This paper explores the feasibility of utilizing natural oceanic forces, particularly hydrostatic pressure, for zero-energy seawater desalination. As water scarcity becomes an increasing global challenge, innovative solutions are needed to reduce energy consumption and environmental impacts. Traditional desalination methods, such as reverse osmosis, require substantial energy input due to the need for high-pressure pumps. This study proposes an alternative approach by harnessing hydrostatic pressure at significant ocean depths to drive the desalination process without mechanical pumps. The research conducts a comprehensive feasibility study that examines various oceanic factors such as water density, salinity, temperature, marine currents, and local gravity effects. The study evaluates pressure variations at different depths, exploring how natural forces can be harnessed to reduce operational costs and improve sustainability. While challenges remain, such as harsh marine environments and the complexity of deep-sea installations, the findings suggest that using natural pressure forces has significant potential to transform seawater desalination into a more sustainable, cost-effective solution.
