Production of low-carbon “blue” ammonia requires the addition of a carbon capture & storage (CCS) solution to the ammonia value chain. With the prevalence of geologic storage immediately below many US ammonia production facilities, onsite co-location of CCS facilities provides a number of attractive benefits to producers looking to make their ammonia low-carbon. Onsite CCS is a proven, ready-to-execute solution (the only two existing CCS projects in the U.S. today are co-located with emitting facilities) that delivers a lower cost, lower complexity decarbonization pathway for ammonia production, while simultaneously capturing the benefits of “outsourcing” CO2 disposal.
