That is a very exciting development, thanks for that Scott, it will be cool to see where it goes.

But it is also worth noting that when we sign energy, the efficiency of standard electrolysers is not the problem it was perceived to be before we signed the energy.

Using negative energy more efficiently helps us reduce the damage done by negative energy use, hence why we might aspire to "Net Zero" but use of any positive energy at all is still something that does the opposite of negative energy, reversing some of the damage done, easily taking us "Net Positive".

So we should not worry so much about efficiency in positive energy use, if the energy costs nothing, why worry if some is wasted?

It does have a cost in extra real estate needed for panels, but, if every community already has enough real estate to supply their energy needs with current technology including hydrogen, the only thing that can be gained by better efficiency is more hydrogen from the same real estate, which might be useful to sell I guess, but the real question is; does every community have the real estate it needs to supply its own energy needs with current technology?

The real answer to that will only be found by doing the work of implementing in all places needed, but on the community use cases I've looked at and modeled, including my own residence which is a flat in a town centre block of 64 flats, I believe we have the real estate to do. I think folk will get very creative with available real estate, to do what is needed.
