If you have a solution that includes battery for daily storage and hydrogen for long term, it's not clear where you can fit intermediate term storage. That intermediate term storage will need to be more economical than just increasing a bit the hydrogen capacity. Right now we smooth the peaks using "peaker plants", i.e. turbine engines that burn natural gas. Those can be converted to burn hydrogen. You then need the intermediate term storage to be cheaper than the cost of storing some extra hydrogen, but that seems to be extremely unlikely.
- ncmncm 4y agoThere are plenty of storage options besides batteries and hydrogen. Almost all will be cheaper than hydrogen, one way or another. Hydrogen is expensive but has unique virtues for specific cases. E.g., liquified, it is perfect aviation fuel. It is necessary input for synthesizing ammonia and hydrocarbons, and numerous other chemicals and industrial processes. But it is expensive, difficult, and dangerous to handle, so you don't when you can avoid it.
