Power-to-X (PtX) also Power-to-Anything) is the general term for processes that convert electrical power into fuels (Power-to-Gas, Power-to-Liquid), raw materials for industry (Power-to-Chem) or other energy forms. To make PtX products, pure hydrogen is first obtained from the source products – power and water – by electrolysis. As the first PtX product, hydrogen is the basis for all other products. By adding CO2 or other carbon compounds, it is possible to produce further synthetic energy sources and chemical base materials such as methanol and kerosene. This process is only carbon neutral if the electricity is generated from renewable energy sources and the CO2 is removed from the atmosphere (Direct Air Capture) or if it is based on non-food crops. If this is the case, the PtX products are considered ‘green’. Key Findings Background China, with a total of 10.5 Gt of CO2 in 2018, is the world’s biggest emitter of…
