General Motors has invested significant R&D dollars in H2 powered vehicles, to the point that some industry analysts I have read think GM put too many eggs in one basket.
Fuel cell technology will be the storage method, not pressurized tanks.
Existing LP gas pipelines are not easily converted because H2 is much "leakier" than is LP.
So, local generation makes sense. Electricity is very transportable, so using locally and remotely generated electrical power to generate H2 locally makes sense even given the ineffieciencies.
The Hindenburg Society, a group that advocates for use of H2 as a fuel has been around for years. H2 is apparently safer than good old gasoline according to tests and studies done by the Hindeburg Society. Safety doesn't seem to be the issue, economics and logistics are.
The techology to make an internal combustion engine that runs on H2 exists today, that isn't the problem.
H2 generation, storage, and transport are the technical and economic challanges as I understand it.
I'd be up for setting up an experimental H2 generator, sounds like a neat idea.
I have what was once a mill pond for a water powered sawmill on my property. I'd love to set up a little hydroplant, but the environmentalists would make rebuilding the dam next to impossible. A small scale hydro-electric plant generating H2, that'd be neat.
I'm interested in how this develops.
