Hydrogen is one type widely used gas. It is a reagent used in many industrial sectors, like chemicals, textile fiber production, glass manufacturing, electronics and metallurgy. Meanwhile with the rapid growth of application of fuel cell, application of hydrogen is enhanced accordingly since it makes it possible to produce electricity directly onboard electric vehicles.
Nowdays most hydrogen is produced from fossil fuels, especially natural gas. However green hydrogen which is produced from water is playing a more and more important role. Electricity from the grid or from renewable sources such as wind, solar is used to produce hydrogen. Three is no carbon emmision in the entire production process of green hydrogen.
