Helion hits 150 million °C milestone in fusion energy race
Fusion startup Helion has achieved a major scientific milestone, reaching 150 million degrees Celsius in its Polaris prototype device. This temperature threshold is critical for sustaining nuclear fusion reactions and positions Helion closer to its 2028 goal of delivering commercial fusion power. The company has a power purchase agreement with Microsoft and aims to be the first private firm to produce electricity from fusion. Helion uses a unique magneto-inertial approach, differing from tokamak-based designs used by other fusion initiatives.
A commercial fusion breakthrough would mark a paradigm shift in clean energy, with huge implications for technology, climate, and global power infrastructure.
