Abstract
Methods and systems for ammonia production are provided. An exemplary method includes electrolyzing water to form H2 and O2; contacting a reformer feed stream including hydrocarbons, O2 from electrolysis, and an oxidant stream including O2 and N2 to form a reformed stream including H2, CO, CO2, and N2; contacting the reformed stream with a water-gas shift catalyst to form a shifted stream including H2, CO2, and N2; separating the shifted stream to form a captured stream including CO2 and an ammonia production feed stream including H2 and N2; and reacting the ammonia production feed stream, and optionally H2 from electrolysis, to form ammonia.
