Overview
- Thea Energy announced Wednesday that it closed an oversubscribed $100 million Series B led by U.S. Innovative Technology Fund with participation from multiple strategic investors.
- The company plans to use the capital to expand production of its rectangular, software‑tuned “pixel” magnets and open a second manufacturing facility in northern New Jersey.
- Thea says the funding will let it start construction of Eos, a power‑plant‑relevant stellarator demonstrator, next year as part of a roadmap that targets Eos completion by 2030 and a commercial Helios plant by 2034.
- Engineers have modified the original planar‑only concept by adding 12 larger external magnets so more than 300 smaller planar magnets now fine‑tune the field, a change that narrows some of the company’s claimed manufacturing advantages.
- The round strengthens Thea’s position in a crowded fusion race and follows regulatory progress, including a DOE preconceptual design milestone, but the approach remains unproven at reactor scale and faces technical, siting, and offtake risks.
