I see there is High-temperature electrolysis which is a whole different animal than room temp electrolysis.

I want to know if electrolysis of lukewarm water will behave much differently. My guess is that the water molecules can more easily disassociate.

State-of-the-art electrolysis performs at ~75% energy efficiency. What would be the energy efficiency performed on lukewarm, or hot water?

  • $\begingroup$ Majority of energy loss is due overpotential ( higher then theoretical electrolysis voltage is required ), that may get lower at higher temperatures - just guessing. $\endgroup$
