Carbon Capture Costs: FEED & pre-FEED Cost Reports

A Front End Engineering and Design (FEED) study was undertaken to design an advanced CO2 Capture Unit (CCU) to produce 1000 tonnes per day of CO2 from the exhaust of three Once-Through Steam Generators (OTSG’s) at Devon Energy’s Jackfish 1 thermal in-situ operations and estimate the capital expenditure for the facilities within +/-15% accuracy. The process utilizes HTC Purenergy Carbon Capture Technology to capture CO2 from the OTSG exhaust gas using an aqueous chemical solvent in an absorber tower, after which the CO2-loaded solvent is passed to a stripper tower where the CO2 is released and the solvent regenerated. The study excludes downstream CO2 compression, dehydration, transportation and storage.

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.

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.
