Thea Energy lands $20M federal grant to build its magnets for fusion reactors

Thea Energy received a $20 million award from ARPA-E to expand production of its high-temperature superconducting magnets. The components are intended for use in the company’s fusion reactor technology.

The grant underscores continued U.S. government support for private-sector fusion development, especially enabling hardware that could shorten commercialization timelines. Scaling magnet production is a key step as fusion startups move from lab demonstrations toward more integrated reactor systems.
