> The main downside to factobatteries is the same as for e-fuels: high capital cost due to low equipment utilization. shorter equipment life, and significantly reduced efficiency for things that require heat. A lot of processes are continuous, where the cost of stop/starting is much greater than absorbing the energy price differential. aluminium, smelting is a prime example. Yes you need kiloamps to smelt, but you also have to keep the alumina molten.
