The Tallgrass CO2 Pipeline Project: Weighing the Prospects and Pitfalls

The Tallgrass CO2 pipeline project, a collaborative venture between Tallgrass Energy and Archer Daniels Midland Company (ADM), is a significant stride in carbon capture and sequestration (CCS).

This initiative aims to reduce atmospheric CO2 by capturing emissions from ADM's corn-processing complex in Nebraska and transporting them to a sequestration site in Wyoming. While the project promises environmental and economic benefits, it also faces a spectrum of potential risks and raises questions about the fate of land acquired through eminent domain. This blog post offers a detailed examination of the project's benefits, challenges, and implications for land ownership.

The Promise of Carbon Capture

The project's vision is to harness CCS technology to capture over 10 million tons of CO2 annually from industrial sources. By repurposing the existing Trailblazer natural gas pipeline for CO2 transport, Tallgrass Energy is minimizing the need for new construction and reducing the project's environmental footprint.

Benefits of Success

Environmental Impact

  • Climate Change Mitigation: The project could significantly contribute to global decarbonization efforts, helping to combat climate change.
  • Ethanol Industry Sustainability: It supports Nebraska's ethanol industry, which is integral to the state's economy and agricultural sector, by providing a means to reduce carbon emissions.

Economic Advantages

  • Job Creation: The construction and operation of the pipeline are expected to create jobs and stimulate the local economy.
  • Energy Infrastructure Innovation: The project could serve as a model for future CCS initiatives, showcasing the potential for repurposing existing energy infrastructure.

Challenges and Liabilities

Environmental and Safety Risks

  • CO2 Leakage: There is a risk of CO2 leakage from the pipeline or sequestration site, which could negatively affect the environment.
  • Health Hazards: Pipeline ruptures or leaks could pose significant health risks to nearby communities due to CO2's asphyxiant properties.

Financial and Operational Concerns

  • Project Costs: Technical challenges, regulatory hurdles, or public opposition could lead to cost overruns and delays.
  • Policy Dependence: The project's financial model may rely on government incentives like the 45Q tax credit, making it vulnerable to policy changes.

Regulatory and Legal Issues

  • Permitting Complexities: The process of obtaining necessary permits can be fraught with uncertainties and delays.
  • Eminent Domain: Using eminent domain to acquire land for the pipeline has sparked concerns about landowner rights and compensation.

Land Ownership and Eminent Domain

A critical aspect of the Tallgrass CO2 pipeline project is acquiring land through eminent domain. This legal process allows for the compulsory purchase of private land for public use, provided that just compensation is given. In the case of the Tallgrass pipeline, land obtained through eminent domain is intended for the construction and maintenance of the pipeline infrastructure.

The Fate of the Land

  • During the Project: While the pipeline is in operation, the land will typically remain under the ownership of Tallgrass Energy, as the company is responsible for the maintenance and safety of the pipeline.
  • If the Project is Abandoned: Should the pipeline project be discontinued or decommissioned, the ownership and future use of the land could become a complex issue. Depending on the terms of the eminent domain agreement and state laws, the land may be sold, repurposed for other public uses, or potentially returned to the original landowners under certain conditions.

The Stakes of Success and Failure

The success of the Tallgrass CO2 pipeline project would bring environmental and economic benefits, while failure could lead to financial losses and environmental setbacks. The stakes are particularly high for local communities and landowners affected by the project.

If the Project Succeeds

  • Beneficiaries: The project's success would benefit the environment, local economy, ethanol and agriculture industries, and companies involved.

If the Project Fails

  • Affected Parties: Financial losses would impact Tallgrass Energy, ADM, and their investors. Landowners and communities could face significant hardships if the land acquired through eminent domain is not restored or compensated adequately.


The Tallgrass CO2 pipeline project is a bold initiative with the potential to impact the environment and the economy positively. However, it also presents challenges that must be carefully managed, particularly regarding land acquisition and the use of eminent domain. The project's success hinges on balancing these benefits and risks, ensuring environmental protection, and addressing the concerns of all stakeholders involved. As the project unfolds, its legacy will be defined by its ability to navigate these complexities and deliver on its promise of a sustainable future.
