Power to Gas
Storage of intermittent renewable energy is one of the core challenges that needs to be addressed to make the energy transition away from fossil fuel work. Pumped hydro is a reliable method, but this requires the presence of mountains and valleys and these are in overpopulated Europe in short supply. Another approach is the conversion of renewable electricity into gas, like H2, CH4, CO, etc. “Power-to-gas”.
