Sensitivity analyses are performed for the cases where all PV power is allocated to desalination (Fig. (a)) or ammonia synthesis (Fig. (b)). The influential parameters are increased or decreased by ±1%. The values in Section 2.2 are employed for each parameter. The CO2 emission coefficient is assumed to be that of natural gas for electricity derived from fossil fuels. As the parameters not specified in Section 2.2, the elevation is considered to be about 800 m, which is the average elevation of the earth, and the distance from the coast is 200 km, referring to the Suez Canal (193 km), one of the famous canals in the world.
