Carbon Capture Costs: FEED & pre-FEED Cost Reports

Dastur International Inc., with Cleveland-Cliffs Inc., is designing a carbon capture system for the 5 mtpa integrated steel plant in Burns Harbor, Indiana, to capture 50–70% of CO₂ emissions from blast furnace gas. The system will combine a gas flow distribution network, a specialized conditioning process, and ION Clean Energy’s solvent-based capture technology with 90–98% efficiency, with water-gas shift reactors enabling higher capture rates. Dastur will lead overall plant integration and engineering, while ION designs the capture island and Dastur Energy optimizes design and energy performance.

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.
