I had a very short back and forth with someone here. One thing makes you wonder about another.
You calculate the cost of manufacturing hydrogen from water to feed into a the Haber-Bosch process to produce ammonia. All you are doing is replacing the existing steam reformer with an electrolysis plant.
But the what if is what if you can take a further step and directly create amino acids instead of ammonia. You go why do that. The answer is an acre of solar panels produces 25-50 times more energy than corn.
