A bill for an act relating to the exercise of eminent domain for carbon oxide pipelines, and including applicability and effective date provisions.(See HF 2104.)

House Study Bill 507 (HSB507) was introduced in the Iowa General Assembly to address the use of eminent domain—the government's power to take private property for public use—for constructing carbon oxide pipelines. The bill aimed to establish specific conditions and limitations under which eminent domain could be exercised for these pipelines. Key provisions likely included requirements for demonstrating public necessity, ensuring fair compensation to landowners, and possibly involving public hearings or environmental assessments. The bill was renumbered as House File 2104 (HF 2104) on January 15, 2026, and progressed through the legislative process, including committee approvals and amendments.

Supporters of HSB507 and its successor, HF 2104, argued that the legislation provided necessary safeguards for landowners, ensuring that eminent domain for carbon oxide pipelines would be exercised responsibly and fairly. They emphasized that the bill balanced the state's energy infrastructure needs with property rights, promoting transparency and public involvement in the process.

Opponents contended that the bill could hinder the development of carbon capture and storage projects by imposing stringent requirements on the use of eminent domain. They expressed concerns that such regulations might deter investment in clean energy infrastructure and impede efforts to reduce carbon emissions. Additionally, some critics believed that the bill did not go far enough in protecting landowners' rights and called for more comprehensive reforms.
