Saudi Arabia Hydrogen-Powered Seawater Desalination Plant Development Feasibility Study with Water Infrastructure Forecast

Executive Viability Abstract

This feasibility study evaluates the development of a large-scale seawater desalination plant in Saudi Arabia powered exclusively by green hydrogen. Aligning with Saudi Vision 2030 and the Saudi Green Initiative, the project seeks to replace carbon-intensive thermal desalination with high-efficiency Reverse Osmosis (RO) integrated with hydrogen fuel cell technology and electrolysis. The analysis confirms high viability due to state-backed incentives, the decreasing cost of electrolyzers, and the critical need for sustainable potable water in a region with 7% annual demand growth.

## Technical Feasibility The project utilizes Proton Exchange Membrane (PEM) electrolyzers to convert solar/wind energy into green hydrogen, which is stored and utilized via fuel cells to provide a constant 24/7 power supply to a Sea Water Reverse Osmosis (SWRO) facility. This decoupling from the grid ensures zero-carbon operations. Key technical challenges include brine management and hydrogen storage density, both of which are addressable through modern modular engineering. ## Market Analysis Saudi Arabia accounts for approximately 25% of global desalinated water production. The Saline Water Conversion Corporation (SWCC) is transitioning toward privatization and sustainable energy. Market demand is driven by rapid urbanization and the expansion of mega-projects like NEOM and the Red Sea Project. Hydrogen-powered desalination offers a 'green water' premium for industrial off-takers and high-end residential developments. ## Financial Projections Total CAPEX is estimated at $1.45 Billion, covering the desalination unit, hydrogen production facility, and storage infrastructure. Revenue is generated through long-term Water Purchase Agreements (WPAs) with a projected price of $0.65 - $0.85 per cubic meter. OPEX is significantly lower than traditional plants due to eliminated fuel costs and reduced maintenance of modern RO membranes. ## Risk Assessment Primary risks include the high initial capital requirement and the technological maturity of large-scale hydrogen storage. Mitigation strategies include sovereign guarantees from the Public Investment Fund (PIF) and phased scaling of the electrolyzer farm.
