Feasibility Analysis of Integrated Power-to-Ammonia Processes Employing Alkaline Electrolysis and Air Separation

Abstract

This study used process simulation to assess the overall economic feasibility of a hydrogen energy system involving a power-to-ammonia process as a transportation energy source. While the relevant individual processes for the overall energy system have already been used in the chemical industry, it is financially important to approach them in a holistic simulation framework. According to the proposed simulation, the ammonia and hydrogen production costs were 288.3 $/t and 5.43–6.13 $/kg, respectively. The results could motivate further studies on accelerating the implementation of renewable energy systems to mitigate climate change.
