Carbon Capture Costs: FEED & pre-FEED Cost Reports

Bechtel National Inc., with the Electric Power Research Institute, is conducting a FEED study to retrofit Panda Power Funds’ 758 MWe natural gas combined cycle plant in Sherman, Texas, with a post-combustion CO₂ capture system. Using an open-access design and a conventional amine absorber-stripper system with a non-proprietary solvent such as MEA, the project targets CO₂ capture for enhanced oil recovery.

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.

Southern Company Services, with Linde Gas North America, is conducting a FEED study for a commercial-scale CO₂ capture system using Linde-BASF’s advanced aqueous amine technology at an NGCC plant of at least 375 MWe. The project will evaluate Alabama Power’s Plant Barry and Mississippi Power’s Plant Daniel to select the optimal host site, define project requirements, optimize process design, and deliver engineering packages along with a cost and schedule estimate within 15% accuracy. The study will build on prior feasibility work and site-specific testing.
