The group of industrial processes for producing hydrogen gas is known as hydrogen production. As of 2020, coal gasification, partial oxidation of heavier hydrocarbons, steam reforming of natural gas, and other light hydrocarbons all contribute to the bulk (95%) of hydrogen generated from fossil fuels. Other techniques of producing hydrogen include electrolysis of water, methane pyrolysis with no CO2 emissions, and biomass gasification. The later procedures, methane pyrolysis and water electrolysis, may be carried out instantly using any electrical source, including solar power. Since hydrogen is needed for so many crucial chemical reactions, its generation is crucial in any industrialised civilization. Globally, 87 million tonnes of hydrogen were produced in 2020 for a variety of purposes, including the production of ammonia and the refining of oil.
