A stable energy supply in the future can only be ensured with the storage of energy on a large scale. On the basis of the liquid organic hydrogen carrier system (LOHC) and with the aid of PEM electrolysis and solid oxide fuel cells, the dimensions and above all the capacity of a storage power plant to replace…
