No. Haber-Bosch process is very mature by now and it doesn't take much more energy than thermodynamically necessary to do so. You get there by recycling heat and reusing energy of compressed gases. The actual problem is getting that hydrogen in the first place
If you want to use hydrogen as a fuel anyway, you can add that little overhead and get fuel that you can either burn in ICE or go the whole nine yards, crack it back into elements and put that in fuel cells, and, more importantly, this comes with massive advantage of ammonia being about as easy to liquefy as propane, and we already have propane fuelled cars. Energy density is vastly higher than hydrogen this way, less than propane, sure, but it's something
Another option is dimethyl ether, but this thing needs to take carbon from somewhere, just like methanol
