re: #380 LudwigVanQuixote

Okay that is about what I thought. As I understand they still take more power to start and run than they get out, falling short of break even. Maybe that can be described to me as a %?

Where I work we use a lot of hydrogen. Maybe 36 of the large size tanks from the supplier a week. I have done a ton of reading on hydrogen combustion etc. I know it takes more energy to split water than you get out when you reburn the gases. Short of break even, right?

My point is which “break even” is closer to practical, given the benefit of zero carbon heat.
