Biofuels are different from fossil fuels in regard to carbon emissions being short term, but are similar to fossil fuels in that biofuels contribute to air pollution. Burning produces airborne carbon particulates, carbon monoxide and nitrous oxides. [83] The WHO estimates 3.7 million premature deaths worldwide in 2012 due to air pollution. [84]
Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane , natural gas , methane , and ammonia ; biofuels like biodiesel , bioalcohol , and refuse-derived fuel ; and other renewable fuels like hydrogen and ...
Ongoing research dedicated to identifying and accessing renewable energy sources has experts looking at how biofuels fit into a more sustainable future.
Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO 2 ) as a feedstock . Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels , which are made by chemically hydrogenating carbon dioxide, and biofuels ...
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.
P-series fuels are a family of renewable, non-petroleum, liquid fuels that can substitute for gasoline. The blend of methyl tetrahydrofuran (MTHF), ethanol, and hydrocarbon constitute the P-series fuel. These fuels are clear, high-octane alternative fuels that can be used in flexible fuel vehicles. It addresses 3 problems: the need for non ...
Specially equipped vehicles designated as Flex Fuel capable can run on E85, a mix that's as high as 85% ethanol and just 15% gasoline. But, nearly all cars are already using a gasoline-ethanol mix.
Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel , although it is more toxic than ethanol and has a lower energy density than gasoline .
