Figure shows the breakdown of LCCO2 emissions from the WEA scheme in cases where PV power allocation to desalination is 0%, 50%, and 100%. The decreased energy for pumping water due to the difference in atmospheric pressure and the loss at the inlet/outlet is a tiny percentage of the total and almost invisible. Unless PV electricity is allocated to the ammonia synthesis mainly, a huge proportion of the energy is spent on water transport in the vertical direction, the same tendency as the sensitivity analysis results in Section 3.1. It can also be seen that the amount of LCCO2 emissions is influenced by the water transport vertically more largely than horizontally, even for very long horizontal distances of 1000 km. Therefore, the positional energy of water is essential, and the elevation of the city is more important than the distance from the coast as a factor influencing LCCO2 emissions.
