Well, yeah, the hydrogen solution to build out renewable overcapacity and storing production surplus as green hydrogen in natural gas caverns is dead in the water. So private households better start budgeting for sodium-ion backup for hybrid solar inverters which are island and black start capable, for when planned load shedding events start.
You need a buffer with at least 60 TWh in case of Germany. There is no economic electrochemical energy storage system for that capacity.
The easy solution is to just make green hydrogen. It’s an already solved problem, lacking only political will.
That’ll teach them to plan ahead!
