Type One Energy

Developing stellarator fusion energy — a radically different and more stable approach to clean, unlimited power. Backed by some of the world's most respected deep tech investors, tackling one of the most important engineering challenges of this century.

Type One Energy is accelerating the path to safe, reliable, carbon-free power through breakthrough stellarator fusion technology. The company integrates advanced research with practical engineering to develop fusion as a viable commercial energy source, addressing global clean power needs.

Why we invested

The world needs roughly 20,000 GW of new baseload clean power to reach net zero, and nothing currently on the horizon can deliver it at scale. Type One Energy is building a commercial stellarator fusion reactor, the most mature and technically credible path to steady-state fusion power, with a founding team that designed and operated two of the world's best-performing stellarators, including the billion-dollar W7-X project at the Max Planck Institute. The physics risk is largely retired. What remains is an engineering challenge, and T1E has the team, the IP, the US government backing, and an exclusive licence to MIT's next-generation HTS cable to execute it. This is a moonshot, and we knew that going in. We backed it because the team is irreplaceable, the opportunity is once-in-a-generation, and we believe New Zealand should have a seat at the table when fusion changes the world.
