Type One is commercializing the stellarator fusion concept, the ultimate clean power source, and making it affordable and available to all MoreLess

Type One Energy Group is a company focused on developing and commercializing fusion energy through its optimized stellarator technology. Founded in 2019, the company's mission is to provide the world with sustainable and affordable clean power. The founding team consists of globally-recognized fusion scientists, including CEO Christofer Mowry, CTO Dr. Thomas Sunn Pedersen, Chief Scientist Dr. John Canik, and Chief Engineer Dr. David Anderson. These founders bring a significant track record from institutions like the Max Planck Institute for Plasma Physics, where they were involved with the Wendelstein 7-X stellarator, and the University of Wisconsin-Madison, known for the HSX stellarator. This collective expertise in building advanced stellarator fusion machines is combined with leadership experienced in scaling and commercializing energy technologies.

The company's core technology is the stellarator, a device that uses complex, twisted magnetic coils to confine plasma and create the conditions for nuclear fusion. Type One Energy's approach aims to overcome the traditional complexities of stellarator construction by leveraging advanced manufacturing, modern computational physics, and high-field superconducting magnets. This strategy is intended to create a more efficient and commercially viable fusion power plant. The company is pursuing its 'FusionDirect' development program, which is described as a partner-intensive and capital-efficient strategy aimed at delivering a fusion pilot plant within the coming decade. In 2023, Type One Energy announced a significant partnership with the Tennessee Valley Authority (TVA) and the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) to develop and commercialize its stellarator fusion technology, with plans to build its Infinity ONE prototype fusion machine at the Bull Run Fossil Plant in Clinton, Tennessee. The company has secured over $29 million in a first tranche of its Series A financing, led by Breakthrough Energy Ventures, TDK Ventures, and Doral Energy Tech Ventures.
