Technologies 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 reforming, gasification, and pyrolysis.
