Cryogenic air separation is used to produce 400MTpa of oxygen, plus pure nitrogen and argon; for steel, metals, ammonia, wind-solar inputs, semiconductor, blue hydrogen and Allam cycle oxy-combustion. Hence this 16-page report is an overview of industrial gases. How does air separation work? What costs, energy use and CO2 intensity? Who benefits amidst the energy transition?
