Saudi Arabia’s NEOM region is constructing a $17 billion green hydrogen facility, set to be the world’s largest when operations begin in December 2026. The project features a massive 2.2 gigawatt electrolyzer system powered by renewable energy, capable of producing 2.5 billion kilograms of green hydrogen annually. Located within Oxagon and spanning 300 square kilometers, this game-changing facility will save five million metric tonnes of CO2 emissions yearly. The project’s ambitious scope promises transformative impacts across global energy markets.

The world’s largest green hydrogen facility is nearing its final stages of construction in Saudi Arabia’s NEOM region, with completion rates hitting 80% by June 2025. The landmark project, spanning over 300 square kilometers within Oxagon, represents a $17 billion investment in sustainable energy infrastructure and is scheduled to commence operations in December 2026.
At the heart of this groundbreaking facility lies a 2.2 gigawatt electrolyzer system, powered exclusively by wind and solar energy. The plant’s sophisticated electrolysis process splits water into hydrogen and oxygen without generating carbon emissions, establishing new benchmarks for clean energy production. The incorporation of cutting-edge storage solutions and transport systems guarantees seamless supply chain operations. The project aims to save five million metric tonnes of CO2 emissions annually through its innovative processes.
The facility’s production capabilities are particularly impressive, with annual output targets exceeding 2.5 billion kilograms of green hydrogen. This substantial capacity positions NEOM as a pivotal supplier for global industries shifting to sustainable energy sources. The produced hydrogen will be converted into green ammonia and sustainable fuels, serving aviation, shipping, and heavy industrial applications. The project’s innovative technology has achieved a remarkable load regulation capability between 20% and 110%. The facility’s success demonstrates the potential of regenerative braking systems in maximizing energy efficiency across industrial operations.
NEOM’s green hydrogen facility will produce 2.5 billion kilograms annually, transforming global energy supply chains through sustainable fuel alternatives.
This ambitious project has already catalyzed significant economic development in the region, fostering growth in adjacent sectors such as equipment manufacturing and clean fuel logistics. The initiative strengthens Saudi Arabia’s position in the global energy market while reducing dependence on traditional fossil fuel exports.
The project’s scale and sophistication have attracted international attention, competing with other major initiatives like Western Australia’s WGEH and Egypt’s recent $17 billion green hydrogen venture.
The NEOM facility’s advanced infrastructure leverages the region’s abundant solar and wind resources to maintain continuous production cycles. Its geological storage capabilities and sophisticated delivery systems guarantee reliable year-round hydrogen supply to clients across multiple continents.
As the project approaches completion, it stands as a demonstration of the viable scaling of green hydrogen production, marking a significant milestone in global decarbonization efforts.
Frequently Asked Questions
How Will Local Communities Benefit From Employment at the Green Hydrogen Hub?
Local communities will experience significant economic benefits through over 21,000 direct jobs by 2027, with median wages exceeding local averages.
The hub’s operations will stimulate local supply chains and service industries while driving investments in workforce training programs.
Employment stability is enhanced through long-term project timelines and union partnerships, while increased household incomes contribute to expanded tax bases for public services.
What Safety Measures Are in Place to Prevent Hydrogen-Related Accidents?
The facility implements multi-layered safety protocols including hydrogen-compatible materials to prevent embrittlement, continuous gas detection systems, and automated emergency shutdown procedures.
Advanced monitoring systems track potential leaks, while modular construction separates high-risk zones. Regular maintenance checks, rigorous staff training, and adherence to ISO and NFPA standards guarantee operational safety.
Ventilation systems and spatial separation effectively disperse any accidental hydrogen releases.
How Will the Hydrogen Be Transported From the Facility to End Users?
The hydrogen will be distributed through a multi-modal transport network combining dedicated pipelines, specialized trucks, and chemical carriers.
Pipeline infrastructure offers the most efficient delivery method for local distribution, while cryogenic tanker trucks provide flexibility for regional transport.
For international markets, the hydrogen will be converted to liquid form or chemical carriers like ammonia, enabling cost-effective shipping across long distances.
What Happens to Excess Hydrogen Production During Low Demand Periods?
Excess hydrogen production is managed through multiple storage pathways.
The gas can be compressed and stored in specialized tanks or underground salt caverns at pressures up to 700 bar. For large-scale storage, liquefaction at -253°C provides a dense storage option.
Additionally, excess hydrogen can be blended into existing natural gas infrastructure or stored in metal hydride systems, which offer lower pressure storage alternatives.
Will the Project’s Water Consumption Affect Local Water Resources and Supplies?
The project’s water consumption could impact local resources, particularly in water-stressed regions where aquifers are already declining by 3 feet annually.
While green hydrogen requires 20-30 liters per kg, including processing losses, proper mitigation strategies can minimize effects.
Using treated wastewater or desalinated seawater, combined with efficient process design and strategic sourcing, helps reduce freshwater demands.
Additionally, replacing water-intensive agriculture with hydrogen production may result in neutral net consumption.
