Colorado's House Bill 1165, introduced on April 11, 2025, aims to enhance the state's efforts in combating climate change by regulating geothermal operations and carbon capture technologies. The bill seeks to establish a framework for the oversight of ground heat exchanger contractors, aligning their regulation with existing standards for water well construction and pump installation contractors.

The primary purpose of House Bill 1165 is to support Colorado's ambitious greenhouse gas emission reduction targets, which include a 26% reduction by 2025 and a goal of net-zero emissions by 2050. The legislation recognizes the critical role of carbon capture and storage (CCS) in achieving these targets, particularly for sectors that are challenging to decarbonize. By facilitating the geologic sequestration of carbon dioxide, the bill aims to ensure that CO2 can be safely stored underground, contributing to the state's long-term climate goals.

Key provisions of the bill include the renaming of the state board of examiners of water well construction and pump installation contractors to the "state board of examiners of water well and ground heat exchanger contractors." This change reflects the expanded scope of oversight necessary for the growing geothermal sector. The bill also mandates that ground heat exchanger contractors adhere to the same regulatory standards as their water well counterparts, ensuring a consistent approach to environmental safety and operational integrity.

Debate surrounding House Bill 1165 has centered on the balance between promoting renewable energy technologies and ensuring environmental protection. Proponents argue that the bill is essential for meeting climate goals and fostering innovation in the geothermal sector. However, some opponents express concerns about the potential risks associated with underground CO2 storage and the long-term monitoring required to ensure safety.

The implications of this legislation are significant. By establishing a regulatory framework for geothermal operations, Colorado positions itself as a leader in renewable energy and climate action. Experts suggest that successful implementation of House Bill 1165 could not only help the state meet its emission targets but also stimulate economic growth through the development of new technologies and job creation in the green energy sector.

As the bill moves through the legislative process, stakeholders will be closely monitoring its progress and potential amendments. The outcome of House Bill 1165 could set a precedent for how states approach the regulation of emerging energy technologies in the fight against climate change.
