摘要: Abstract This study analyses the role that renewable energy based desalination, in conjunction with improvements water use efficiency irrigation sector, can play towards securing future global supplies. It is found desalination demand by 2050 be reduced as much 30% and 60%, depending on growth rate. India, China, USA, Pakistan Iran account for between 56% 62% of demand. Decarbonising sector 2050, will result average levelised cost decreasing from about 2.4 €/m3 2015, considering unsubsidised fossil fuel costs, to approximately 1.05 most regions range 0.32 – 1.66 €/m3. Low-cost electricity, particular solar photovoltaics battery storage, form backbone a sustainable clean supply, supported measures increase efficiency. The results show untapped relationships decarbonised utilised strengthen supply decades come meet United Nations Sustainable Development Goals.
