Global Fusion Supply
Chain Company
A pure-play partner for the fusion industry on a mission to accelerate fusion companies by bridging world-class science with deployable, industry-ready solutions.
What We Do
Within the I&C domain for the fusion industry, we work at the very core, bringing together deep experience in plasma simulations, diagnostics, and plasma control into reliable, fully integrated solutions where every detail is taken into account.
Tokamak integrated modeling
We partner with MCF device builders from their first step through implementation, providing end-to-end design and integrated modeling across the full system lifecycle.
In 2023–2026, we performed hundreds of specialized simulations, 10+ feasibility studies of new tokamaks, and enabled the journey of 4 tokamak startups.
Learn moreModular diagnostics platform
End-to-end diagnostics for next-generation MCF systems and future Fusion Power Plants in one seamless I&C solution, fully supported and supply-chain ready.
Essential measurements and plasma parameters, captured and delivered through one integrated data acquisition system to control and safety.
Learn moreSpecialized fusion software
Our team combines experienced plasma scientists with professional software engineers to develop high-quality software for integrated modeling and design, fusion data visualization and analysis, plasma parameter prediction and control, etc.
Explore NSFsim, our advanced tokamak simulator, and other software.
Learn moreMachine Learning Solutions
AI and ML are essential to match the complexity and speed of fusion. We develop RL-based plasma controllers, neural network reconstruction, surrogate models, and discharge scenario builders — grounded in physics and validated on real devices.
Our ML engineers work hand-in-hand with plasma physicists, with results demonstrated on DIII-D and other devices.
Learn moreFusion Experts
Our team comprises plasma physicists, fusion engineers, software developers, and machine learning specialists — united by a shared passion for making fusion energy real. Based across the EU and UK, with headquarters in Luxembourg.
Why Next Step Fusion?
We bring together expertise across plasma science, fusion engineering, diagnostics hardware and software, software development, data science, plasma control, and machine learning — all under one roof, all focused on fusion.
Fully fusion-focused
100% of our work is dedicated to fusion energy. No diluted priorities — just deep, sustained expertise in the field. And we simply love fusion.
