Independent expert panel completes review of Gauss Fusion’s power plant conceptual design

• Independent Panel of senior European fusion and industry experts, chaired by Prof. Dr. Hartmut Zohm (Max Planck Institute for Plasma Physics, IPP), concludes review of Gauss Fusion’s Conceptual Design Report (CDR).
• Review comes following Gauss Fusion’s CDR being handed over to the German Government in October 2025.
• The CDR sets out a comprehensive and integrated basis for the development of Gauss Fusion’s GIGA power plant – Europe’s first and only comprehensive conceptual design for a commercial fusion power plant.
• Gauss Fusion transitions from its conceptual design phase, to engineering phase right at the moment when German Chancellor Merz has publicly stated his ambition to see the world’s first fusion power plant built in Germany.

Gauss Fusion, the European Greentech company founded to build the continent’s first commercial fusion power plant, today announced the completion of an independent expert review, as part of a structured external assessment of how its fusion power plant concept design has been developed.

Led by senior European fusion and industry experts and chaired by Prof. Dr. Hartmut Zohm (Max Planck Institute for Plasma Physics, IPP), the Review Panel assessed the coherence, integration and industrial logic of Gauss Fusion’s first full conceptual design for a commercial fusion power plant. The Review Panel’s written report is being finalised and is expected to be completed before the end of January.

Examining the CDR against the engineering definition of a conceptual design phase – covering overall architecture, system interfaces, and credible conceptual solutions for major subsystems – the Review Panel recognised the value of Gauss Fusion’s plant-level perspective; its approach to developing a holistic view of the full power plant; and its application of a systems-engineering mindset consistent with industrial delivery.

The conclusion of this review comes at a critical time for both Germany and Europe – a moment when decisive action is needed to move fusion from ambition to industrial execution. For policymakers at all levels, the test will be whether structures are set up to enable first-of-a-kind power plant delivery. This will be determined by what policy frameworks emerge; how responsibilities between public authorities and industry are assigned; and the pace at which decisions are taken. Gauss Fusion’s independently reviewed, integrated conceptual design is a necessary foundation for that shift.

As the company looks ahead, the completion of this CDR review marks a clear transition for Gauss Fusion as it enters the engineering phase of its programme. This next phase will focus on detailed engineering work – including deepening design maturity, validating critical assumptions, targeted prototyping and qualification, strengthening system integration, and refining delivery pathways alongside industrial partners.

Milena Roveda, CEO, Gauss Fusion:

“This independent CDR review matters because it tests not just individual technical choices, but whether our programme logic holds together at plant level."

“Germany has set out an ambition to see a fusion power plant built. The question now is whether policy, governance and industrial frameworks are aligned with that objective. Completing an independently reviewed, integrated conceptual design is a necessary next step if that ambition is to translate into delivery."

“I would like to thank the panel for the seriousness and rigour they have brought to this review and look forward to what comes next.”

Frederick Bordry, Chief Technology Officer, Gauss Fusion:

“The value of this review is that it brings discipline to the engineering work ahead. We now move into our detailed engineering design phase with a clearer understanding of system interfaces, critical assumptions and where qualification and prototyping efforts must be focussed. That is how complex industrial technologies progress from concept to reality."

“I am truly proud of the work we have delivered, enabled by a team of 100 engineers from specialised European industrial companies – including many of our shareholders – all of whom have contributed to the delivery of the CDR and the technical work underpinning it.”

Prof. Dr. Hartmut Zohm, Chair of the Independent Review Panel:

“Throughout the review process, we found the team to be highly competent in their ability to respond to our detailed technical questions and open to discussing where uncertainties remain."

“The panel has approached this task as the review of a conceptual design, not a technical design, as defined by the Concurrent Engineering approach. On that basis, we observe that Gauss Fusion has developed a coherent, plantlevel concept and a systematic approach that reflects an industrial mindset."

“As with any first-of-a-kind industrial system, substantial detailed engineering and qualification work remains ahead.”

Christian Linsmeier, Chair, Strategic & Scientific Advisory Board, Gauss Fusion:

“This is the most comprehensive and integrated conceptual design effort I have seen at this stage of development."

“The review confirmed that the Gauss Fusion team has systematically thought through the full range of questions a power plant raises – even where solutions are still to be developed."

“That combination of industrial know-how and specialist engineering expertise is what gives credibility and confidence as the company transitions to its engineering phase.”
