TYPE ONE ENERGY

Type One started in 2019. The core founders were stellarator physicists from the University of Wisconsin-Madison.

David Anderson, Chris Hegna, and John Canik had designed, built, and run HSX, the world's first optimized stellarator. Brian Matthews and Randall Volberg rounded out the founding group.

Their belief was contrarian. For decades the fusion world poured money into the tokamak and treated the stellarator as a curiosity, because its magnets are nightmarishly complicated.

The founders thought that was a mistake. A stellarator does not need a big electric current running through the plasma, so it can run continuously and it does not blow itself off course the way a tokamak can.

In 2023 they brought in Christofer Mowry, who used to run General Fusion, to turn the science into a company. They also hired Thomas Sunn Pedersen, a leader from the W7-X project, as chief technology officer.

Type One makes no money yet. They are building machines, not selling power.

The plan is to build stellarator fusion plants and sell the electricity to utilities. Their first customer is lined up already.

The Tennessee Valley Authority, a giant public power company, wants to put a Type One plant on one of its old sites. They call their approach FusionDirect.

The idea is to be capital-efficient by leaning on existing suppliers and existing power-plant locations instead of building every single thing from scratch. Cheaper, faster, and with a buyer waiting at the other end.

Infinity One is the prototype stellarator Type One wants to build first, planned for the TVA Bull Run site in Tennessee. Infinity Two is the real prize, a first-generation 350 megawatt fusion power plant meant to feed steady electricity to the grid.

The technology underneath both is a stellarator built with high-temperature superconducting magnets shaped into complex non-planar coils. Modern supercomputing lets them optimize that twisted magnetic field in ways the original stellarator builders could only dream of.

Right now these are engineering programs, not products you can buy.

The smartest move Type One made was where they chose to build. Their first plant is planned for TVA's retired Bull Run coal site in Tennessee.

That site already has the grid connection, the cooling water, the trained workforce, and a community that wants the jobs back. You are not starting in an empty field.

You are recycling a dead coal plant into a fusion plant. They also pulled in Oak Ridge National Laboratory as a partner and grabbed money from Tennessee's state nuclear energy fund.

The coal-to-fusion story writes its own headlines, and it makes politicians and utilities comfortable. That is half the battle in energy.

Building a stellarator is brutally hard. The magnet coils are twisted 3D shapes that have to be manufactured to millimeter tolerances.

Germany's W7-X took roughly 19 years and over a billion euros to build, and it is only a research machine. It has never produced net energy.

Type One has to build something commercial, cheaper, and faster than that. On top of the engineering, there is the fusion curse itself.

No machine on Earth has ever produced more energy than it consumed in a steady, controlled way. Type One is targeting the mid-2030s.

In a field that has been twenty years away for sixty years, that is an aggressive promise.

Type One is backed by serious climate money. Bill Gates' Breakthrough Energy Ventures is the anchor investor and has led multiple rounds.

TDK Ventures, the arm of the Japanese electronics giant, is in. So are Doral Energy-Tech Ventures and Australia's Breakthrough Victoria.

Beyond the venture money, the company has lined up the Tennessee Valley Authority as a future customer and Oak Ridge National Laboratory as a research partner. Tennessee's state government has also chipped in through its nuclear energy fund.

That mix of private cash, a public utility, and a national lab is exactly what a fusion company needs to survive the long road to a working plant.
