Carbon Capture Costs: FEED & pre-FEED Cost Reports

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.

Electricore Inc., with Svante Inc. and Kiewit Engineering Group Inc., is conducting a pre-FEED study for a 1 million tonnes/year VeloxoTherm™ carbon capture system at LafargeHolcim’s cement plant in Florence, Colorado. The system will capture CO₂ from both kiln flue gas (14% concentration) and a natural gas-fired steam generator (8.5% concentration), with storage options including saline formations, depleted oil reservoirs, and the Sheep Mountain CO₂ reservoir. The study will also evaluate expansion to 2 million tonnes/year and target DOE’s $30/tonne capture cost goal, progressing from design selection (FEL-1) to pre-FEED engineering (FEL-2).

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.
