> I don't see this making any sense for large scale energy storage. Storage tanks for compressed hydrogen enjoy the square-cube law. This system doesn't store hydrogen. It stores elemental iron (produced from iron oxide, i.e., iron ore, and hydrogen from solar power splitting water into hydrogen and oxygen), and uses steam to get the hydrogen out (and convert the iron to iron oxide) only when the hydrogen is needed. |
