SACRAMENTO, CA — California has awarded General Atomics a $20 million tax credit to advance the development of commercial fusion energy, state officials announced Thursday. The funding, part of the California Competes Tax Credit program, will support the design and construction of a national-scale fusion materials testbed in San Diego. This new Blanket Component Test Facility (BCTF) is a critical step toward developing the robust components needed for a future fusion power plant.

The BCTF will be a unique facility designed to simulate the extreme conditions inside a fusion reactor. It will use a powerful electron beam to generate intense heat fluxes, allowing researchers to test the durability of specialized materials and components. The primary focus will be on the fusion “blanket,” a critical system that surrounds the plasma, converts neutron energy into heat, and breeds the tritium fuel necessary to sustain the fusion reaction.

The BCTF will be a unique facility designed to simulate the extreme conditions inside a fusion reactor.

Administered by the Governor’s Office of Business and Economic Development (GO-Biz), the tax credit is part of a state initiative to retain and attract high-value employers. The total estimated cost for the BCTF project is $46 million, with the state's contribution representing a significant investment in securing California's role as a leader in the burgeoning fusion industry. GO-Biz Director Dee Dee Myers highlighted the award as a key part of the state's strategy to foster innovation and high-paying jobs.

General Atomics, a long-standing leader in magnetic confinement fusion research, will build the facility at its main campus in San Diego. Anantha Krishnan, senior vice president of GA’s Energy Group, stated that the BCTF will be one of the largest and most capable facilities of its kind in the world. Its construction addresses a major gap in the U.S. fusion research and development infrastructure, providing a domestic platform for qualifying materials essential for a fusion pilot plant.

The facility's primary mission is to subject blanket prototypes to thousands of hours of high-temperature, high-stress cycles that mimic the operational demands of a commercial fusion power plant. Data from these tests will be crucial for validating designs and ensuring the reliability of components that must perform flawlessly for years under some of the most intense conditions created on Earth. This materials science work is widely seen as a key bottleneck on the path to putting fusion electricity on the grid.

With the funding now secured, General Atomics will move forward with the final design and construction phases for the BCTF. The project timeline and specific operational start date have not yet been finalized. Progress on the facility will be closely watched by the broader fusion community, as its capabilities will be vital for informing the design of the first U.S. fusion pilot plants, which are anticipated to be developed in the 2030s.
