1. Hydrogen is usually made from Natural Gas, which is not a clean fuel.

It's always misleading when they say the only emissions are water vapor.

While true at the point of use, it is not true at the point of production.

Hydrogen is not a source of energy; it is an energy carrier. And it takes more energy to create than it provides, in many cases.

It will only be as clean as the means of production, compression, transportation, etc.

I would think that electric rail would be more efficient and cleaner.
