CTV I – 26R
Carbon TerraVault I (CTV I) is a carbon capture and storage (CCS) site, or vault, composed of two depleted oil and natural gas reservoirs – “26R” and “A1-A2.” Together, these reservoirs make up CTV I, which is located within the Elk Hills Oil Field in Kern County, California.
The 26R reservoir has an expected injection rate of 1.46 million metric tons of carbon dioxide (CO2) storage per annum. Total estimated capacity of 26R is up to 38 million metric tons.
In December 2024, Carbon TerraVault received Class VI permits from the U.S. Environmental Protection Agency (EPA) for underground injection and storage of CO2 into the 26R reservoir. In January 2025, CRC, together with Carbon TerraVault JV, a joint venture between CRC and Brookfield Asset Management, announced California’s first CCS project, a major milestone for CRC, Carbon TerraVault JV, and the energy industry as a whole – having received the nation’s first Class VI permits for use of depleted oil and natural gas reservoirs to sequester CO2. In 2025, CRC broke ground on California’s first CCS project, and first injection began May 2026.
More information about storage and injection will be posted here as available.
