You should look into what they are doing in Iceland. Their target is to
have only hydrogen-powered vehicles on a fairly short timescale. They
already have many hydrogen filling stations around the country. I
believe they have solved many of the practical problems so it's time to
learn from them!

Iceland is a very special case. Things that make economic sense in Iceland
may not make any sense anywhere else.

No, there is nothing in Iceland that is fundamentally different from
anyplace else.

Iceland has abundant geothermal energy as a natural resource, unlike any
place else on the planet. From geothermal energy, they can make cheap
electricity, which they can use to hydrolize water into H2 and O2.

New Zealand, Japan, USA and Russia are among many countries that have
geo-thermal resources that far exceed those of Iceland.

The other side of the economic equation is that Iceland has no domestic
petroleum resources. Every drop of gasoline must be imported.

That applies to most countries in the world, Iceland is the rule rather
than the exception.

Cheap electricity and no domestic petroleum is exactly the economic
environment which would make H2 powered cars start to make sense. Such an
economic environment exists in very few places in the world.

It may not apply to the USA but it applies to many countries other than
Iceland.
