Helion Energy is developing a novel pulsed magneto-inertial fusion system that differs significantly from traditional tokamak designs, aiming for smaller, more rapidly iterable, and manufacturable power generators.
The company's approach utilizes a deuterium-helium-3 reaction and direct energy conversion, which theoretically allows for over 95% efficiency in recovering magnetic energy and produces high-voltage DC power ideal for data centers.
Helion has achieved significant technical milestones, including reaching 100 million degrees Celsius, and has secured a landmark power purchase agreement with Microsoft to deliver fusion-generated electricity by 2028.
Fusion power is presented as inherently safe, with no risk of meltdown, no long-lived radioactive waste, and no potential for nuclear weapons proliferation, leading to a more streamlined regulatory pathway under the NRC's Part 30 statute for particle accelerators.
