Power to X – green hydrogen for electrical energy and fuel, for production and products

Basing on the figure “Power to Hydrogen / Power to Gas”, shown by the authors at the last HTRSE conference, this time it will be illustrated, that green hydrogen - produced with renewable energy - has the potential to become a basic material in the economy at general instead of fossil one. Synergies are available. But the low price of hydrogen produced via steam reformation of natural gas prevents to reach business cases for environment friendly products as long as the European laws and regulations do not support production and use of green hydrogen for instance by a tax for CO2 emission.
