Hydrogen SourcesNatural gas reforming—"synthesis gas" is created by reacting natural gas with high-temperature steam or by partial oxidation, then the synthesis gas is reacted with water to produce hydrogen. Gasification—Coal or biomass is converted into gaseous components and then into synthesis gas, which is reacted with steam to produce hydrogen. Liquid reforming—renewable liquid fuels such as ethanol are reacted with high-temperature steam to produce hydrogen near the point of end-use. High-temperature thermochemical water-splitting—high temperatures generated by solar concentrators or nuclear reactors drive chemical reactions that split water to produce hydrogen. Photobiological—microbes such as green algae consume water in the presence of sunlight, producing hydrogen as a byproduct Chemical Reaction- Combining an oxidant with a metalic, example: iron oxide (rust), discharging hydrogen. Electrolysis—an electric current generated by renewable energy technologies, such as wind or solar, splits water into hydrogen and oxygen. Example below:
