Energy for desalination: A state-of-the-art review

The utilization of seawater for drinking purposes is limited by the high specific energy consumption (SEC) (kW-h/m3) of present desalination technologies; both thermal and membrane-based. This is in turn exasperated by high water production costs, adding up to the water scarcity around the globe. Most technologies are already working near their thermodynamic limit, while posing challenges in further SEC reductions. Understanding the current...
