The global green hydrogen industry is expanding with various large-scale green hydrogen projects. According to IRENA (International Renewable Energy Agency), hydrogen and its derivatives will fulfill about 14% of global energy demand by 2050. Consequently, IEA (International Energy Association) predicts the global green hydrogen production can reach about 38 million tons by 2030. To achieve this goal, countries around the globe are exploring new green hydrogen technologies to ramp up production at an ecomical scale.

Saudi Arabia, Australia, China, India and countries in European Union are leading the green hydrogen market with large scale green hydrogen production plants. In 2024 about 1,572 green hydrogen projects were in pipeline of which around 434 projects reached the FID (Final Investment Decision) stage worth USD 75 billion. This blog outlines some of the world’s largest green hydrogen projects. 

Top 10 Green Hydrogen Projects in the World (Ranked based on hydrogen production capacity)

Western Green Energy Hub

The Western Green Energy Hub (WGEH) is being built in the Western Australia spanning 15000 km2. It is one of the world’s largest green hydrogen hubs , which was initially planned as a 50 GW project of renewable energy from wind and solar power is now expanded to 70 GW. 

On commission in 2030, it will produce around 3.5 million tons of green hydrogen & approximately 20 million metric tons of green ammonia annually. Once fully operational, it is expected to world's largest hydrogen plant. The WGEH is built by a consortium of InterContinental Energy, CWP Global, and Mirning Green Energy Limited. In March 2025, it was awarded the "Major Project Status" by the Australian government. This will create up to 3.5 million tonnes of  green hydrogen and e-fuels every year.

The project will utilize 25 million solar panels and 3000 wind turbines for the production of green hydrogen. It makes use of advanced manufacturing methods to produce energy while also making a major contribution toward lowering the release of carbon dioxide.

CWPG AMAN Green Hydrogen Project

The AMAN project is a pact between CWP Global (CWPG) and Mauritanian government. This is a 30 GW wind and solar power to X hub developed in the Sahara Desert. Once operational, this project will produce 1.7 million tonnes of hydrogen annually and 110 TWh (terawatt hours) of electricity annually.

Apart from green hydrogen, this project can produce about 10 million tonnes of ammonia annually. The AMAN project is planned in a 8,500km2 site in the country’s northern desert and coastal regions of Dakhlet Nouadhibou and Inchiri, Mauritania.

This 30 GW (18 GW wind and 12 GW solar) green hydrogen project was initially announced in November 2021 in COP 26 in Glasgow, where CWP Global and Mauritanian government signed a MoU (Memorandum of Understanding). Mauritania and CWP Global signed a framework agreement on 22nd May 2022.

This USD 40 billion project will include 975,490 hectares of onshore wind and solar energy generation including its associated infrastructure, desalination, electrolysis and green ammonia generation facilities and a marine export facility. 

RSK was assigned preparation of screening report in initial stages of projects to identify the risks, challenges and opportunities in the project. On 14th March 2025, CWP Global announced it has completed Geological, Geotechnical, Hydrogeological and Bathymetric Studies (feasibility study) for the AMAN green hydrogen project. Once operational, the output will be three times higher than Morocco's annual energy consumption.

Australian Renewable Energy Hub (AREH)

The Australian Renewable Energy Hub is set to become one of the largest renewable energy hubs in the world, developed it multiple phases it is planned with a 26 GW generating capacity from wind and solar power which is equal to 90 terawatt hours per year. This project is developed by a joint venture of bp, InterContinental Energy and CWP Global. bp will be operator of this project with a major stake.

The partnership in joint venture is as follows:

Once operational, it will produce 1.6 million tonnes of hydrogen or 9 million tonnes of green ammonia per year. It planned across 6,500 square kilometres in the Pilbara region of Western Australia. The project is being built in three phases, in phase 1, renewable energy infrastructure of up to 1 GW will be developed and delivered to Port Hedland and Newman through Pilbara Green Link common use transmission network that will be used to generate green hydrogen. 

In phase 2, additional renewable (solar & wind) infrastructure wil be built along with construction of electrolyzers. Under phase 2, desalinated water will be combined will renewable energy to power electrolyser for electrolysis and produce green hydrogen. the desalinated water will be supplied through pipelines from Port Hedland.

Phase 3 the green hydrogen produced will be used to produce green hydrogen derivates such as ammonia production and storage at Boodarie Strategic Industrial Area near Port Hedland. The project is expected to be commissioned by 2030. The early exports is expected in 2028-29. The project cost is estimated as AUD 30 billion (USD 20 billion).

BrintØ Green Hydrogen Island

The BrintØ green hydrogen island is a 10 GW project built near the North Sea in Denmark. It is built on a sandbank covering 20,000 km2 at the Danish part of Dogger Bank. The BrintØ green hydrogen island is one of the upcoming green hydrogen project in Europe which is being developed by CIP (Copenhagen Infrastructure Partners), which will produce about 1 million tonnes of green hydrogen on its commission in 2030.

This project will consist of offshore wind, Power-to-X facilities, artificial island and hydrogen pipeline. The green hydrogen produced from this plant will be to northwestern Europe in countries like Germany, Netherlands and Belgium. The BrintØ green hydrogen island will likely fulfill 7% of Europe’s hydrogen demand by 2030.
