Commonwealth Fusion Systems 获美国商务部 $85M CHIPS Act 拨款开发聚变能半导体

Commonwealth Fusion Systems (CFS) announced on Thursday that it would receive $85 million from the U.S. government to develop advanced chips for the fusion power industry.

Fusion power startups have been racing to complete their first demonstration devices, with CFS aiming to turn on its Sparc reactor sometime next year. But building one reactor is just a proof point. If fusion startups want to build dozens of commercial power plants, they’ll need more durable power electronics and a robust supply chain.

The new CHIPS Act award from the Department of Commerce, which also grants the government a stake in CFS, will help boost R&D and manufacturing capacity for semiconductors in the U.S., the company said.

“Ultimately, that means a more capable, economical power plant and a stronger U.S. supply chain to build it,” Brandon Sorbom, co-founder and chief science officer at CFS, wrote in a blog post.

CFS’s award will go toward supporting five different initiatives.

The first is the advancement of silicon carbide power electronics. The semiconductors are widely used to manage high voltages, and they’re found in everything from LEDs and EVs to cell phone base stations and data centers. It’s also used in fusion machines, where intense bursts of electricity are used to drive the superconducting magnets that confine plasma inside a reactor.

CFS will also use the award to develop next-generation radio-frequency power generators, which the company uses to heat fusion fuel, and advanced electronics that will enable faster control of the reactor and be hardened against radiation. The latter could help extend the lifespan of electronics within a fusion power plant, reducing operating costs.

Lastly, CFS plans to use part of the CHIPS award to adapt AI hardware like GPUs and TPUs for power plants.

“The funding would help improve the U.S. chip and power electronics industries at the same time it accelerates fusion energy’s progress toward the electrical grid,” Sorbom said.
