Bill Gates-backed startup Type One Energy secures $87m
Type One Energy, a US-based fusion power startup, has raised US$87 million through a convertible note, according to sources cited by TechCrunch.
This brings the company’s total venture funding to over US$160 million as it works toward a US$250 million series B at a reported US$900 million pre-money valuation.
Previous investors include Bill Gates’ Breakthrough Energy Ventures, Doral Energy-Tech Ventures, and TDK Ventures.
Type One Energy uses a magnetic confinement approach called a stellarator for its fusion technology.
In 2025, the company reached an agreement with the Tennessee Valley Authority to place its first commercial fusion power plant, Infinity Two, at the former Bull Run Fossil Plant site in Tennessee.
The plant is planned to generate 350 megawatts of electricity and may begin operations in the mid-2030s, according to the company.
Instead of building and running the power plants itself, Type One Energy plans to sell its technology to utilities and power providers.

🧠 Food for thought
Implications, context, and why it matters.
Regulatory path for mid-2030s deployment remains unclear despite site agreement
- On December 11, 2024, U.S. Nuclear Regulatory Commission (NRC) staff sent a draft fusion rule to the Commission 1, with a proposed rule by May 2025 and a final by October 2026 for a byproduct material framework that covers stellarators 2.
- The ADVANCE Act (Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy Act) put ‘fusion machine’ in the Atomic Energy Act’s (AEA) byproduct material definition 31. NRC plans criteria for when a fusion system is a ‘utilization facility’ plus alignment across NRC and Agreement State jurisdictions, where possession of byproduct material from fusion can fall to the state under AEA Section 274 23.
Superconductor makers should secure offtake deals for stellarator coil orders
- Stellarator plants need complex high-field coils. REBCO (rare-earth barium copper oxide) high-temperature superconducting (HTS) tapes underpin compact fusion, with global output above 5,000 km a year, while grids and MRI also draw from that pool 4.
- Compact fusion has pushed growth in PLD-REBCO (pulsed laser deposition REBCO) tapes 4. Several fusion firms aim for the 2030s 2, while grid upgrades add pull, so tape makers face rising demand plus scaling hurdles 4.
- Suppliers of superconductors and coil fabricators can lock in offtake (long-term purchase) deals with fusion developers. Shanghai Superconductor Technology (a China-based HTS supplier), Fujikura (a Japan-based electrical and electronics manufacturer), plus emerging players shifting to PLD technology can co-develop stellarator tape specs and reserve capacity before wider builds 4.
