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.

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.

General Electric Gas Power, with Linde, Kiewit, and Southern Company Services, is conducting a FEED study for a “Generation 2” amine-based post-combustion CO₂ capture system at an existing NGCC power plant. Targeting at least 95% capture efficiency, the design will emphasize optimized integration, lower CCS costs, and flexible operation to complement renewable energy. The 18-month project will progress from multiple conceptual designs to a single configuration, culminating in a detailed design, technical viability assessment, techno-economic and life cycle analyses, and a business case evaluation.
