Physics, Astronomy & Cosmology / How (in)effficient is electrolysis for storing energy?
« on: 10/04/2019 11:39:47 »
I've heard suggestions that hydrogen cars are the future. More generally, power stations could electrolyse water into hydrogen into hydrogen and oxygen when demand is low and burn them to produce electricity when demand is high. So how much energy is lost in this cycle as a percentage? Does anyone know the cost of the extra equipment needed?
