Carbon Capture Costs: FEED & pre-FEED Cost Reports

Calpine Texas CCUS Holdings LLC, with Electricore Inc., is conducting a FEED study for a modular post-combustion CO₂ capture system at the Deer Park Energy Center NGCC plant in Texas. Using Shell’s commercial-scale amine technology, the system will capture 95% of emissions—about 5 MTPA—while maintaining low energy use and fast reaction rates. The study will include business case, techno-economic, life cycle, environmental, and public policy analyses, including environmental justice and job creation impacts.

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.

Linde Inc., with Linde Engineering Americas, Linde Engineering Dresden, and Svante Inc., is completing an initial engineering design for a commercial-scale CO₂ capture plant at its steam methane reforming hydrogen facility in Port Arthur, Texas. Using Svante’s VeloxoTherm™ solid adsorbent technology, the system will capture about 1 million tonnes of CO₂ annually at ≥90% efficiency while producing 99.97% pure “blue” hydrogen. The design will include ISBL units for flue gas conditioning and CO₂ purification, OSBL components, and a techno-economic analysis of capture costs and hydrogen production economics.
