- moneytide1 7y agoMusk has said that hydrogen is foolish. I can understand that angle, because the concussive blast from compressed hydrogen ignition would be more dangerous than a lithium fire. But a hydrogen economy feels like it could work when scaled up. Somehow it feels practical as the most abundant element in the universe, with high energy density. Lithium/cobalt reserves are limited, though recycling measures might could solve that problem. Platinum-group element coated electrodes powered by ~25 year life spans of cadmium/tellurium solar cells (or Perovskite, and many others I'm sure, but Cd/Te is the one I've deployed en masse personally) would allow for low maintenance hydrogen generation and a shift away from natural gas sourcing. Nafion is necessary for the fuel cells themselves but I'm not sure about the production process behind that.
