Yes, but what is the source of the electricity? This is one of the important
questions! Right now in the US coal produces close to half of all our
electricity. It makes no sense to burn more coal and petroleum to produce
electricity and then throw away a good portion of that energy to produce
hydrogen. Even if nuclear power was used to produce hydrogen, it still
wouldn't make sense.
