Thea Energy has announced collaborations with NVIDIA, Synopsys, Argonne National Laboratory and Princeton Plasma Physics Laboratory to develop a digital twin of its Helios stellarator fusion power plant. The initiative supports the US Department of Energy's Genesis Mission, which aims to accelerate fusion power development using artificial intelligence. The digital twin will integrate AI and computational tools to analyse vast datasets, rapidly evolve plant designs and test system operations more efficiently than traditional methods. NVIDIA will build the platform using Omniverse libraries, whilst Synopsys will provide multiphysics simulation expertise for the breeding blanket system. Thea Energy's planar coil stellarator architecture uses AI for software controls to continuously optimise the system. The company aims to deliver fusion power by 2035, using the digital twin to shorten development cycles and reduce capital requirements.

Thea Energy, a fusion power startup advancing stellarator technology, has raised $100 million in an oversubscribed Series B round led by US Innovative Technology Fund. General Innovation Capital Partners and Linse Capital participated, alongside existing investors including Lowercarbon Capital and Prelude Ventures. The Kearny, New Jersey-based company will use the funding to expand magnet manufacturing capacity, including adding a second facility, and construct "Eos", a large-scale integrated stellarator system. Thea Energy plans to select a site for Eos this year whilst doubling its team size. Founded in 2022 as a Princeton University spin-out, Thea Energy recently became the first company to receive US Department of Energy certification for its Helios power plant preconceptual design milestone. The company aims to begin construction of its first commercial power plant before 2030.

Thea Energy, a Kearny-based company, is advancing its fusion power goals with significant backing, including a recent fellowship from Amazon Web Services and the International Research Centre on Artificial Intelligence. A spinout from Princeton Plasma Physics Laboratory and Princeton University, Thea Energy focuses on commercializing stellarator fusion energy. Since its 2022 founding, the company has raised $30 million in investor funding and received additional non-dilutive funding from the U.S.
