CO2 Sources, Storage, and Transport
The Trail of the Chiefs project focuses on building a robust carbon management network to capture, transport, and store CO₂ across Montana, North Dakota, and Wyoming. By utilizing advanced planning tools, the project identifies optimal routes and infrastructure to connect industrial CO₂ sources with storage and conversion sites. This network is designed to handle significant carbon volumes annually, helping to reduce regional emissions and support sustainable energy practices.
The proposed transport system spans over 1,300 miles and connects key hubs in the region, ensuring efficient CO₂ movement while minimizing environmental impacts. By leveraging existing infrastructure where possible, the project aims to reduce costs and preserve sensitive areas. Managed by experienced industry leaders, this network will serve as a cornerstone for advancing carbon management and promoting cleaner energy solutions.
CO2 Composition and Transport
The Trail of the Chiefs project evaluated 38 industrial CO₂ sources, including power plants and manufacturing facilities, identifying significant volumes of CO₂ suitable for capture and storage. Each facility was assessed to ensure it met the required thresholds for efficient carbon capture and transport.
Pipeline transport was chosen as the most effective method for moving CO₂ due to its reliability and scalability. The CO₂ transported will meet high purity and safety standards, ensuring compatibility with storage and conversion facilities. This approach supports the project’s goal of creating a robust and efficient carbon management network for the region.
Pre-FEED Study
The pre-FEED study focused on planning and analyzing three main pipeline routes: Hannover to Ekalaka, Ekalaka to Colstrip, and Ekalaka to Gillette. Engineering assessments were conducted to determine the best pipeline design and operational setup, ensuring smooth and efficient CO₂ transportation.
The pipeline system will include five pumping stations equipped with advanced technology for flow management, leak detection, and future expansion capabilities. The project is carefully mapped out over four years, with key steps for design, permitting, and construction leading up to the system’s expected operation in 2029.
Preliminary Business Case Analysis
The business case analysis examined the financial feasibility of the Trail of the Chiefs pipeline network, focusing on long-term economic sustainability and operational efficiency. The analysis highlights how the project will initially benefit from federal incentives, such as tax credits, to support its early operations and ensure financial viability.
As the project progresses, it will transition to generating revenue through the growing carbon market, maintaining its economic stability over time. The open-access design of the pipeline network is a key feature, allowing for future integration of additional CO₂ sources, ensuring flexibility, scalability, and the ability to adapt to evolving carbon management needs.
Regulatory Plan Analysis
The regulatory plan ensures that the Trail of the Chiefs project complies with all federal, state, and local permitting requirements. At the federal level, the project aligns with safety and environmental standards under regulations such as the National Environmental Policy Act (NEPA), the Clean Water Act, and the Clean Air Act. State-specific approvals will be obtained from agencies in Montana, North Dakota, and Wyoming, including necessary land easements.
A strong focus is placed on community outreach and stakeholder engagement throughout the planning process. Letters of support have been secured from tribal nations, labor unions, and other key stakeholders. The plan highlights the importance of voluntary land agreements and ongoing dialogue with local communities to ensure their concerns are addressed and that the project reflects shared values and priorities.
