Hybrid membrane and thermal seawater desalination processes powered by fossil fuels: A comprehensive review, future challenges and prospects

Various hybrid desalination systems have been proposed during the last two decades to improve the produced water quality, energy efficiency, water production rate and sustainability among others, receiving therefore a rapid industrial implementation. Desalination processes are energy intensive and this energy is mostly provided by fossil fuels, especially for large scale commercial plants. No doubt, the use of renewable energy (RE) sources is a way forward to decrease the environmental and related health impact to produce and supply freshwater in remote regions with severe water shortage and an unfavourable or unfeasible connection to the public electrical grid. However, most installed renewable energy desalination plants have small capacities, yet facing several issues for long term operation. Therefore, this study restricts to…
