Sources of Hydrogen
Hydrogen is now made from natural gas (methane), petroleum, coal, various chemical reactions, and from biomass (landfill waste, wastewater sludge, and livestock waste). It can also be made from water by electrolysis.
Hydrogen can be made from renewable resources, such as wind or solar.
Hydrogen is currently made primarily from natural gas (methane), which is non-renewable.
Methane is a recycled fuel (and therefore renewable) when made by anaerobic digestion of biomass.
Hydrogen production from hydrocarbons can also produce carbon, which in some forms has ten times the strength of steel. With some research this carbon could be used for automobile bodies and structural members.
