Geothermal Energy Use in Seawater Desalination

The Earth is made up of 71% water, but the world still has water shortage, so what is the reason? The answer to that question is that 97% of the water available is salty water, and all of it has high salt content, which makes is impossible for drinking, consuming, and irrigation. The solution for this problem is desalination, it is the only way that we can get drinkable water, other than fresh resources. But desalination usually consumes a huge amount of electricity, so other sustainable sources to help in the process of desalination in a cleaner and more cost-effective way should be considered. In this work, two main technologies for water desalination using geothermal-powered systems are presented and discussed. These technologies are promising, especially in gulf region, where geothermal energy is available generously.
