Carbon Capture Costs: FEED & pre-FEED Cost Reports

Southern Company Services, with Linde Gas North America, is conducting a FEED study for a commercial-scale CO₂ capture system using Linde-BASF’s advanced aqueous amine technology at an NGCC plant of at least 375 MWe. The project will evaluate Alabama Power’s Plant Barry and Mississippi Power’s Plant Daniel to select the optimal host site, define project requirements, optimize process design, and deliver engineering packages along with a cost and schedule estimate within 15% accuracy. The study will build on prior feasibility work and site-specific testing.

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.
