Saudi Arabia’s NEOM Green Hydrogen Project, touted as the world’s largest green hydrogen facility, has reached 80% construction completion, according to U.S.-based industrial gases giant Air Products. The NEOM Green Hydrogen project is an ambitious initiative located in Saudi Arabia's NEOM region, aiming to become a global leader in sustainable energy production. This project focuses on producing green hydrogen using renewable energy sources, primarily wind and solar power. By leveraging the region's abundant natural resources, NEOM plans to generate hydrogen through electrolysis, a process that separates water into hydrogen and oxygen without emitting carbon dioxide.

The milestone covers key project components including the green hydrogen facility itself, a wind garden, solar farm, and transmission grid. Major equipment such as wind turbines, electrolyzers, hydrogen storage units and pipe racks have been delivered and are being installed across the site, reported Offshore Energy.

The 4 GW renewable energy infrastructure powering the facility—comprising solar and wind farms—is slated for completion by mid-2026, with the first shipments of green ammonia expected in 2027.

A joint venture between ACWA Power, Air Products, and NEOM, the project aims to produce up to 600 tonnes of carbon-free hydrogen per day translating to over 1 million tons per annum of green ammonia. The ammonia will serve as a cost-effective carrier for global export, supporting decarbonization across industrial and transport sectors.

While based on established technologies, the project stands out for integrating them at an unprecedented scale. Once operational, it is expected to prevent up to five million metric tonnes of CO₂ emissions annually. Spanning more than 300 square kilometers in NEOM’s Oxagon industrial city, the facility aligns with Saudi Arabia’s Vision 2030 and the Saudi Green Initiative. It will run entirely on renewable power generated on-site.
