Addis Energy is scaling a new ammonia production pathway that revolutionizes the century-old chemical production process. By targeting iron-rich resources in the subsurface, Addis is forging a new method for chemical synthesis: injecting engineered fluids that harness the chemical & thermal potential of the earth to produce ammonia. This transforms ammonia synthesis into a net energy positive process and enables producing ammonia cheaper than traditional methods.
