The most common and cost-effective technology is natural gas reforming. It involves combining natural gas with high-temperature steam to generate synthesis gas, which is a combination of hydrogen, carbon monoxide, and a trace of carbon dioxide. Carbon monoxide and water can be combined to produce more hydrogen. Another method is gasification, which involves combining coal or biomass with steam and oxygen to generate synthesis gas containing hydrogen and carbon monoxide.

An electric current is used to split water into hydrogen and oxygen. Electrolysis becomes a viable way for hydrogen synthesis when driven by renewable sources such as solar or wind energy. Power-to-hydrogen projects use surplus renewable power to generate hydrogen via electrolysis, resulting in environmental advantages.
