Thea Energy is pursuing the stellarator path to fusion energy. Their approach is to build stellarators using only planar high-temperature superconducting (HTS) coils. They plan to first build Eos, a stellarator utilizing their planar coil stellarator architecture to generate neutrons and operate in steady state. Beyond Eos, Thea plans to develop Helios, a larger, electricity-producing stellarator.

Eos

Eos image
Description

Thea Energy's "Eos" large-scale integrated stellarator facility will create steady-state fusion using the Company’s simplified planar coil magnet architecture. Eos leverages arrays of mass-manufacturable, superconducting magnet hardware and software-based control systems. Eos derisks Thea Energy’s first commercial fusion power plant, "Helios", and is anticipated to begin operations in 2030.

Helios

Helios image
Description

Thea Energy's "Helios" is a 400 MW fusion power plant that leverages the Company's proprietary planar coil stellarator architecture and will provide abundant fusion energy to the electrical grid. Helios combines the inherent benefits of the stellarator, including steady-state operation and high efficiency, with a practical maintenance scheme enabled by the simple, programmable magnet hardware.Thea Energy plans to operate Helios in the 2030s.
