In a recent Kern County Board of Supervisors meeting, officials discussed the first carbon capture and storage (CCS) project in California aimed at permanently storing carbon dioxide (CO2) underground. The project, proposed by California Resources Corporation, spans over 9,000 acres in the Elk Hills Oil Field and is currently undergoing an environmental impact report.
The CCS process involves capturing CO2 emissions from a source, compressing it, and injecting it over a mile underground into designated pore spaces for permanent storage. This project is distinct from typical conditional use permits as it does not involve new surface structures or activities, although it will still adhere to specific conditions.
The project will utilize class 6 injection wells and a pipeline system to transport the captured CO2. The regulatory framework for the project includes local land use approvals, state evaluations under SB 905, and federal oversight from the U.S. Environmental Protection Agency (EPA). Notably, the project cannot be implemented without local approval, emphasizing the importance of Kern County's role in the regulatory process.
Safety concerns regarding CO2, which can displace oxygen and pose health risks at high concentrations, were highlighted. The project includes comprehensive safety measures, such as automatic shutdown valves and continuous monitoring systems to detect leaks.
The CCS project is expected to have a total storage capacity of approximately 49 million metric tons of CO2, with injection anticipated to reach capacity within 25 years, followed by 75 years of monitoring. The project aims to contribute to California's climate goals while ensuring the safety and environmental integrity of the surrounding areas.
