Using electrolysis to get hydrogen to make ammonia fertilizer may be an even bigger waste of energy and money than using the hydrogen as an energy “source”.
This topic usually starts talking about it in the context of what is economical or not economical.
Money is a substance the Federal Reserve creates from thin air on the basis of whimsy. It can’t possibly decide anything with physical meaning like joules.
The reason this transition isn’t happening is physics. Not money. Physics. Oil did not become oil in civilization because of conspiracy or agenda. It because civilization’s lifeblood because of physics. Energy density.
There is no escaping this. Clean vs not clean is not a factor. Earth temperature average during the Jurassic period was 83 degs F. It is currently 58 degs F. (because of the poles).
Physics always wins.
may well be. I wasn’t defending the value proposition. I was merely pointing out the fact that hydrogen is relevant to fertilizer, responding to the point that “hydrogen isn’t fertilizer”
