A potential CCUS system at PacifiCorp’s Jim Bridger Units 3 and 4, in Wyoming.

In 2017, as part of the Integrated CCS Pre-Feasibility phase of the CarbonSAFE Initiative, the University of Wyoming, in partnership with DOE, will perform a phase I pre-feasibility assessment for secure, commercial-scale CO2 capture and storage at the Rock Springs Uplift, Wyoming.

The project’s initial scenario and related study objectives are to perform a CO2 source assessment based on post-combustion capture of CO2 from PacifiCorp’s Jim Bridger Plant and a CO2 transportation assessment involving the utilization of either the nearby existing CO2 pipeline network or through a new direct pipeline organized by the Wyoming Pipeline Corridor Initiative, and an evaluation to identify additional storage reservoirs within the RSU beyond the Madison and Weber formations to enhance storage capacities with stacked storage.

In March 2022, PacifiCorp filed a CCUS application for compliance. The application included a feasibility analysis of CCUS technologies and the company’s coal-fired generation units in Wyoming. The analysis identified Dave Johnston Unit 4 and Jim Bridger Units 3 and 4 as potentially suitable candidates for CCUS.

In November 2022, PacifiCorp issued two CCUS RFPs, one for Jim Bridger Units 3 and/or 4, and one for Dave Johnston Unit 4. Proposals were due March 7, 2023, and PacifiCorp is evaluating information received.
