Denbury, Nutrien in Louisiana CCS collaboration

Denbury Carbon Solutions and US fertiliser producer Nutrien said May 18 they had reached a term-sheet agreement under which Denbury will transport and store CO₂ captured from potential clean ammonia production at Nutrien’s Geismar facility in Louisiana.

Nutrien has been capturing CO₂ from nitrogen production at Geismar since 2013, and has so far sequestered more than 3mn mt of CO₂. It’s now evaluating carbon capture and storage (CCS) in the ammonia production process that would produce 1.2mn mt/yr of clean ammonia and capture 1.8mn mt/yr of CO₂.

Front-end engineering and design work is underway, and a final investment decision is expected in 2023. Full production and CO₂ capture would begin in 2027.

The Nutrien partnership is developing alongside Denbury’s US CO₂ transportation and storage business, which is now moving and storing about 14mn mt/yr of CO₂. It is also pursuing additional CCS opportunities in Louisiana, Texas and Alabama with the potential to store as much as 1.4bn mt.
