From doing a bit of digging into this myself after hearing it being promoted on the radio, I both agree and disagree. Working through the $/acre for on-site produced ammonia using locally-generated electricity (I forget if I was looking at PV or Wind, doesn’t matter) the payback period was surprisingly quick, like 2 or 3 years. One of the big reasons is that you don’t actually need a very big system; you only need on-farm ammonia a few days a year but you have all year long to harvest and store enough for those few days.
