Danish renewable energy developer GreenGo Energy and Hamburg-based energy trading company Select Energy have entered a strategic partnership to jointly develop and secure offtake to “Megaton Moon”, a commercial scale renewable ammonia project in Mauritania. This comes months after GreenGo Energy Group signed an agreement with Mauritanian authorities for the development of renewable ammonia, marking its first such project on the African continent.

Powered by off-grid wind and solar energy, the Megaton Moon project will be a commercial scale renewable ammonia facility located 20 km south of Nouakchott, Mauritania’s capital and port city ideal for exports to demand centers. The facility will use desalinated seawater for electrolytic hydrogen production and air separation for nitrogen production. The ammonia produced from the facility will target the fertilizer, refineries, petrochemicals, transportation, and power generation industries.

Phase one of the triphasic project is set to come online in 2031 and will produce 355,000 tons per year of renewable ammonia, featuring 500 MW of electrolyser capacity powered by wind and solar energy. The FEED for this phase of the project is expected to be completed by 2027, with FID targeted for 2028. Phase two will see the facility expand to a total capacity of up to 1.7 million tons per year, with over 2.5 GW of electrolyser capacity. In Phase three, the project will have an increased capacity of 4 million tons annually, subject to additional land acquisition and market demand.

Acting as co-developer and offtake partner, SELECT will focus on ammonia export facilities, drawing from its expertise in commodity trading and logistics. It will also oversee the long-term marketing, offtake agreements, transshipment, distribution and financing options. The developers also intend that the renewable ammonia produced at the facility will be compliant with all European regulatory and technical standards.

We are thrilled to partner with SELECT on this transformative project. Megaton Moon represents a bold step toward global decarbonization and SELECT’s expertise in energy trading and logistics and market access will be instrumental in realizing its full potential.

Möhring Energie Holding: land allocation agreement for renewable ammonia development in Mauritania

The Mauritanian government has also signed a strategic framework agreement with German renewable energy developer Möhring Energie for the development of a large-scale industrial plant for renewable hydrogen and ammonia production.

The agreement includes the allocation of 500 km² of land in the west of Nouadhibou (a port city in Northwestern Mauritania), with potential for expansion to 1,600 km². The area offers globally competitive solar and wind energy potential and for the production of renewable molecules. Möhring Energie is developing the NAYRAH project which, from 2029, intends to produce up to 140,000 tons of renewable hydrogen and 400,000 tons of ammonia per year, powered by 1 GW electrolysis capacity.

The project will be implemented in multiple phases –an initial electrolysis capacity of about 100 MW which will be gradually scaled up to about 1GW. The project intends to use desalinated water for hydrogen production.

We are proud to be the first German company to enter into a strategic partnership with Mauritania to develop a large-scale PtX project. Mauritania has excellent conditions for generating wind and solar power – the basis for globally competitive green molecules. We would particularly like to thank the Mauritanian Ministry of Energy for their professional and solution-oriented cooperation.

Other renewable ammonia projects in Mauritania include the flagship AMAN project by CWP which plans to generate about 10 million tons per year of ammonia at full capacity, and Hynfra’s 100,000 tons capacity per year project near the capital Nouakchott. In October this year, the country launched its national green hydrogen policy, the Green Hydrogen Code, consolidating its regulatory and policy framework to support the burgeoning industry.
