Fuel cells are quite efficient (much better than ICEs which waste a lot of their energy as heat). The one thing which could head off a hydrogen economy would be the development of inexpensive, quick charging, high energy density batteries. This would also be a positive development. Either batteries or hydrogen (or possibly another as yet unknown alternative) will eventually replace petroleum as a fuel - and that will be a good thing.

I know. The "inventor" and the Freeper I'm laughing at are generating H2 to burn in an ICE.

Common sense would also head off a hydrogen economy.

How will the hydrogen be generated?

and that will be a good thing.

Why?
