Ok so the plan is to ignore actually feasible options to make transport carbon neutral and light dollars on fire researching hydrogen to maybe make nitrogen?
> to maybe make nitrogen
Ammonia Fertilizer is NH3. So that's 1x N2 + 3x H2 == 2x NH3, if I'm getting my chemistry correct.
But not "maybe", we are doing it, and we *MUST* do it. One of the biggest uses of fossil fuels in our life is our nitrogen fertilizer system. Decarbonizing our fertilizer is as big and important a goal as decarbonizing our transit.
And if H2 is useful for transit, then doubly so. We can use H2 for transit and then use H2 + N2 == Fertilizer and solve both at the same time.

You can't use batteries to make Ammonia / Fertilizer. So we're going there anyway with regards to our "tech tree". Might as well experiment and see how feasible transit is.
