Helion Reaches 150 Million Degree Plasma Milestone
|
7.1
In late June 2026, Helion Energy announced its Trenta prototype reached plasma temperatures exceeding 150 million degrees Celsius after more than 14,000 high-power shots. The company says the achievement advances its field-reversed-configuration (FRC) pulsed approach and informs Polaris, a seventh-generation system intended to demonstrate net electricity by 2028 under a Microsoft power-purchase agreement. The milestone addresses temperature challenges but not yet net energy.
Scoring Rationale
Major verified prototype temperature milestone with industry funding and timelines; limited by lack of net-energy demonstration.
