Did you check https://farwind-energy.com/fr/ ? That's exactly what they are trying to do ! I would really like to see numbers; as elegant as it appears, I don't really think it can be very efficient.

The answer is to build enough for the average load Not really as the round trip efficiency of electricity to h2 to electricity again is only in the order of 30%. So it will be less attractive than that.

I did implement a math parser a couple of years that did JIT wasm code generation. It operated on 1d array, providing kind of numpy syntax. It achieved a very decent performance. It was quite some fun.

Capacity factor of latest floating offshore wind can be as large as 57% ( https://www.equinor.com/en/news/20210323-hywind-scotland-uk-... ). 30% is typically what you get onshore.

Finding a boat on a budget is easy. What is not is finding a harbour post to moor it. At least here in south of France, this can get really expensive and you may have to wait for years before getting one.
