Transformer le surplus d'électricité ... oui ça doit exister =) ... à suivre en fonction du rendement etc... stocker de l'H2 et de l'O2 ça pompe aussi de l'énergie. La news date de janvier 2022.
La méthode:
“We use that excess electricity from renewables to electrolyze water and make hydrogen and oxygen, and then we store them separately,” Kapat says.

Later, when electricity is needed, the UCF technology combines the stored hydrogen and oxygen in a combustion chamber. The combination forms water, which heats and mixes with supercritical carbon dioxide (sCO2). Part of the closed-loop power system, sCO2 is a nontoxic, nonflammable, low-cost working fluid used to run turbine systems that generate electricity.
