Alternative fuel

Alternative fuel is a fuel that is, as its name implies, an alternative to conventional oil based fuels: petrol, diesel, kerosene…

Very diverse, these fuels are developed to compensate for the problems related to shortages (embargo, exhaustion of reserves), energy independence (oil shocks), economic cost (Escalation of the price of oil) or environmental impact (pollution, greenhouse effect gas) relative to oil.

There are three solutions for providing alternative fuels:

  • The use of other fossil hydrocarbons;
  • the use of biomass;
  • a change in the energy carrier.

Using other fossil hydrocarbons

The first solution consists in using or transforming coal, natural gas or refinery products. This is the case of the Fischer-Tropsch processes Coal-to-Liquid and Gas-to-Liquid that produce fuel from coal and natural gas, and LPG or NGV to power some vehicles.

Using biomass

The second solution is to use biogas, biofuels and fuels produced from biomass (energy crop, waste) by the Biomass-to-Liquid process.

The last method is to use an energy carrier capable of using the energy produced by a power plant in a vehicle. This is the method for using electricity, dihydrogen and compressed air in electric vehicles and rechargeable hybrid vehicles, fuel cell vehicles and vehicles with compressed air engines.
