The siren-like songs and the fairy tales of full electrification. - The sustainable energy transition links the electricity sector with heat, gas products and fuels. Hydrogen is the link with Power-to-X.

The siren call for full electrification lures people in with the simple and convenient-sounding claim that we only need to be able to provide enough renewable electricity and all energy issues will be solved, including mobility. However, even if the electrical grid is expanded up to a hundredfold, the systems generating the electricity would still have to be regulated to protect the grids from overload, because only as much electrical energy can be fed into the electrical grid as is being taken from the grid elsewhere at the same time. The enormous amounts of energy in the terawatt range that are to be generated by the planned wind turbines, which will then be stored by which technical solution, are being concealed. In the gigawatt to terawatt range, we really no longer need to talk about storage with batteries alone.
