Currently the efficiency for hydrogen production by water electrolysis of electricity amounts to 75 to 85% [19] with potential up to 93% until 2030. [25] 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%.
Enzymes can be used instead of fermentation. Methanol is the simpler molecule, and ethanol can be made from methanol. Methanol can be produced industrially from nearly any biomass, including animal waste, or from carbon dioxide and water or steam by first converting the biomass to synthesis gas in a gasifier. It can also be produced in a ...
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.
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 .

The woes of Greg Focker aren't over just yet. Ben Stiller, Robert De Niro, Teri Polo, and Blythe Danner are in early talks to return for a fourth Meet the Parents movie, nearly 15 years after they ...
After removing hydrogen sulfide and carbon dioxide , which form as side products during the gasification step, methanol can be made using conventional methods. [15] This route can offer renewable methanol production from biomass at efficiencies up to 75%. [17] Production methods using carbon dioxide as a feedstock have also been proposed.
