One Gigawatt, 6,000 Megawatts and Idle Oil Wells: California's Second Life for Oil Infrastructure

California Resources Corporation signed a memorandum of understanding with Bloom Energy on November 2 to evaluate at least one gigawatt of solid-oxide fuel-cell generation paired with carbon capture and storage. The MOU lands on a grid that, by order of the California Public Utilities Commission, must add 6,000 megawatts of new clean energy and storage net qualifying capacity for the 2029–2032 period — with at least a quarter carrying clean, firm generation or long-duration storage attributes.

The pairing matters because the CPUC directive measures dependable contribution to grid reliability, not nameplate ratings. That distinction, argued Geo2Watts Co-Founder and CEO Philip Cruver in the opinion piece at the center of this story, creates a reason to evaluate technologies that can deliver power through critical periods rather than simply stack megawatt-hours.

What does the gigawatt commitment actually cover?

The CRC–Bloom evaluation spans potential front-of-the-meter and behind-the-meter applications of fuel-cell generation with carbon capture. It is not yet a commitment to build. It does signal CRC moving beyond its traditional petroleum business toward an integrated portfolio of power and carbon-management services, drawing on subsurface knowledge, land and industrial infrastructure in Kern County for permanent CO₂ storage.

Geo2Watts, the company Cruver leads, sees an analogous opening in long-duration storage: a new revenue-producing role for well assets, operating expertise and electrical infrastructure that might otherwise hold limited remaining economic value.

Two regions, two technologies

Kern County and Long Beach anchor the strategy. Kern County hosts CRC's carbon-management work on permanent storage of captured CO₂. Long Beach hosts the THUMS islands, with mature oilfield infrastructure, established electrical loads and extensive operating knowledge — the proving ground Geo2Watts is exploring for pilot applications.

The company's proposed Borehole Battery™ uses electricity to run an aboveground high-temperature heat pump, storing heat in a closed-loop system tied to repurposed oil wells. On discharge, stored thermal energy drives an expander and generator to return electricity to the grid or a local customer. Unlike geothermal generation, the concept does not extract naturally occurring underground heat; unlike geological storage, it does not inject CO₂ into the formation.

Cruver is candid about the open engineering questions:

• Recoverable energy and thermal losses
• Charge/discharge performance
• Well integrity
• Environmental compliance
• Costs and reliability of integrated equipment

Each requires quantitative modeling and pilot validation. A Long Beach pilot would need agreement among the relevant owners and operators, regulatory permissions, engineering verification and project financing.

A court ruling and a new governor

The same week as the MOU, a court ruling intensified scrutiny of a major carbon-storage project, and California elected a new governor, Xavier Becerra, who campaigned on reducing electricity bills. Becerra's proposed "Power Hour" would give eligible households up to two free midday hours of electricity, shifting consumption toward periods of plentiful solar output. It remains a proposal, subject to program design and implementation.

For storage operators, the logic cuts the same way: absorb lower-cost electricity during favorable hours, then make dispatchable capacity available when demand rises later in the day.

Getting paid without producing power

That is the premise of Geo2Watts' GridValue™ concept. An accredited storage project could earn resource-adequacy or other capacity-related revenue for its dependable ability to deliver power when called — even when not generating. "Getting paid without producing power" is shorthand for compensated readiness, not income without performance, Cruver writes. Any revenue depends on meeting deliverability, duration, accreditation, contracting and dispatch obligations, and on location and commercial arrangements.

What does this change for operators of mature oil assets? Potentially, a path to a new asset class without building every project component from scratch. What decides what happens next: the CPUC's 6,000-megawatt procurement deadline for 2029–2032 delivery, and whether a Borehole Battery pilot in Long Beach survives engineering verification and regulator review.
