  2. Alternative fuel - Wikipedia

    en.wikipedia.org/wiki/Alternative_fuel

    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 ...

  3. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    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 ...

  4. Methanol fuel - Wikipedia

    en.wikipedia.org/wiki/Methanol_fuel

    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 .

    As researchers discover new ways to engineer plants for biofuel production, the variety of biomasses continues to grow.

  6. Biofuel - Wikipedia

    en.wikipedia.org/wiki/Biofuel

    Biofuels are biomass-derived fuels from plants, animals, or waste; depending on which type of biomass is used, they could lower CO 2 emissions by 20–98% compared to conventional jet fuel. [68] The first test flight using blended biofuel was in 2008, and in 2011, blended fuels with 50% biofuels were allowed on commercial flights.

  7. Renewable fuels - Wikipedia

    en.wikipedia.org/wiki/Renewable_fuels

    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.

  8. What is Flex Fuel? The pros and cons of flexible fuel vehicles

    www.aol.com/flex-fuel-e10-e15-e85-125300382.html

    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.

  9. P-series fuels - Wikipedia

    en.wikipedia.org/wiki/P-series_fuels

    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 ...
