How about we have a tech forum where we can geek out?
I follow both battery and fuel cell technologies closely. Along with nuclear and solar projects as well. I think BEVs are perfect for around the town driving, but I think FCVs will end up dominating the long distance trips. I think a BEV/FCV hybrid would be the way to go. Plug in for your commute to work, but fill up for the long treks.
Hydrogen storage is particularly fascinating because it is so difficult. But there are compounds that absorb more hydrogen by volume and by weight than liquid hydrogen.
This graph shows various compounds and their gravimetric and volumetric densities. The red lines are gasoline equivalents based on 60% fuel cell efficiency, and 30% ICE efficiency.
The problems are that these materials might take on the hydrogen too slowly, or release it too slowly, or only at high temps, or only a small percentage, or are difficult and expensive to reproduce in large quantities, etc. Various different mixtures are tried to see what works best, just like in the battery world. If one of these in the upper right of the chart becomes commercially available, then even aviation will become electric. If the hydrogen was produced via solar, it would be carbon free, and the operating costs would be less than 1/5th of what they are now.
I think this technology is fascinating. It would be cool to see it implemented before humans kill themselves off.
