Efficiency for methanol synthesis of hydrogen and carbon dioxide currently is 79 to 80%. [19] Thus the efficiency for production of methanol from electricity and carbon dioxide is about 59 to 78%. If CO 2 is not directly available but is obtained by direct air capture then the efficiency amounts to 50-60 % for methanol production by use of ...

The stored energy can be recovered by burning the methanol in a combustion engine, releasing carbon dioxide, water, and heat. Methane can be produced in a similar reaction. Special precautions against methane leaks are important since methane is nearly 100 times as potent as CO 2 , regarding the 20-year global warming potential .
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). Compared to ...
Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures: log 10 (P) = −(0.05223)a/T + b, where P is in mmHg, T is in kelvins, a = 38324, and b = 8.8017.
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.

Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
