Carbon Capture Costs: FEED & pre-FEED Cost Reports

ION Clean Energy, with Nebraska Public Power District, is conducting a FEED study to retrofit a CO₂ capture system on Unit 2 of the 700 MWe Gerald Gentleman Station in Nebraska. Using ION’s low-aqueous ICE-21 solvent, proven in prior DOE-funded projects to reduce energy use, solvent degradation, and emissions, the design will feature two parallel 350 MWe capture units. The project aims to decarbonize most of Unit 2 while maintaining maximum operational flexibility for the plant.

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.
