Vol 1 Chapter 3: Economic and Cost Analysis for CO2 Capture Costs in the Capture Project Scenarios

Torgeir Melien

Abstract: A common economic model was developed to facilitate direct and transparent comparison of the technologies studied and selected by the CCP. The CEM team worked closely with the technology development teams to ensure accuracy. The CEM accounted for site-specific scenarios, comparative case analysis, significant non-capture facility costs, multi or byproduct output, technology comparison rather than project evaluation, and generic versus regional pricing. These factors were used along with single discount factors, pre-tax analysis, and emission taxes to ensure a fair comparison. Each scenario was evaluated and compared exhaustively. For some technologies cost reductions above 50% on a CO2-avoided basis are indicated. The European Refinery (UK) Scenario case yielded cost reductions up to 48% for an oxyfuel case. The Alaska (Distributed Gas Turbines) Scenario showed only 19% savings in a pre-combustion decarbonization case. The Norway scenario (new-build large-scale gas turbines) showed cost reductions of 54% for a best integrated technology case and of 60% for a precombustion decarbonization system with hydrogen membrane reformers. The Canada Scenario (IGCC) showed savings of 16% over a highly optimized baseline gasification process.
