Greenfield Nitrogen Partners Up to Build Green Hydrogen and Ammonia Facility

NextChem, a subsidiary of Maire Tecnimont, is focused on the field of green chemistry and technologies for the Energy Transition. Recently, NextChem, along with Maire Tecnimont’s other subsidiaries MET Development and Stamicarbon, have reached an agreement with Greenfield Nitrogen, LLC to develop the first dedicated green ammonia plant in the US Midwest, specifically in Iowa.

Greenfield Nitrogen is working on developing a crucial network of green hydrogen and ammonia facilities along the Midwest to serve the emerging renewable energy markets. With the new advancements in electrolysis technology, their plant design is a completely green, carbon free hydrogen and ammonia facility which will use 100% renewable energy as well as significantly less water than conventional hydrogen and ammonia production. 

To kickstart this agreement, NextChem will start a feasibility study for the 240 tpd green ammonia project, using renewable energy as feedstock through the intermediate production of green hydrogen. MET Development will assist Greenfield Nitrogen in the development throughout the project. Stamicarbon will provide the ammonia technology used in the plant.

This green ammonia plant will strengthen the development of the low carbon industry in the region. The companies estimate it will save over 166,000 tpy of CO2 emissions. Since it will also produce approximately 83,000 tpy of ammonia, it will reduce the dependency on importing ammonia from abroad and further reduce the carbon footprint for the industry.

Linda Thrasher, President, Greenfield Nitrogen, LLC commented: “This partnership represents a collaboration of strengths. As a development partner, Maire Tecnimont and its subsidiaries bring decades of expertise in successfully designing and executing nitrogen projects as well as creating new technology, including state-of-the-art zero-carbon facilities. Greenfield’s development expertise, operational experience, and market knowledge align well and position both companies to play a critical role in meeting the world’s decarbonization goals.”
