Helion Energy, founded in 2013, is a pioneering company in the nuclear fusion sector, headquartered in Everett, Washington. The company was established by a team of innovators including David Kirtley, John Slough, Chris Pihl, and George Votroubek, with a mission to build the world's first commercially viable fusion power plant, delivering clean, safe, and abundant energy. Helion aims to revolutionize energy production by harnessing fusion, the process that powers the sun, to create zero-carbon electricity. While specific employee counts are not publicly available as of the latest data, the company has grown significantly in recent years, reflecting its ambitious goals and increasing investment.
Helion Energy remains a private company, with no public ticker symbol, and has attracted substantial attention from investors and industry partners due to its innovative approach to fusion energy. Its focus on developing a practical and scalable fusion solution sets it apart in the clean energy landscape, positioning it as a potential game-changer in addressing global energy demands and climate change challenges.
### Key Products and Technology
Helion is focused on a singular, groundbreaking technology for fusion energy production. Below is a detailed overview of their primary system:
- **Name and Type**: Helion Fusion Generator (Field-Reversed Configuration (FRC) Fusion Reactor)
- **Technical Specifications**: Helion's design targets a power output of approximately 50 MWe per unit initially, with plans to scale to larger capacities such as 500 MWe for industrial applications. The system operates by compressing plasma to achieve fusion conditions, recovering energy directly as electricity, which offers potential efficiency advantages over traditional heat-to-electricity conversion methods.
- **Fuel Type or Energy Source**: Helion uses a deuterium-helium-3 (D-He3) fuel mix, which is safer and produces minimal radioactive waste compared to traditional nuclear fission or other fusion approaches using deuterium-tritium. Helium-3 is rare on Earth but can be produced within the reactor, and deuterium is abundant in seawater.
- **Key Differentiators**: The FRC approach allows for a more compact reactor design compared to tokamak or stellarator systems, potentially reducing costs. Direct energy conversion bypasses the need for steam turbines, improving efficiency and simplifying infrastructure. Additionally, the D-He3 fuel cycle minimizes neutron production, enhancing safety and reducing long-term radioactive waste.
- **Development Stage**: Helion is in the advanced prototype and pre-commercial stage. The company has built and tested multiple prototypes, with their latest, Polaris, demonstrating significant progress. Construction of their first commercial power plant, Orion, has begun in Malaga, Washington, as of mid-2025, targeting operational status by 2028.
- **Target Customers**: Helion focuses on technology companies with high energy demands (e.g., Microsoft, their first announced customer), industrial manufacturers like steel producers (e.g., Nucor), and utilities seeking clean baseload power.
### Regulatory and Licensing Status
Helion Energy operates in a regulatory environment that is evolving to accommodate fusion energy, distinct from traditional nuclear fission. In May 2025, Washington State passed House Bill 1018, classifying fusion as a clean energy source and legally distinguishing it from fission, which enabled Helion to pursue local permitting for its Orion power plant site in Chelan County [World Nuclear News](https://www.world-nuclear-news.org/articles/helion-begins-work-on-fusion-power-plant). This legislative milestone is a significant step forward, as it streamlines the approval process compared to the more stringent Nuclear Regulatory Commission (NRC) oversight required for fission reactors.
As fusion technology is relatively new, the NRC and other [[Federal|federal]] bodies are still developing specific frameworks for licensing commercial fusion plants. Helion is in a pre-application phase for federal regulatory engagement, working closely with state and local authorities for the Orion project. Key upcoming milestones include completing environmental assessments and securing final permits for construction and operation. The estimated timeline to first commercial deployment remains 2028, as announced by Helion, though some industry experts express skepticism about the feasibility of this ambitious target [MIT Technology Review](https://www.technologyreview.com/2023/05/10/1072812/this-startup-says-its-first-fusion-plant-is-five-years-away-experts-doubt-it/).
