Investor brief
A pan-European industrial consortium aiming at 1 GWe stellarator power
Executive Summary
Gauss Fusion is a pan-European public-private consortium of industrial heavyweights — Bruker, Ansaldo, SIMIC, IDOM and others — targeting a 1 GWe stellarator pilot plant (GIGA) in the late 2030s. The consortium model aggregates capability that would be impossible for any single European startup.
Strategic Thesis
Aggregate European industrial capability into a single coherent stellarator program rather than competing as fragmented startups.
The Problem
Global electricity demand is entering an unprecedented growth phase driven by AI infrastructure, data centers, transport electrification, industrial decarbonization, water desalination, and advanced manufacturing. Solar suffers intermittency, wind capacity-factor variability, natural gas carbon emissions, conventional nuclear cost and deployment speed, and batteries energy-density and duration limits. The world requires a new source of clean, dispatchable baseload energy. Fusion represents the ultimate energy source — the challenge is making it commercially practical.
GIGA — 1 GWe Stellarator Pilot Plant
GIGA targets the largest commercial fusion plant in the European pipeline: a 1 gigawatt-electric stellarator power plant designed to commercial utility specifications.
Industrial Consortium Model
Each member company brings a specific industrial capability — magnets, vacuum, cryogenics, balance-of-plant, plant engineering — under a single program.
GW-Class Stellarator
Large-aperture stellarator designed for utility-scale baseload generation.
European Licensing Pathway
Coordinated approach across EU regulators to define a stellarator licensing framework.
Fuel Strategy
Deuterium-Tritium
Standard D-T fuel cycle at utility scale.
Product Platform
GIGA Conceptual Design
1 GWe stellarator pilot plant concept.
Energy Conversion
Thermal (Rankine/Brayton)
Neutronic (D-T)
33–40% electrical
Deuterium-tritium fusion releases ~80% of its energy as 14.1 MeV neutrons, which deposit their kinetic energy in a surrounding blanket. The heat drives a conventional steam (Rankine) or supercritical-CO₂ (Brayton) turbine.
Conversion chain
- 1D-T plasma
- 214.1 MeV neutrons (80%) + 3.5 MeV alpha (20%)
- 3Neutrons → lithium-bearing blanket (heat + tritium breeding)
- 4Heat → steam/CO₂ turbine → electricity
The most thoroughly understood fusion fuel cycle, highest cross-section at achievable temperatures, and proven back-end engineering (steam turbines are 19th-century technology). Trade-offs: neutron-induced materials damage, tritium handling, ~33–40% Carnot-limited efficiency.
Economic Vision
Direct utility-scale plant means utility-scale economics — competing head-to-head with combined-cycle gas and large nuclear from day one.
Vision
A single coherent European stellarator program rather than fragmented startups.
Mission
Deliver the world's first GW-class stellarator power plant.
Engineering Bottlenecks

Milestone Timeline
2022
Consortium founded
The description above reflects Gauss Fusion's publicly stated technology goals, roadmap and architecture. Many elements — particularly net-energy gain at scale, advanced fuel cycles, and grid-relevant economics — remain ambitious objectives that have not yet been demonstrated commercially anywhere in the fusion industry. Forward-looking statements should be treated as engineering targets, not certainties.
