Özet
Wind-powered desalination is an attractive and sustainable method for providing potable water in isolated arid and coastal zones and islands. In this study, a techno-economic analysis of a wind-powered small-scale seawater reverse osmosis system (WP-SWRO) is presented. Levelised unit costs for electricity and water (LCOE and LCOW) were estimated for Gokceada Island, Turkey. The energy requirement of the system showed that water can be produced at a cost between US$2.962 and US$6.457 $/m(3) for all wind turbines (with rated capacities ranging from 6 kW to 30 kW) at various discount rates when considering off-grid operations. For a grid connected-wind turbine system, the levelised cost of water was predicted to be in the range from US$0.866 to US$2.846/m(3). The levelised costs of electricity are predicted to be US$0.077 to US$0.155/kWh for an 8% discount rate using a 30-kW wind turbine based on the turbine-specific cost. According to the results from an emission reduction analysis, using a 30-kW wind turbine for a reverse osmosis system permits a reduction of 80.028 tonnes of CO2 annually. The results show that wind-powered potable water production is economically and technically reasonable for the site. (C) 2015 Elsevier B.V. All rights reserved.
