With an aim to achieve a 90 % reduction in CO2 emissions, Nutrien is assessing its existing Geismar, Louisiana site in the USA to develop the mega clean ammonia production facility. If approved, the 2-billion-dollar facility is expected to offer an annual production capacity of 1.2 million metric tons of clean ammonia.

Saskatchewan/Canada – Nutrien has recently announced that it is evaluating Geismar, LA as the site to build the world’s largest clean ammonia facility. Building on the company’s expertise in low-carbon ammonia production, clean ammonia will be manufactured using innovative technology to achieve at least a 90 percent reduction in CO2 emissions. The project will proceed to the front-end engineering design (Feed) phase, with a final investment decision expected to follow in 2023. If approved, construction of the approximately 2-billion-dollar facility would begin in 2024 with full production expected by 2027.
The new clean ammonia plant would leverage low-cost natural gas, tidewater access to world markets, and high-quality carbon capture and sequestration infrastructure at its existing Geismar, LA facility to serve growing demand in agriculture, industrial and emerging energy markets. The plant is expected to have an annual production capacity of 1.2 million metric tons of clean ammonia and capture at least 90 percent of CO2 emissions, permanently sequestering more than 1.8 million metric tons of CO2 in dedicated geological storage per annum. The new plant will use auto thermal reforming technology to achieve the lowest carbon footprint of any plant at this scale and has the potential to transition to net-zero emissions with future modifications.
“Our commitment to the development and use of both low-carbon and clean ammonia is prominent in our strategy to provide solutions that will help meet the world’s decarbonization goals, while sustainably addressing global food insecurity. Leadership in clean ammonia production will play a key role in achieving our 2030 Scope 1 and 2 emissions reduction goals, as part of our Feeding the Future Plan,” said Ken Seitz, Nutrien’s Interim President and CEO.
Nutrien has signed a term sheet with Denbury, a trusted partner for nearly a decade, that would allow for expansion of the existing volume of carbon sequestration capability in the immediate vicinity of its Geismar facility, if selected as the final site of construction.
Nutrien has also signed a Letter of Intent to collaborate with Mitsubishi Corporation for offtake of up to 40 percent of expected production from the plant to deliver to the Asian fuel market, including Japan, once construction is complete.
