so what is the actual efficiency now - ie what is the energy content of the h2 produced, compared to the energy input??

- Beltiras 7y agoSibling comment has the info. This is not an increase in energy efficiency just conversion efficiency. You pump in more amperes over the same voltage and manage to split twice the amount of water with the same size array. Still great thou. Anything that reduces the infrastructure needs to produce H2 is a good thing.
- jacknews 7y agothanks, and in fact the wikipedia entry for electrolysis also has lots of interesting info. It seems efficiency is between 70-85% depending on method. Interestingly it seems there is potential to be >100% electrical efficiency if the water is also heated. I can envisage concentrated heat-and-PV electrolysis plants.
