@WolfgangFeist@hessen.social I remember hearing you say that Hydrogen was a good solution for seasonal energy storage. This was about 15 years ago. Are you still of that opinion? I have never been able to get enough trustworthy data on long term storage leakage rates, energy requirements, etc. to be able to form a opinion that I have credence in.
Thank you kindly.

@GreenFret@mstdn.plus Did I? I was always aware that H2 is difficult &expensive to use it for a large amount of SEASONAL storage. What I recommended (still see as part of a long-term solution): Synthesize CH4 from green H2 &CO2. That's the cheapest &most efficient solution for SOME seasonal storage(systems already exist!). It can only be a small part: gas turbine backup for winter load in "dark lulls" (about 25% of cont. gas storage; still expensive - but the cheapest of even more expensive solutions).
