WebHydrogen production is the family of industrial methods for generating hydrogen gas. As of 2024, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas and other light hydrocarbons, partial oxidation of heavier hydrocarbons, and coal gasification. Other methods of hydrogen production include biomass gasification, zero … WebTechnologies for hydrogen (H2) production fall into four main categories: Thermal Processes: Thermal processes use the energy in various feedstocks (natural gas, coal, biomass, etc.) to release the H2 that is part of their molecular structure. The main hydrogen production technologies using fossil fuels are all thermal processes, and include … react router dom clear history
