The gNH3 production requires a large amount of renewable energy, where the LCoA is strongly affected by the LCoE. If it is considered only a solar solution, the low Photovoltaic (PV) technology cost can achieve competitive gH2 cost. However, the industrial NH3 plant would require power stability in a 24/7 profile, and a storage solution must be included. In this case, the Concentrating Solar Power (CSP) presents an unique and promising advantage with its dispatchability to fulfill this necessity. Therefore, a hybrid CSP+PV solution can give the best cost solution power mix for the green ammonia industry.
