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.

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.
