that contains energy from geologically recent carbon fixation. These fuels are created from living organisms. Samples of this carbon fixation occur in plants and microalgae. These fuels are created by a biomass conversion (biomass refers to recently living organisms, most frequently referred to plants or plant-derived materials). This biomass may be reborn to convenient energy containing substances in 3 totally different ways: thermal conversion, chemical conversion, and organic chemistry conversion. This biomass conversion may end up in fuel in solid, liquid, or gas kind. This new biomass may be used for biofuels. Biofuels have accrued in quality thanks to rising oil costs and also the want for energy security. Bioethanol is Associate in nursing alcohol created by fermentation, largely from carbohydrates made in sugar or starch crops like corn or sugarcane. Plastic biomass, derived from non-food sources, like trees and grasses, is additionally being developed as a feedstock for grain alcohol production. Grain alcohols are often used as a fuel for vehicles in its pure kind, however it's sometimes used as a gasolene additive to extend hydrocarbon and improve vehicle emissions. Two types of fuels are used for transportation namely a) first generation fuels which include Bio alcohols, Biodiesel, Green diesel, biofuel gasoline, vegetable oil, bioethers, biogas, syngas, solid biofuels b) Second generation fuels which are advanced fuels.
