Saudi Arabia's Green Hydrogen Plant Enters Commissioning Phase

The NEOM Green Hydrogen Company has reached a milestone with the commissioning of its $8.4 billion facility at Oxagon, Saudi Arabia. Designed to produce up to 600 tonnes of carbon-free hydrogen daily, the site will be the world’s largest green hydrogen plant once it reaches full capacity. Commercial production is scheduled to begin in 2027, and with construction in its final stages, recent updates indicate the project is nearing completion.

The project relies on a mix of solar and wind power, utilizing up to 4 GW of renewable energy to generate hydrogen. This is then converted into green ammonia for export, providing a fuel source for industries that cannot easily switch to direct electricity. By focusing on sectors like heavy industry and transportation, the facility aims to lower carbon footprints in areas where traditional energy has long been the standard.

The company itself is a joint venture between ACWA Power, Air Products, and NEOM. Much of the recent work has involved integrating wind and solar farms into a reliable transmission network; by March 2026, these renewable assets were reported to be approximately 95% complete. The project has now moved into a commissioning phase that includes energizing the site and preparing the electrolysers needed for production.

The project fits into a wider strategy to diversify Saudi Arabia’s energy mix and reduce its reliance on fossil fuels. In addition to its environmental goals, the facility supports the local economy through job creation during its construction and eventual operation. It also establishes a pathway for the export of green ammonia, aligning with international efforts to adopt cleaner energy alternatives.

Looking toward 2027, the plant is expected to become a central part of the international shift toward sustainable energy. As the commissioning process continues, the project will meet further operational milestones on its way to full capacity. Its development serves as a model for future green hydrogen initiatives, illustrating the potential for renewable energy to meet global demands.
