ACWA Power completes US$8.5Bn NEOM Green Hydrogen Facility
NEOM has officially completed the construction of its flagship $8.5 billion green hydrogen mega-project at Oxagon.
As the international community accelerates its transition towards a net-zero future, the energy sector is undergoing a profound and necessary transformation.
At the centre of this shift is green hydrogen, a sustainable fuel capable of powering industries that have traditionally relied on heavy fossil fuels. Unlike conventional hydrogen, which is extracted using natural gas, green hydrogen is produced entirely through the electrolysis of water, powered exclusively by renewable energy sources. This zero-emission profile makes it a critical asset in the international effort to mitigate climate change and restructure global energy grids.
However, the road to widespread commercial adoption is not without its hurdles.
Scaling Up and Logistical Barriers
The primary challenge facing the green hydrogen industry is the sheer operational scale required to make it commercially viable. For decades, green hydrogen has remained a boutique, experimental solution, heavily hindered by high production costs and the massive infrastructure needed to generate sufficient renewable electricity.
Furthermore, transporting raw hydrogen over long distances presents a formidable logistical barrier. The element suffers from a notoriously low volumetric energy density and requires highly pressurised or cryogenic storage solutions to move securely. To truly decarbonise hard-to-abate sectors such as heavy manufacturing, commercial aviation, and maritime shipping, developers must transition from modest pilot programmes to colossal, utility-scale operations. This necessitates immense capital expenditure, the seamless integration of sprawling solar and wind power assets, and a scientific solution to the overarching transportation dilemma.
Green Ammonia and Saudi Arabia's Vision 2030
The prevailing market solution to the export challenge lies in the synthesis of green ammonia. By combining clean hydrogen with nitrogen extracted from the air, energy producers can create green ammonia, a liquid compound that is significantly easier, safer, and cheaper to store and transport internationally. Once it reaches its destination, it can be utilised directly as a low-carbon fuel or converted back into raw hydrogen.
Against this market backdrop, Saudi Arabia is actively positioning itself as a vanguard of the clean energy revolution. Historically renowned for its vast oil reserves, the Kingdom is rapidly diversifying its economy under the Vision 2030 initiative. A cornerstone of this strategy is NEOM, a futuristic mega-city designed to operate entirely on renewable energy. Within NEOM lies Oxagon, an advanced industrial hub intended to redefine clean manufacturing and establish robust new international supply chains for sustainable fuels.
A Monumental Milestone at Oxagon
Turning this ambitious green vision into reality, a formidable consortium has achieved a landmark breakthrough. The NEOM Green Hydrogen Company (NGHC)—a strategic joint venture comprising the Saudi utility giant ACWA Power, the US-based industrial gas leader Air Products, and NEOM—has officially completed the construction of its flagship $8.5 billion green hydrogen mega-project at Oxagon.
ACWA Power Chief Executive Officer Samir Serhan recently confirmed during an earnings call with analysts and investors that the monumental facility has successfully transitioned into the commissioning stage. When fully operational, the plant will stand as the world’s largest commercial-scale green hydrogen production facility, projected to produce up to 600 tonnes of carbon-free hydrogen per day. This enormous output will then be converted directly into green ammonia for export to global markets.
The physical scale of the supporting infrastructure is unprecedented. The operation requires an immense amount of green electricity, which will be supplied by an integrated network of renewable assets. In March, NGHC reported that the project’s dedicated renewable power generation infrastructure—comprising a massive solar farm, a sprawling wind garden, and a bespoke transmission grid—had already reached approximately 95 per cent completion.
Addressing the timeline and future operational targets, the company confirmed its commitment to the scheduled global rollout. As stated in an official company update: “The project remains on schedule, with up to 4 GW of combined solar and wind power generation targeted for completion by mid-2026, followed by commissioning of the electrolyzers and first green ammonia product availability planned for 2027.”
By effectively marrying massive renewable energy generation with cutting-edge electrolysis and ammonia synthesis, ACWA Power and its partners have successfully demonstrated that utility-scale green hydrogen is no longer merely a theoretical concept.
