When we talk about replacing gasoline as the fuel we use to power our vehicles‚ biomass‚ hydrogen‚ and fuel cells are the three most talked about alternatives. Biomass‚ which is organic material made from plants and animals‚ contains stored energy from the sun. Biomass in the form of bio fuels can be used to make the same products
