Yeah, green hydrogen is not coming to the rescue. It will be a good alternative fuel in the future when green electricity is in abundance.

I say a couple things off on the schematic. First why vent the oxygen. There is already a market for oxygen, but I guess it would be saturated in any situation where there is large scale green hydrogen production? Second why do you rectify the power, if the power is from photovoltaic solar it is already direct current? Third, why the circulation pumps in the water circuits, yes, water needs to be added but why circulated?
