Type One Energy

Bringing the compact, economical stellarator fusion power plant to the grid through innovations in high-temp superconducting magnets and additive manufacturing.

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.

[Type One Energy @typeoneenergy]

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.

We are pleased to introduce the new Senior Vice President of Global Affairs at Type One Energy, Patricia Schouker.

Patricia joins us from the British Embassy in Washington, D.C., where she led the nuclear and fusion portfolio for the United Kingdom, advancing UK-US cooperation across government, industry and capital markets. She was the architect of the UK-US Technology Prosperity Deal and played a key role in advancing cooperation on fusion and fission regulation. Working with policymakers, regulators and companies on both sides of the Atlantic, she helped shape policy, build partnerships and support commercial deployment.

Chief Commercial Officer Anthony Harbridge says: “Patricia joins at an important point in Type One Energy’s growth as we move from demonstrating fusion technology to building the commercial, regulatory and industrial ecosystem required for future deployment.”

Patricia’s career spans government, the private sector and international institutions. Her expertise covers nuclear and fusion energy, electricity markets, oil and gas, energy security, critical infrastructure, cybersecurity and geopolitical risk. She is recognized as one of the energy sector’s 40 most influential individuals and is a frequent international media contributor on energy security and international economic affairs.

As Senior Vice President of Global Affairs, Patricia will lead Type One Energy’s global government, policy and regulatory engagement, building the partnerships and frameworks needed to enable commercial fusion deployment on a global scale.

Please join us in welcoming Patricia to our team!

Type One Energy has a new U.S. patent! 🎉

CTO Thomas Sunn Pedersen, and Co-Founder, VP & Engineering Fellow David Anderson recently invented the Large Island Backside Divertor (LIBD) for Type One Energy. This is an innovative (and now patented) approach to solving a long-standing problem that stellarators have faced: inefficiencies in removing impurities. These impurities reduce fusion efficiency and require more frequent component replacement.

The LIBD patent uses large magnetic islands to guide the outflowing unburnt deuterium-tritium fuel for re-injection, fusion ash (helium), and impurities to the backside of a divertor structure embedded into the large island. This approach is designed to improve particle removal efficiency, resulting in more optimal fuel density control and purer plasma to enhance fusion efficiency and more durable components in our stellarator.

Congratulations to Thomas, David, and the entire Type One Energy team!

Commercial fusion will not be delivered by one company or one country acting alone. It requires strong supply chains, a skilled workforce, supporting regulation and sustained cooperation between governments, utilities, investors, and industry.

This deepening partnership between the United Kingdom and the United States, with leadership from the State of Tennessee and TVA, is an important step forward. Through our Project Infinity with TVA at Bull Run and the UK Infinity Fusion Consortium, Type One Energy and its partners are putting this imperative for cooperation into practice, building industrial capacity and establishing a clear path to commercial fusion power on the grid.

A first for #fusion. A first for Tennessee.

For the first time anywhere, Type One Energy has received a license for a fusion machine under a fusion-specific regulatory framework—a historic milestone for fusion energy and a major step forward for Project Infinity.

One step closer to bringing fusion from the drawing board to the grid! ⚡️

[Type One Energy @typeoneenergy]

For the first time anywhere, a fusion-specific license has been issued for a fusion power plant. Tennessee Governor Bill Lee today presented Type One Energy with the first license under its first-of-a-kind, fusion-specific regulatory framework.

This first-of-its-kind framework creates a clear regulatory pathway for fusion machines, helping pave the way for commercial fusion power plants to move from design to commercial operation. For Type One Energy, this license is a major step forward for Project Infinity, our planned fusion development at TVA’s Bull Run Energy Complex.

Fusion has spent decades in the realm of scientific research. With this milestone, Tennessee is helping create the regulatory foundation to bring it into the energy future.

Every engineering milestone brings commercial fusion one step closer to reality. The latest step came on June 16, when the FORGED-PFC team reached an important milestone with the successful completion of its Preliminary Design Review (PDR) at Type One Energy's Knoxville headquarters.

The review brought together technical experts from national labs and universities. Completing the PDR enables the project to move forward into detailed design and procurement.

Congratulations to the FORGED-PFC team who contributed to this achievement. We look forward to supporting the next phase of development!

@baking781 Our plans are evolving, but we will share more information about construction soon.

[Type One Energy @typeoneenergy]

A red-painted dot and a steel post. Not much to look at today, but on Friday Type One Energy and Tennessee Valley Authority marked a point of future historic significance: the center of our Infinity One stellarator.

Later this year, we break ground on Project Infinity at TVA’s Bull Run Energy Complex in East Tennessee, USA. We will begin construction of Infinity One—our engineering test bed and workforce training facility, and a critical step towards Infinity Two, our 400 MWe commercial fusion power plant.

Big things start from small points.

Our collaboration with @ORNL continues! Yesterday, we signed a technology licensing agreement— giving us access to ORNL-developed cryogenic pellet fueling technologies for use in high-performance fusion plasma operations.

“Fueling the fusion reaction with high repetition and high reliability is one of the most essential technologies for continuous generation of fusion power.” said Dr. John Canik of Type One Energy.

We look forward to leveraging this technology as part of Project Infinity at TVA's Bull Run Energy Complex in East TN.
