Abstract

ContextGeothermal energy is one of the most promising renewable energy sources as it is a power source that produces electricity with minimal environmental impact. It has been proven that among renewable energy sources, it is the most reliable, safe, and clean, and therefore it is used for power production, heating, and cooling. The importance of geothermal desalination is beneficial in areas lacking natural groundwater or surface water supplies. Over time, water reuse desalination can solve water scarcity and, in some countries, provides over 90 % of the total water supply. The novelty of the workThis research presents an in-depth analysis of the desalination of seawater utilizing geothermal energy as the primary resource. It will also evaluate the risks and market possibilities of the system and the constraints on further development. MethodologyThe method of geothermal desalination has also been briefly covered, along with the most common cycles of thermal desalination. These cycles include multi-effect distillation, multistage flash distillation, and vapor compression. Main results and related interpretationsGeothermal desalination technologies address worldwide water scarcity sustainably and effectively. Geothermal energy can make desalination more sustainable and environmentally friendly. Compared to conventional fossil fuel-based systems, desalination using geothermal energy can result in lower overall energy usage and CO2 emissions.
