Toward Improved Guidelines for Uncertainty Analysis of Carbon Capture and Storage Techno-economic Studies

SSRN Electronic Journal (2021)

Mijndert van der Spek George Booras Timothy Fout Mónica García Michael Matuszewski

Uncertainty analysis is a key element of sound techno-economic analysis (TEA) of CO2 capture and storage (CCS) technologies and systems, and in the communication of TEA results. Many CCS technologies are novel concepts, that are still in the early (pre-commercial) stages of development. Therefore, uncertainties in their technology performance and cost are often substantial, making it imperative that they be characterized, and their impacts reported. Although uncertainty analysis itself is not novel, with some methods already frequently used by the CCS TEA community, a document that provides a comprehensive overview of methods and approaches, as well as guidance on their selection and use, is still lacking. Given its importance, we seek to fill this gap by providing a critical review of uncertainty analysis methods along with guidance on the selection and use of these methods for CCS TEAs, highlighting good practice and examples from the CCS literature. There are many opportunities to bring the use of uncertainty analysis to a higher level than currently practiced. This review of and guidance on available methods is intended to help accelerate continued methods development and their application to more robust and meaningful CCS performance and cost studies.

Cost and Performance Baseline for Fossil Energy Plants Volume 1b: Bituminous Coal (IGCC) to Electricity Revision 2b – Year Dollar Update

Timothy Fout Alexander Zoelle D.L. Keairns Marc Turner Mark Woods

This report presents the cost and performance results of an assessment of seven integrated gasification combined cycle (IGCC) plants. The primary value of this report lies not in the absolute accuracy of the capital cost estimates for the individual cases (estimated to be -15 percent/ 30), but in the application of a consistent approach to allow meaningful comparisons of relative costs among the cases evaluated. This report, Volume 1b, retains the IGCC design and performance updates from the November 2010 release of Volume 1 (Revision 2)1, but updates the IGCC costs for all cases to 2011 year dollars. Volume 1a covers the cost and performance update of all pulverized coal (PC) and natural gas combined cycle (NGCC) cases. Section 4 has a revision control table listing the updates applied to this report.

Techno-Economic Analysis of Sorbent-Based Direct Air Capture Informed by EPC Input and Recent Technological Advancements

SSRN Electronic Journal (2025)

Kshitij Patel Troy Teel Samuel Henry Hari Mantripragada Alexander Zoelle

Direct air capture (DAC) technology has been developing at an accelerated rate. Independent, comprehensive, and transparent techno-economic analyses (TEAs) of DAC technologies are required to inform future development. NETL is publishing an update to the 2022 sorbent-based DAC case study report. This manuscript highlights select TEA results that will be presented in the upcoming NETL report. The analysis considers three sorbent-based DAC system configurations (direct steam temperature swing, indirect steam temperature swing, and direct steam temperature/vacuum swing) and two scenarios for providing the required electricity and steam (stand-alone system with a combined heat and power plant generating the required steam and electricity, and a purchased power case utilizing an electric boiler). Detailed sensitivity analyses are included and highlight the impact of external market factors, sorbent performance, and economies of scale. The potential for cost reductions by opting for temperature vacuum swing adsorption is highlighted. More detailed background and TEA results will be presented in the upcoming NETL report titled "Direct Air Capture Case Studies: Sorbent System (Revision 1)".
