This chapter determines
the cost of desalination powered by 100% renewable energy power plants and demonstrates
how and why renewable energy powered desalination is a lucrative option to meet
the future global water demand. The global desalination demand by 2030, based
solely on water stress and water demand is estimated. Using the respective 2030
costs of renewable energy power plants, storage and seawater reverse osmosis
plants, the levelised cost of electricity and water is found. The optimal
renewable energy power plants are comprised of solar photovoltaics and wind
power plants, balanced by battery and power-to-gas storage. The global levelised
cost of water range, including costs for water transportation, is found to be 1
€/m3 - 2 €/m3. Meanwhile, the costs of fossil powered
desalination plants today, excluding water transportation, is said to be in the
range 0.6 €/m3 – 1.9 €/m3. Thus renewable energy powered
desalination, explained through several figures in this chapter, can soon
become a cost competitive option to satisfy global water demand.
