Vaults

CRC has applied for several Class VI permits to the U.S. Environmental Protection Agency (EPA) for underground storage vaults across California, in the San Joaquin and Sacramento basins. Once permitted, these vaults will have the ability to permanently store carbon dioxide (CO2) from industrial sources in deep, depleted underground reservoirs.

CTV I

CRC has applied for permits and the environmental review has begun for two initial permanent carbon capture and storage (CCS) vaults, collectively referred to as Carbon TerraVault I (CTV I), located within the proposed CTV Clean Energy Park (previously Net Zero Industrial Park) at Elk Hills in Kern County, California. This park is a growing assemblage of emerging green projects that have — and will continue to — come to Kern County as a Carbon Management Center of Excellence in California. Industries are attracted not only by Elk Hills’ reservoirs, but also by a well-understood permitting path that adheres to California’s stringent environmental regulations. These are ideal conditions for CCS projects with companies that are leading the energy transition in California and beyond.

With a total estimated capacity of up to 46 million metric tons (MT) of storage, CTV I is expected to be capable of injecting over 1 million MT of CO2 per year, equivalent to the annual emissions of approximately 200,000 passenger vehicles.

In December 2022, Carbon TerraVault JV Holdco, LLC (CTV JV) entered into a Carbon Dioxide Management Agreement (CDMA) with Lone Cypress Energy Services, LLC. Called the Elk Hills Hydrogen Project, the project will sequester 205,000 MT of CO2 per annum in the CTV I carbon storage vault from a newly constructed clean hydrogen plant at the proposed CTV Clean Energy Park at Elk Hills.

In May 2023, CTV entered into a CDMA with InEnTec, Inc., to build a new renewable dimethyl ether (rDME) production facility at the CTV Clean Energy Park at Elk Hills. CTV will sequester initially a minimum 100,000 MT of CO2 per annum from the InEnTec Facility in the CTV I carbon storage vault.

In July 2023, CTV JV entered into a CDMA with Verde Clean Fuels to sequester a minimum of 100,000 metric tons of CO2 per annum at the CTV I vault from a new renewable gasoline plant to be constructed at the CTV Clean Energy Park at Elk Hills.

In November 2023, CTV JV entered into a CDMA with with NLC Energy (NLCE) to build a new waste-to-energy production facility to produce renewable natural gas (RNG) from biomass and other agricultural waste feedstock. CTV will sequester a minimum of 150,000 MT of CO2 per annum from the NLCE Facility in the CTV I carbon storage vault.

CRC also announced plans to construct a capture-to-storage facility at the proposed CTV Clean Energy Park at Elk Hills that will remove approximately 100,000 MT per annum of associated CO2 from inlet gas used for the Elk Hills Power Plant for permanent sequestration at the CTV I reservoir.

CCS projects that will be located at the proposed CTV Clean Energy Park at Elk Hills will not require off-site transportation as the projects will be located close to the sequestration injection points.

CCS projects can have immediate and long-lasting environmental, economic, and employment benefits to nearby communities. The Elk Hills Field is of particular focus given the ample availability of multiple depleted reservoirs. The rural Elk Hills oil complex spans nearly 75 square miles, with no burden on local communities, and includes more than 25,000 acres of habitat conservation lands.

CTV II & III

In May 2022, CRC applied for two Class VI permits for 94 million metric tons of permanent CO2 storage for two new CCS vaults - CTV II and Ill - in the Sacramento basin.

In January 2023, CRC announced a CDMA with independent clean-tech company Grannus, LLC. The Grannus Ammonia and Hydrogen Project will sequester 370,000 MT of CO2 per annum at CTV III from a new clean ammonia and hydrogen plant to be constructed in Northern California to supply the agriculture, mobility and marine fuel markets.

Applied for two class vi permits for an additional 94 million metric tons of estimated storage

CTV IV

In May 2023, CRC applied for a Class VI permit for 34 million MT of permanent CO2 storage for the CTV IV CO2 reservoir in the Sacramento Basin.

CTV V

In August 2023, CRC applied for a Class VI permit for 17 million MT for the CTV V CO2 reservoir in the Sacramento Basin.

Full Scope Net Zero

As we transition toward a net zero future, we believe low carbon and net zero solutions such as our Carbon TerraVault CCS projects can create additional energy transition jobs in our state while also providing Californians with fuel that has a substantially lower carbon intensity than that of an imported barrel, further lowering our overall carbon emissions as well as the state’s carbon emissions.

Together We Power California

CRC's workforce is dedicated to California and our local communities, and safely advancing solutions for reducing emissions that are aligned with the state’s emissions reduction goals.

I’m honored to be able to help provide innovative decarbonization technology solutions like Carbol TerraVault that’s going to revolutionize how we combat climate change here in California.
