Resource Assessment

Overview

The Resource Assessment explores the region’s ability to capture, transport, and store carbon dioxide (CO₂), ensuring the Trail of the Chiefs project is practical and sustainable.

CO2 Sources

The project aims to manage 50 million metric tons of CO₂ annually, sourced from 38 industrial facilities, including power plants, manufacturing sites, and refineries. Partners like Black Hills Energy, the Crow Nation, and Rocky Mountain Power have already committed to contributing substantial amounts of CO₂ for storage.

Geologic Storage Sites

Nine underground storage sites, known as saline reservoirs, have been identified as suitable for safely storing CO₂. These sites are supported by federal initiatives, such as the Department of Energy’s CarbonSAFE program, to ensure secure, long-term storage options.

Pipeline and Transportation Infrastructure

The project plans to build 785 kilometers (approximately 488 miles) of open-access pipelines, connecting key locations in Hannover, Colstrip, and Gillette. Using advanced technology, the pipeline routes are designed to reduce environmental impact, avoid sensitive areas, and utilize existing infrastructure whenever possible.

Regulatory and Environmental Considerations

The feasibility study addresses land use, environmental protection, and potential community impacts. Collaboration with federal, state, and Tribal regulators will ensure that permitting and environmental requirements are met.
