Here's a fuel cell. It's about the right capacity for a car, assuming you have a serious battery as well. That is you'd be running a hybrid BEV HEV.


Their pricing seems pretty consistent, about $4500 per kW. Those of you with EVs can post an average power requirement, 6 kW is a sustained cruising speed of perhaps 20 mph in a Tesla, but with sensible design (as in the EV1) could be much faster, 50 mph. GM>>Tesla

Reaction Engines unveils low-carbon spin-off for SABRE technology
5 Nov 2021

Reaction Engines is hopeful that newly unveiled technology which uses its heat exchanger system to allow regular jet engines to burn ammonia – producing zero carbon emissions – could enter service within a decade.

another day in paradise, or is paradise one day closer ?
 
A full Hydrogen economy is crazy, but a lot more hydrogen makes a lot of sense.
How else do you store solar and wind power?
You had might as well run it through electrolyzers and make H2 and O2.
You can control NOx by using EGR. I have seen demos on a heat treatment furnace that used O2, H2, and CO2 in the combustion.
The water was condensed and the CO2 was recirculated.
And then there are fuel cells. When you don't have to make them light weight or crash resistant they are a lot less cost.
