Maire Tecnimont Group (MT.MI) has signed an agreement with Greenfield Nitrogen LLC for the development of a green ammonia plant in the U.S.

Maire Tecnimont's subsidiaries MET Development, Stamicarbon and NextChem have entered into an agreement with Greenfield Nitrogen LLC to develop the first dedicated green ammonia plant in the midwest. As part of the deal, NextChem will launch a feasibility study for the 240 metric tpd green ammonia project using green energy through the intermediate production of green hydrogen. MET Development will assist Greenfield Nitrogen in the development of the project. The technology for the plant will be supplied by Stamicarbon, which earlier this year launched its new STAMI Green Ammonia technology.

The project is the first in a series of green ammonia plants that Greenfield Nitrogen wishes to strategically develop in the Corn Belt of the United States. The plant and storage facility, which will be located near Garner, Iowa, will be powered by local renewable sources and supply ammonia to the local market, which has traditionally been a large ammonia consuming market.

The green ammonia plant will enhance the development of low carbon industry in the region and is expected to save more than 166,000 t of CO₂ emissions per year. The production of around 83,000 t of ammonia per year will reduce the region's dependence on ammonia currently imported from abroad.
