Helion We're building the world's first fusion power plant and creating a new era of plentiful, zero-carbon electricity from fusion. Enabling a future with unlimited clean energy

EVERETT, WASHINGTON – MAY 10, 2023 – Helion Energy (Helion) today announced an agreement to provide Microsoft electricity from its first fusion power plant. Constellation will serve as the power marketer and will manage transmission for the project.

Helion Energy, a clean energy company committed to creating a new era of plentiful, zero-carbon electricity from fusion, today announced the close of its $0.5 billion Series E, with an additional $1.7 billion of commitments tied to specific milestones.

Answers to FAQs like: What is different about Helion's approach to fusion? How will Helion generate electricity? How much will fusion cost?

2021年11月5日 · The funding includes the opportunity for an additional $1.7 billion dollars tied to Helion reaching key performance milestones. The capital will be used to complete the construction of Polaris, Helion’s seventh generation fusion generator.

Helion's magneto-inertial fusion technology combines aspects of magnetic and inertial confinement fusion for an ultra-efficient fusion solution. By directly capturing electricity, our approach provides a faster path to putting fusion electricity on the grid.

Helion’s record-breaking 6th fusion prototype. Trenta represents a significant step forward in the pursuit of clean, safe, and abundant fusion energy. It was the first privately-funded fusion device to reach commercially-relevant fusion conditions.

Helion Energy’s Trenta prototype merged and compressed high-Beta Field Reversed Configuration (FRC) deuterium plasmas to fusion conditions, reaching 9 keV total bulk plasma temperatures with operation above 8 keV ion temperature and 1 keV electron temperature.
