As a long term storage the idea is too expensive, in the short term hopefully Graphene - batteries will come soon.

In my opinion, only one technology is never the solution, especially for such a complex topic as energy logistics. Even from an investment point of view, it would only be speculation without a precise definition of the most efficient solution, which is not a bad thing. I just wanted to say that I do not categorically exclude such approaches just because one seems better. Our world is too complex for that. You see how now hydrogen is promoted even if it is not the most sensible. Yes for the industry but I mean in general.
