Type One Energy

Type One Energy and @Kyotofusioneer have announced an agreement for Kyoto Fusioneering to supply 170 GHz, 1 MW-class gyrotron systems for the electron cyclotron heating (ECH) system of Infinity One at Tennessee's Bull Run Energy Complex.

These systems generate the high-power microwaves needed to heat plasma in stellarators, with deliveries scheduled for completion in 2029.

This partnership combines Type One Energy's stellarator expertise with Kyoto Fusioneering's gyrotron technology, helping build the industrial supply chain needed to deploy our planned 400 MWe Infinity Two commercial fusion power plant at scale.

We believe partnership is essential to commercializing fusion, and public-private collaboration is one of the most powerful tools for accelerating progress.

As a @ENERGY Fusion Milestone awardee and multi-time INFUSE recipient, Type One Energy is advancing critical R&D through two newly selected 2026 INFUSE projects with @UWMadison and @ORNL.

These partnerships also support investments in a world-class high-heat-flux testing facility at the Bull Run Energy Complex, developed in partnership with the State of Tennessee.

The DOE's new Science & Technology Roadmap provides a framework for accelerating fusion development and strengthening U.S. leadership. We thank Secretary Chris Wright for bringing industry, national labs, and government together around this shared vision.

Our Infinity Two fusion power plant will be designed to use deuterium-tritium fuel and breed new tritium as it operates. It's an elegant solution, but does every fusion power plant in a commercial fleet really need to produce tritium?

In the latest Journal of Fusion Science and Technology, our Senior Tritium Scientist & Tritium Plant Lead Mohamad Abdallah and other Type One Energy members explore a different approach. He envisions a coordinated fleet where some fusion power plants produce fuel and others produce power.

“We can start designing specific systems and thinking about commercial fleets of fusion reactors, and we can actually see a viable pathway to commercialize fusion.”

By specializing roles across a fleet of power plants, fusion could deploy faster, operate more efficiently, and unlock greater flexibility for the industry.

Thanks to our friends at @NYSE for featuring our $200M Series B financing round on the trading floor this week.

As a fusion technology provider and equipment manufacturer, we’re advancing the capital-efficient path to commercial fusion energy!

The round was co-led by Breakthrough Energy Ventures and Clutterbuck Capital, with participation from Lowercarbon Capital, Siemens Energy Ventures, SiteGround Capital and other new investors.

Today, Type One Energy announced the successful completion of our $200M Series B financing, co-led by @Breakthrough Energy Ventures and Clutterbuck Capital, with participation from new investors including @lowercarbon , @Siemens_Energy Ventures and SiteGround.

With this investment, we’re advancing our FusionDirect™ technology, progressing the design of our 400 MWe Infinity Two power plant at @TVAnews's Bull Run Energy Complex.

The timing is significant as this financing follows Tennessee’s granting of the initial fusion license for Project Infinity, establishing an important regulatory milestone for the project.

With new capital, strategic investors and a growing network of industrial partners, we’re continuing to move Project Infinity forward and building the foundation for fusion power at commercial scale.

We’re excited for what comes next.
