7. The steam process generates H2 and CO.

Of course, CO is poisonous, but that isn't the big problem.

Like all molecular hydrogen generation schemes, it takes more energy to generate molecular hydrogen than is usable in burning it.

A hydrogen economy is a thermodynamic nightmare. The only way it makes any sense whatsoever is if the power comes from non-fossil fuel renewable sources (wind, solar, etc.). At least one could then argue that hydrogen could offer an energy storage medium as well as a fuel (depending on surpluses). Otherwise, hydrogen offers no benefit (other than spacecraft).

Thanks for your responses.
