Carbon Capture Costs: FEED & pre-FEED Cost Reports

The Red Trail Energy (RTE) ethanol facility in Richardton, North Dakota, is implementing a CO₂ capture and liquefaction system designed by Trimeric. The system captures CO₂ from fermentation, compresses it to ~350 psig, dehydrates and liquefies it using an ammonia refrigeration loop, and purifies it via distillation to remove oxygen and other gases. The liquid CO₂ can be stored for sale or geologic sequestration. The facility is designed to process 587 tonnes/day (scalable to 675 tonnes/day), with nearly complete CO₂ recovery.

Linde Inc., with Linde Engineering Americas and BASF, is conducting an initial engineering design for a 3,500 tonnes/day CO₂ capture plant using Linde-BASF’s advanced aqueous amine technology at a Linde-owned steam methane reforming facility. The project will define integration options, establish project requirements, optimize process design, and develop engineering, cost, and schedule packages. BASF will provide the technology design, LEA will deliver detailed engineering and constructability assessments, and Linde will lead techno-economic, environmental, and safety analyses in coordination with the SMR plant operators.

The University of Illinois at Urbana-Champaign is leading a FEED study for a commercial-scale CO₂ capture system at Holcim’s Ste. Genevieve cement plant in Missouri, targeting 95% capture efficiency. Using Air Liquide’s Cryocap™ technology, which combines PSA pre-concentration with cryogenic purification, the system will produce high-purity CO₂ for storage near the Prairie State Generating Company in Illinois. UIUC will manage the project and perform economic and impact analyses, while Air Liquide, Kiewit, Visage Energy, and Holcim will contribute to design, safety, environmental, and site integration efforts.
