Suffice it to say that you've been led astray by the hype about hydrogen.

The reality of hydrogen is that it's a global warming problem on the scale of all of aviation today and it's a greenhouse gas with 13-37 times the potency of CO2, it leaks as it's the smallest biatomic molecule in the universe and it must be stored at very high pressures.

It's inefficient and ineffective as an energy store, not a wonder molecule. It's shortcomings cannot be overcome by engineering and scaling, as they are fundamental properties of the molecule.

Your assumptions that I don't know what I'm talking about and haven't done the research, and that you do know and have done your research are both incorrect.

For some context, I would suggest reading the following pieces I've published on hydrogen.
