The article 4K8KW10 linked to stated that the current offshore wind capacity (theoretical maximum, assuming perfect conditions) of the USA is 50MW. Wikipedia says it's 42MW. https://en.wikipedia.org/wiki/List_of_offshore_wind_farms_in_the_United_States CNBC says it's 30MW. https://www.cnbc.com/2019/12/13/us-has-only-one-offshore-wind-farm-but-thats-about-to-change.html Wikipedia includes the 12MW offshore wind farm that the CNBC article says is due by 2022. Maybe it was finished early. I think you might well be right, but I hope something less wasteful can be devised. Hydrogen is a very bad choice for energy storage, but it might be the only scalable option. Hopefully not, but it might be.
