Fusion startup Helion is developing new semiconductors that could double output of its power plants
Helion said Thursday it has received $175 million in federal funding under the CHIPS Act to research, develop and manufacture advanced semiconductors and power electronics for its fusion power plants. The three-year award comes from the Department of Commerce.
Those power devices currently lose about 5% to 10% of the electricity that passes through them. "If we can cut that loss in half, that's actually twice the power output of the fusion system," CEO David Kirtley told TechCrunch.
The money will help build automated module, packaging and testing capacity in Washington state, which Helion says will be the first U.S. line for this class of high-voltage, pulsed semiconductors. "There are no U.S. manufacturers right now that do it," Kirtley said.
Helion is racing to finish its first plant, Orion, to start supplying Microsoft with electricity in 2028. It also announced a new $50 million private investment from an undisclosed investor, bringing its total raised to more than $3.2 billion.
