    The Haber-Bosch process produces ammonia from hydrogen and nitrogen gases in a globally important energy-intensive process that uses coal or natural gas as a fuel and hydrogen source. Direct electrochemical ammonia synthesis from nitrogen and water using renewable energy sources presents an alternative to the Haber-Bosch process that would be more sustainable. Additionally, the different production structure of direct electrochemical nitrogen reduction technology suggests a supply chain alternative to the ammonia industry and a method for load leveling of the electrical grid. This alternative route to ammonia from dinitrogen would require smaller capital investments than the Haber-Bosch process and would not require a fossil fuel supply. The impact of dynamic electrical power pricing is analyzed for a system that could take advantage of pricing volatility. We show that, under certain scenarios, at achievable levels of energy efficiency with a future electrocatalyst, direct nitrogen reduction would be economically competitive or advantageous compared with Haber-Bosch-based ammonia production.
