摘要: Abstract This study demonstrates how seawater reverse osmosis (SWRO) plants, necessary to meet increasing future global water demand, can be powered solely through renewable energy. Hybrid PV–wind–battery and power-to-gas (PtG) power plants allow for optimal utilisation of the installed desalination capacity, resulting in production costs competitive with that existing fossil fuel SWRO plants. In this paper, we provide a estimate cost 2030 demand electricity generation an optimised local system configuration based on hourly temporal 0.45° × 0.45° spatial resolution. The capacity required is estimated about 2374 million m 3 /day. levelised (LCOW), which includes production, electricity, transportation storage costs, regions 2030, found lie between 0.59 €/m –2.81 €/m , depending resource availability transport sites. 9790 billion € initial investments. It possible overcome supply limitations sustainable financially way.
