The Hawaii Senate has introduced a significant legislative bill, SB1339, aimed at establishing a comprehensive carbon sequestration and underground water resource characterization program. Introduced on February 11, 2025, the bill seeks to enhance the state's environmental management and energy security by identifying and assessing underground water and carbon sequestration resources through a method known as slim-hole boring exploration.

The proposed program will be implemented by the Hawaii State Energy Office, which is tasked with conducting a statewide environmental assessment in collaboration with the Hawaii Groundwater and Geothermal Resources Center at the University of Hawaii or similar institutions. This initiative is designed to engage local communities, ensuring that their needs and concerns are addressed during the assessment process.

Key provisions of the bill include a requirement for the Hawaii State Energy Office to report its findings and recommendations to the legislature by 2028, making the information publicly accessible through commonly used mapping software. The bill also allocates substantial funding, with $16.5 million appropriated from the energy security special fund for the fiscal years 2025-2026 and 2026-2027, alongside an additional $135,000 from general revenues to establish a permanent position to support the program.

While the bill has garnered support for its potential to bolster Hawaii's environmental initiatives and energy strategies, it may face scrutiny regarding its long-term implications and the effectiveness of the proposed methods. Experts suggest that the success of the program will depend on the active involvement of local communities and the transparency of the assessment process.

As Hawaii continues to navigate the challenges of climate change and resource management, SB1339 represents a proactive step towards sustainable development. The bill is set to take effect on May 13, 2040, marking a significant milestone in the state's efforts to enhance its environmental resilience and energy independence.
