For 100 years, we have made ammonia with the Haber-Bosch process, almost always using a fossil fuel feedstock. Recently, though, government policy, academic innovation, commercial opportunity, and human morality have combined to spur the development of new, “green” ammonia manufacturing processes: sustainable, low-carbon technologies. These new synthesis methods augur a future in which, instead of the single, over-riding drive toward the economies of scale associated with Haber-Bosch, an array of different feedstocks, uses, and business models will support a multiplicity of competing technologies serving multiple markets. This presentation aims to introduce the factors affecting the appetite for commercialization and adoption…
