Here I think "solid state" referes to the technique of storing H2 based on reversible metal hydrides. This offers several benefits over other means of storing hydrogen. Reversible metal hydrides operate at low pressure compared to compressed hydrogen and do not require to be kept at the cryogenic temperatures similar for liquid hydrogen storage. So, typically, this requires less energy.

How do they plan to store solid H2? Compressing and freezing H2 until its solidification demands too much energy. Or have I misunderstood, and "solid state" refers to the storage technology of liquid H2?

Since the technology used for production of hydrogen is electrolysis, the cost of generation would be substantially high compared to the other technologies used for hydrogen production, such as generating the same from hydrocarbons, natural gas etc. But the good thing is that the electrolysis does not emit any CO2. In an article, I saw the cost as ~£7-16//GJ (~$40 - $88/MWh?) for this technology.

Not sure how much each will ultimately cost, but it would interesting to see how it compares to one of the 2.3MW windmills. 39MWh seems like a small amount (less than 1 windmill's 24 hour output).

Of all the exhibits in the Pre-Apocalypse Era Museum, Breek was always in awe of the unearthed details and true-to-scale reproduction of a technological creation space that the long gone humans had once inhabited.
