Maire Tecnimont S.p.A. and its subsidiaries NextChem, MET Development and Stamicarbon have reached an agreement with US-based Greenfield Nitrogen LLC, to develop the first dedicated green ammonia plant in the US Midwest.
As part of the agreement, NextChem will start a feasibility study for the 240 metric tons per day green ammonia project, utilizing renewable energy as feedstock via the intermediate production of green hydrogen.
MET Development will assist Greenfield Nitrogen in the development of the project. The plant will be designed utilizing the best available technologies for the green hydrogen production together with the ammonia technology that will be provided by Stamicarbon, which earlier this year launched its new STAMI Green Ammonia technology.
The project is the first of a series of green ammonia facilities that Greenfield Nitrogen is interested to strategically develop in the US Corn Belt. The plant and storage facility, which will be located near Garner, Iowa, will be powered by local renewable sources and will supply the ammonia to the local market, which traditionally is a large ammonia-consuming market.
The green ammonia plant will strengthen the development of the low carbon industry in the region and is expected to save over 166,000 tons of CO2 emissions per annum. The production of around 83,000 tons of ammonia per annum will reduce the region’s dependency on the ammonia currently imported from abroad.
