I would likely be less vociferous about hydrogen fuels if its proponents spent some time talking about how the gas is to be stored, and how it would be made safe in case of accident. That and the infrastructure for filling stations. I do find the possibility interesting, but I would like to see less "blue sky" and more facts about how it would be done (and done safely).

"I would likely be less vociferous about hydrogen fuels if its proponents spent some time talking about how the gas is to be stored, and how it would be made safe in case of accident."

OK, here's the facts on hydrogen. Hydrogen is a MAJOR industrial gas, usage of which is probably in the megatons/year category. It is routinely used from the very small scale to the very large scale. ONE company (Air Products) alone owns and runs over a thousand miles of hydrogen pipelines.

Every facet of safe usage is known and part of the established engineering literature. There is no magic needed to use it safely. It is a "known quantity" in science and engineering.

The ONLY part that is not in routine use is how one would put it into service in the hands of "non-experts" who need to fill their vehicles. One proposal is to make the process "robotic", i.e. the car and "gas pump" would be equipped with mechanisms that would make and test the "hookup" before gas is delivered.

But again, this sort of thing is well developed technology.

At one time we didn't know how to use gasoline safely, either, yet today it is routinely handled by millions of people.

The only real major unknown at this is how to produce hydrogen in the large quantities that would be needed.
