Carbon Capture Costs: FEED & pre-FEED Cost Reports

In March 2010, the Scottish CCS (Carbon Capture & Storage) Consortium began an extensive Front End, Engineering and Design (FEED) study to assess what exactly would be required from an engineering, commercial and regulatory, perspective in order to progress the CCS demonstration project at Longannet Power station in Scotland (Goldeneye) through to construction. The study has yielded invaluable knowledge in areas such as cost, design, end-to-end CCS chain operation, health and safety, environment, consent and permitting, risk management, and lessons learnt.

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.

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.
