Reply #6: Good idea! But hydrogen has some pitfalls that need to be resolved

[LiberalEsto]

Hydrogen, by its nature, is extremely difficult to store and transport. It can "age" the materials it is stored in, making them brittle and useless. Hydrogen is also explosive. The Hindenberg zeppelin disaster involved hydrogen, which is why later blimps used helium, a stable gas.

Research is being done into the use of carbon nanotubes to store and transport hydrogen, but there have been some worrisome findings lately that nanomaterials can cause cancers.

And there are still a lot of details to be worked out in creating a hydrogen fuel infrastructure.

This info from Australia is the most promising thing I've seen yet for creating a source of hydrogen.

I wouldn't hold my breath about converting existing cars to hydrogen power. Once again, a lot has to do with the special materials that will be needed to store the hydrogen, and I don't know if that is possible with a conventional car. It might need major modifications.
