Haber-Bosch require continuous input of hydrogen, but aside from that it is a net source of power. The reaction is exothermic and can provide more than enough work to drive compressors that pressurize the reactants.

Is that true in practice or just in theory?

		Looking more closely, it's not true at all. So ignore what I wrote. I was confused by compressors being driven by steam from the SMR plant that made hydrogen from natural gas.

TIL the Red Pyramid looks remarkably like the Haber-Bosch ammonia production process. And the word "Amun" is the etymological root of the word Ammonia.
