Carbon Capture Costs: FEED & pre-FEED Cost Reports

Electric Power Research Institute (EPRI), with Fluor Corporation and California Resources Corporation (CRC), conducted a FEED study to assess the feasibility of retrofitting Fluor’s solvent for post-combustion CO₂ capture at the 550 MW Elk Hills NGCC power plant. The system aims to capture approximately 4,000 tonnes of CO₂ per day (75% of total emissions, or 90% of an 83% slipstream), with the captured CO₂ intended for enhanced oil recovery. Deliverables include the full engineering design package—such as process flow diagrams, equipment datasheets, and capital cost estimates—optimized for site-specific performance, operations, and construction practices.

The Peterhead CCS Project in Aberdeenshire, Scotland, was designed to demonstrate the world’s first commercial-scale post-combustion CO₂ capture from a gas-fired power station. Using amine-based CANSOLV technology, it aimed to capture around one million tonnes of CO₂ annually from one turbine at SSE’s Peterhead Power Station, compress and condition it, and transport it via a new offshore pipeline for injection into the depleted Goldeneye gas reservoir over 2 km beneath the North Sea. The FEED study defined project scope, refined CAPEX and OPEX estimates, and assessed cost uncertainties, providing a basis for the Execute phase while also documenting budget performance and emergent costs during FEED.

Milton R. Young Station Unit 2 is conducting a FEED study to add a post-combustion CO₂ capture system using Fluor’s Econamine FG Plus™ technology to its lignite-fueled power plant in North Dakota. The design targets 3.6 million tonnes of CO₂ captured annually—twice the scale of the largest existing facility—while integrating advanced heat recovery, aerosol and solvent degradation controls, and cold-climate optimization to achieve the lowest levelized cost of capture at world scale. The study will deliver detailed design, cost, and performance data for financing, permitting, and final project scheduling.
