Neom Green Hydrogen Project Overview

The NEOM Green Hydrogen Project is built as the world's largest hydrogen facility that will produce 600 tonnes of clean hydrogen per day. It is currently under construction in NEOM, Saudi Arabia, as a joint venture by NEOM, Air Products, and Acwa Power. 

The facility will use electrolysis to produce approximately 4 GW of renewable hydrogen, resulting in the production and global export of 1.2 million tonnes of ammonia annually. This hydrogen project will avoid about 5 million tonnes of CO2 emissions annually. 

The green hydrogen will be produced using onshore solar and wind energy, with storage facilities supporting hydrogen production facilities. This makes it the world’s first commercially based hydrogen project powered entirely by renewable energy. On 2nd June 2025, NEOM announced that 80% of the construction has been completed across all its sites, including the green hydrogen facility, wind garden, solar farm, and transmission grid. 

Project Background

The NEOM green hydrogen project is part of Saudi Arabia’s Vision 2030 to build a carbon free world in the future by harnessing global energy transition. The hydrogen project was announced in 2020 by the Saudi Arabia government and it was awarded to a consortium formed by NEOM, ACWA Power, and Air Products.

In Q2 2020, the construction of the first phase of the NEOM green hydrogen project began, in which Air Products was awarded the main EPC contract to construct the plant and the sub-EPC contract was awarded to L&T (Larsen & Toubro) one of the largest construction companies in India. The funds of USD 8.5 billion were acquired from several local, regional and international banks. 

The project is under construction and is being built in multiple phases. Currently, about 80% of the construction has been completed. The construction is expected to be complete by mid-2026, and the electrolyzers and first ammonia production are expected to be delivered by 2027. This project is being built as part of the NEOM megacity near the northwestern region of the Red Sea, Saudi Arabia.

Neom Green Hydrogen Project Location

The NEOM Hydrogen Project is located in Oxagon, built within the NEOM megacity in Saudi Arabia. It is being built as the world’s largest green energy project, covering an area of 300 km².

NEOM Green Hydrogen Project Cost

The NEOM Green Hydrogen Project in Saudi Arabia, Middle East is being built at a cost of USD 8.4 billion. It received funding from 23 local, regional, and international banks and financial institutions. An exclusive 30-year offtake agreement for the green ammonia produced was signed during the project's financial close on May 22, 2023.

Technical Specifications

The NEOM Green Hydrogen Project by Air Products will use a PEM (Proton Exchange Membrane) electrolyzer supplied by Thyssenkrupp. These electrolyzers will operate with a capacity of 2 GW, making it one of the world’s largest green hydrogen production facilities.

The clean energy produced at the NEOM Green Hydrogen Project will be converted into green ammonia using the Haber-Bosch process, where hydrogen is combined with nitrogen from the air at moderately high temperature and pressure to produce ammonia.

NEOM Green Hydrogen Project Contractors  & Suppliers

Air Products is the primary EPC Contractor (Engineering, Procurement, and Construction). They are the system integrator and off-taker for the NEOM green hydrogen project under a 30-year agreement. 

Under this agreement, the green ammonia produced by NGHC (NEOM Green Hydrogen Company) will be purchased by Air Products. The sub-EPC contract has been awarded to L&T (Larsen & Toubro). ACWA Power is an equal partner, holding a 33.33% share in the joint venture with NGHC facility.

Envision Energy is the manufacturer of the wind turbines installed in the NEOM Green Hydrogen Project, which are supplied to Air Products. The PEM electrolyzer is supplied by Thyssenkrupp. 

NEOM Green Hydrogen Project Investors

In May 2023, NGHC achieved full financial close for the NEOM green hydrogen project.

NEOM Green Hydrogen Project Status 2025

On 2nd June 2025, NEOM Green Hydrogen Company (NGHC) announced that it has reached 80% construction across all its sites, including the green hydrogen facility, wind garden, solar farm, and transmission grid.

NEOM planned at Oxagon as the world's largest green hydrogen plant has completed installation, including wind turbines, hydrogen storage vessels, electrolysers, the cold box, and pipe racks. The construction of this 4 GW solar and wind power generation is expected to be completed by mid-2026. The electrolysers and the first ammonia product are expected to be commissioned by 2027.

Benefits

The NEOM Green Hydrogen Project will reduce carbon emissions by approximately 5 million metric tonnes per year by producing carbon free hydrogen using renewable sources such as wind, onshore solar, and storage facilities. 

Furthermore, the NEOM Green Hydrogen Project is aligned with the Kingdom’s Vision 2030, creating thousands of jobs and boosting local industries. Built using renewable energy and advanced technology, the NEOM Green Hydrogen Project is diversifying energy sources, leading to reduced reliance on fossil fuels. 

Summary

The NEOM green hydrogen project is built within the megacity of NEOM in Saudi Arabia. It is built at a cost of USD 8.4 billion by a joint venture of NEOM, ACWA Power and Air Products. On its successful commission, it will produce 600 tonnes of green hydrogen per day sufficient to run 20,000 hydrogen fueled buses. Additionally, it will generate 4 GW of renewable electricity from on-site wind turbines and onshore solar plants integrated with storage. 

It is built covering an area of 300 km2 of land and is in line with Saudi Vision 2030 and Saudi Green Initiative. The NEOM green hydrogen project will create about 300 on-site jobs after completion and will save up to 5 million tonnes of carbon dioxide emissions every year. Thus, NEOM Green Hydrogen project is known to be world’s largest green hydrogen plant.
