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 .
Methanol is a possible biofuel, however, when the syngas is derived from biomass. In theory, methanol can also be produced from sustainably sourced biomass and ultimately carbon dioxide, and by hydrogen electrolysis using nuclear power, geothermal power or some other renewable energy source (see Carbon Recycling International ).
Methanol has a higher octane rating than gasoline but a lower energy density, and can be mixed with other fuels or used on its own. It may also be used in the production of more complex hydrocarbons and polymers. Direct methanol fuel cells have been developed by Caltech's Jet Propulsion Laboratory to convert methanol and oxygen into electricity ...
Ethanol blends of 15%, or E15, just got a green light from the Supreme Court. Trade groups representing the oil, food, and automaker industries challenged that such high blends of ethanol would ...
Biobutanol is often claimed to provide a direct replacement for gasoline, because it will produce more energy than ethanol and allegedly can be burned "straight" in existing gasoline engines (without modification to the engine or car), [29] is less corrosive and less water-soluble than ethanol, and could be distributed via existing infrastructures.
Methanol and ethanol fuel are primary sources of energy; they are convenient fuels for storing and transporting energy. These alcohols can be used in internal combustion engines as alternative fuels. Butane has another advantage: it is the only alcohol-based motor fuel that can be transported readily by existing petroleum-product pipeline ...
The methanol used in most biodiesel production processes is made using fossil fuel inputs. However, there are sources of renewable methanol made using carbon dioxide or biomass as feedstock, making their production processes free of fossil fuels. [75] A by-product of the transesterification process is the production of glycerol. For every 1 ...
