ACME Group has announced plans to invest approximately USD 4.2 billion in the expansion of its green hydrogen and green ammonia project in Duqm, Oman, reinforcing its commitment to large-scale clean fuel production and supporting Oman’s ambition to become a global green hydrogen hub.
The investment will fund the second and third phases of the project, following the signing of an investment agreement with Oman’s Public Authority for Special Economic Zones and Free Zones (OPAZ). The expansion forms part of a broader renewable energy development program being advanced within the Special Economic Zone at Duqm.
Under the expansion plan, each phase is expected to produce around 71,000 tonnes of green hydrogen and 400,000 tonnes of green ammonia annually. Once both phases are operational, the project’s cumulative production capacity is projected to reach 142,000 tonnes of green hydrogen and 800,000 tonnes of green ammonia per year. Commercial operations for Phase 2 and Phase 3 are targeted to commence in 2030 and 2033, respectively.
The project builds upon ACME’s first phase in Duqm, which is currently under development and is expected to produce 100,000 tonnes of green ammonia annually. The overall development is set to play a significant role in advancing Oman’s national green hydrogen strategy and expanding the country’s renewable energy value chain.
According to industry estimates, the investment further strengthens Oman’s position as an emerging destination for green hydrogen investments, while supporting global efforts to decarbonize hard-to-abate sectors through the production of sustainable fuels and green ammonia for domestic and export markets.
The expansion marks another major milestone for ACME’s international clean energy portfolio and underscores the growing momentum of large-scale green hydrogen and ammonia projects across the Middle East.
