Helion wins $175 million to develop more efficient fusion power electronics
Helion has received $175 million in federal funding to develop and manufacture advanced semiconductors and power electronics for its fusion plants. The company says these components currently lose 5% to 10% of passing electricity, and halving those losses could, in its chief executive’s estimate, double a plant’s power output.
The three-year award will support production capacity in Washington State and research and development in Washington and Vermont, including work with GlobalFoundries. Helion is also raising a separate $50 million private investment and has raised more than $3.2 billion in total. The work will not be ready for its first plant, Orion, which Helion aims to complete in time to supply Microsoft from 2028, but could improve the efficiency of later plants.
In short
- Helion secured $175 million in federal funding for semiconductor work.
- The company says halving component losses could double power output.
- The research is intended to improve future plants, not Orion.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The award could help build domestic capacity in advanced power electronics and semiconductors, while supporting research that may reduce energy losses in future fusion plants. If the technology delivers the gains Helion expects, it could make later plants more productive and strengthen the case for fusion as a source of electricity.
The case against
The funding commits substantial public money to a company whose fusion plants have yet to demonstrate commercial operation, and the projected output gains are estimates rather than established results. Since the work will not benefit Helion’s first planned plant, critics could argue that its uncertain, longer-term returns should be weighed against other possible uses of federal support.
