Helion, a fusion energy startup based in Everett, Washington, has achieved a significant milestone in its fusion power development efforts. The company’s Polaris prototype reactor recently reached a temperature of 150 million degrees Celsius, positioning Helion to potentially establish a commercial fusion power plant in the near future.
According to Helion’s CEO, David Kirtley, the use of deuterium-tritium fuel, a hydrogen isotope mixture, has led to a substantial increase in fusion power output in the form of heat within the Polaris reactor.
As Helion competes with other fusion energy companies to bring clean, limitless energy sources to the market, investor interest in the technology has surged. Recent funding rounds by Inertia Enterprises, Type One Energy, and Commonwealth Fusion Systems underscore the growing financial support for fusion energy ventures.
Unlike many competitors targeting electricity grid integration in the early 2030s, Helion has set a goal of supplying electricity to Microsoft by 2028 through its upcoming commercial reactor, Orion. This accelerated timeline reflects the company’s commitment to advancing fusion technology efficiently.
Each fusion startup, including Commonwealth Fusion Systems, faces unique challenges in achieving optimal plasma temperatures for successful fusion reactions. Helion’s achievement marks a significant step forward in the race towards practical fusion power applications.
