A German-based startup, a leading company in the renewable energy sector, has unveiled its plans to venture into Mexico by constructing a renewable ammonia production facility.

The plant, which will be known as the Marengo project, will be a 200MW renewable ammonia production plant in Campeche, Mexico, with an initial production capacity of 180,000 tonnes of renewable ammonia annually.

To cement the plan, Hy2gen has revealed that it has signed a cooperation agreement with local development partners.

The agreement was signed by Angelica Lara Perez-Rios, Campeche’s minister of environment, biodiversity, climate change, and energy, and the company’s cooperation partner, entrepreneur Ralph Wegner, representing MexCo, as well as representatives of GIZ Mexico (Cooperacion Tecnica Alemana), part of the German Agency for International Cooperation (GIZ).

The signing, which was publicized on Linkedin by Hy2gen, was accompanied by Campeche Governor Layda Elena Sansores and German Ambassador in Mexico Wolfgang Dold.

This will allow it to conduct feasibility studies and FEED studies where they will collect essential construction data and information on the operation of the production plant.

The studies are expected to be completed in roughly 24 to 36 months and followed by the construction phase of the plant, which will then begin, with production expected to start by the third quarter of 2028.1

According to the local government of Campeche, the Marengo project will be the first green ammonia plant in the country and will be powered through 415MW of onshore wind and 208MW of solar PV

“Marengo will play an important role in the production of renewable ammonia for the European Union,” said Hy2gen CEO Cyril Dufau-Sansot.

“This is mainly due to the ideal conditions at the site location, such as constant wind and many hours of sunshine. Marengo’s electricity needs will therefore be secured by a 415MW wind farm and a 230MW solar farm.”

Renewable ammonia, a nitrogen-and-hydrogen molecule, has enormous promise for decarbonizing numerous industrial and transportation sectors, including shipping

Hy2gen hopes to make a significant contribution to the production of renewable ammonia for the European Union market with the Marengo project.
