Around 40% efficiency?
I was under the impression that somewhere around 60% was available OTS, with 90% possible with more expensive systems. I could check...

If you get the chance, I'd be curious -- my numbers are somewhat old.

After a quick Google search...
It seems large commercial alkaline hydrolysis units are around 65-70% efficient. Electricity costs seem to be about 70-80% of the hydrogen production cost.
Commercial PEM electrolysers are apparently slightly less efficient at the moment but are promising to soon reach 80-90% at pressures in the
10-50 bar range. PEM fuel cell research has been aiding development.Norsk Hydro seem to be one of the main leaders in the industry.
