Maire Tecnimont Awarded Green Hydrogen & Ammonia Plant Design Contract

12.02.2024 - Maire Tecnimont has been awarded a FEED contract by MadoquaPower2X to develop an integrated green hydrogen and green ammonia plant located in the industrial zone of Sines, Portugal. MadoquaPower2x is a consortium comprised of Madoqua Renewables, Power2X, and Copenhagen Infrastructure Partners (CIP), through its Energy Transition Fund.

The project involves the production of green hydrogen using alkaline-water electrolyzer technology and production of green ammonia through the Haber-Bosch process. Green ammonia will be transported by pipeline to the Port of Sines and loaded for export and/or used as maritime fuel.

Tecnimont’s scope of work entails the design of the electrolyzers’ integration, air separation unit for nitrogen production, ammonia production plant, as well as storage and ship loading facilities. The Final Notice to Proceed is expected by 22 March 2024.

This award follows a PRE-FEED carried out by NextChem Tech, Maire’s Sustainable Technology Solutions subsidiary. Tecnimont will provide its EPC (engineering, procurement, and construction) expertise leveraging on NextChem Tech’s technological competences for hydrogen production and storage.

Alessandro Bernini, Maire CEO, commented, “The synergic approach among our Group’s companies is the key success factor of Maire’s value proposition. This award shows the Group’s strength in the green hydrogen and ammonia production segment, which helps supporting the transition to a clean energy system”.

MadoquaPower2X will use renewable energy generated by solar and wind assets under development in Portugal and up to 500 MWs of electrolysis capacity to produce up to 1,200 MTPD of green ammonia. It will be the first facility in Sines, the largest industrial and logistic hub in the Iberian Peninsula, to produce clean energy at an industrial scale and with the highest environmental and safety standards. The project is geared towards the set-up of an export energy carrier value chain between the Port of Sines (Portugal) and Northwestern European Hub.
