bensin hijauEthanol has powered automobiles for more than a century. Ford designed his model T for ethanol as a fuel. Gradually petroleum took over and became the dominating transport fuel. In the seventies Brazil adopted an ethanol strategy and today motor fuel grade ethanol (MFGE) is an extremely fast growing market worldwide.

Bioethanol is renewable, because it is made from glucose created in green plants by the sun, the so called photosynthesis:

(1) 6CO2 + 6H2O + sunshine ? C6H12O6 + 6O2
Sun energy transforms carbon dioxide (CO2) into glucose (C6H12O6). This glucose is transformed once again to ethanol (C2H6O) by classic yeast fermentation:
(2) C6H12O6 ? 2C2H6O + 2CO2 + heat
Heat is released calling for cooling of the fermentation vessels and heat is released again when the ethanol is burned in the combustion engine:
(3) C2H6O + 3O2 ? 2CO2 + 3H2O + heat Read more >>
