Our GIGA™ Platform
The system-level architecture for future stellarator power plants
GIGA™ provides the robust system-level architecture for Gauss Fusion’s future high-field stellarator fusion power plants.
It starts from the requirements of the complete power plant rather than treating individual technologies in isolation. Manufacturability, maintainability, operation and economics are considered as design requirements, with Gauss Fusion’s proprietary technologies developed within this wider system architecture. The platform is intended to support pragmatic, technology-agnostic choices where different technical routes remain available.
The GIGA™ Conceptual Design Report was completed in 2025 and independently reviewed by a panel of fusion and industry experts, establishing the architectural foundation for the next stages of engineering and technology development.
“This is the most comprehensive and integrated conceptual design effort I have seen at this stage of development.”
— Christian Linsmeier, Chair,
Strategic & Scientific Advisory Board, Gauss Fusion
Designing the plant as one system
A fusion power plant brings together the fusion device, magnets, heating, breeding and fuel-cycle systems, heat and particle exhaust, thermal systems, electrical generation, control, buildings, maintenance and supporting infrastructure. Decisions in one part of the plant affect many others.
GIGA™ is intended to make those relationships visible early, so that technologies can be developed against the needs of the complete plant. The system-level approach is intended to support power plants that can ultimately be manufactured, maintained and operated as industrial assets, not simply demonstrate plasma performance.
GIGA™ is being developed around long-life, maintainable power-plant systems, with plant lifetime and economics considered as design requirements rather than afterthoughts.
A conceptual foundation
Gauss Fusion completed the GIGA™ Conceptual Design Report in 2025. The report established a system architecture, principal requirements and an initial basis for the next stages of engineering and technology development.
The conceptual design was subsequently assessed by an independent panel of senior fusion and industry experts, chaired by Dr. Hartmut Zohm of the Max Planck Institute for Plasma Physics.
This work provides a foundation for further development. It is not a completed technical design, a construction commitment or evidence that all plant systems have been demonstrated.
Guiding technology development
GIGA™ helps Gauss Fusion identify which technologies have the greatest influence on plant feasibility, integration, manufacture, operation and maintenance.
The current programme concentrates on advanced high-field stellarator design, demountable magnets, tritium breeding, plasma exhaust and the fuel cycle.
Each programme is developed against system-level requirements and interfaces defined through GIGA™.
A staged route towards deployment
02
Demonstrate and integrate
Progress technologies and systems interfaces through staged industrial demonstration at increasing levels of scale.
03
Progress towards a first-of-a-kind power plant
Apply engineering evidence, technology capability and industrial supply chains to the development of a first-of-a-kind fusion power plant.
04
Enable subsequent commercial plants
Use the GIGA™ platform as the basis for future commercial fusion power plants, incorporating the learning and evidence generated through earlier stages.
A platform for industrial collaboration
By defining requirements and interfaces at plant level, Gauss Fusion can work with specialist organisations on individual systems while maintaining a coherent overall architecture.
Gauss Fusion is interested in partners able to contribute capital, engineering, technology, manufacturing capability, infrastructure and other strategic resources.
