Its quite a bit more than that. It takes 55kwh to crack the water to get that h2 using hydrolosis

A question becomes then if planes are 10% of us transit emissions, all other large transit 10%, and our personal cars are 45% and semis are 35%. Should we be using energy to do this? That same solar would most likely reduce emissions more if you put it directly into cars / busses / semis as battery electric. You dont have the conversion loss, and BEV is 10-15% more efficent than FCEV
