- A nonrenewable source of energy that can be converted into methanol
- Can be used to make methanol
- Produces more energy than ethanol, does not need to be mixed with gasoline
- Burns slower than gasoline, and gives a smoother engine performance
- Involves exposing organic matter to heat in the presence of oxygen.
- Biomass is exposed to high temperatures without any oxygen present.
- Biomass is exposed to heat in a low-oxygen environment, so that it converts to a gas
- In this process bacteria turn the organic material into biogas,
- Biomass can be exposed to yeast to convert its sugar content into ethanol.
- Biomass can be transformed into liquid, solid, or gaseous fuels, collectively called bioenergy.
