Novatron

What Novatron does

Novatron Fusion Group AB is a Stockholm-based, privately held fusion energy developer founded in 2019 (officially launched in December 2022) that is commercializing the NOVATRON reactor — a proprietary magnetic mirror fusion design invented by CTO and co-founder Jan Jäderberg. The architecture is the world's first stable axisymmetric mirror machine, using a unique concave magnetic field geometry, triple-force plugging technology for axial confinement (claimed to deliver a 1000-fold efficiency improvement over conventional mirror designs), and conventional copper magnets to achieve high-beta plasma operation with weaker — and therefore less capital-intensive — magnetic fields. The product roadmap runs from the X0 experimental test rig at KTH (first plasma January 2024) through the NOVATRON 1 prototype inaugurated in June 2025 at the KTH Alfvén Laboratory (described as the EU's first private, fully integrated fusion plasma system), toward the planned NOVATRON 3 pilot reactor targeted for construction in the Nordic region during the 2030s, with a stated goal of commercial grid delivery before 2040.

The company operates a partnership-driven, pre-commercial business model with no disclosed product pricing or end-customer revenue. Capital sources include a EUR 5M seed round (August 2023, led by Climentum Capital), a EUR 3M EIC Pathfinder grant for the TauEB project (December 2024), and a EUR 13M Series A1 led by Nordic energy operator St1 (March 2025), aggregating to roughly EUR 22M of disclosed funding. Strategic alliances span academic partners (KTH Royal Institute of Technology as anchor, UKAEA, Kharkiv Institute of Physics and Technology), pan-European industrial networks (EIT InnoEnergy), industrial and supply-chain partners (St1, Studsvik AB, Freemelt AB, Oxford Sigma), and ecosystem bodies (Fusion Industry Association, The Fusion Cluster UK). The customer base in the commercial sense is effectively non-existent at present — the company serves governments, energy companies, and research institutions as development partners rather than paying end customers, with St1 acting as the flagship strategic anchor.

The GTM is sales-led and event-driven: enterprise engagement with energy companies, governments (including the Director-General of ITER and the European Commission), and research institutions for partnership and funding development, complemented by active participation in and leadership of industry forums (Nordic Fusion Forum, Fusion Energy Forward, FUSION24, FusionXInvest) and PR-driven awareness building in outlets such as USA Today, Wall Street Journal, Financial Times (Sifted), and CNBC. The competitive positioning rests on the design simplicity of the NOVATRON concept — fewer complex systems, lower construction, operational, and maintenance costs versus tokamak and stellarator approaches, and continuous steady-state operation rather than pulsed — within a regulatory environment (Sweden in particular) that explicitly accommodates fusion reactors.

Core offering

Novatron Fusion Group develops the proprietary NOVATRON fusion reactor, a magnetic mirror-based concept featuring a unique concave magnetic field geometry and triple-force plugging technology for stable plasma confinement. The company is currently in pre-commercial stage, building prototypes such as NOVATRON 1 (N1) at KTH Royal Institute of Technology, with a planned pilot reactor (NOVATRON 3) targeted for the 2030s and grid-deliverable commercial fusion power targeted before 2040.

Product overview

Novatron Fusion Group is developing the NOVATRON fusion solution — a proprietary magnetic mirror-based fusion reactor technology. The core product is the NOVATRON design, which uses a unique concave magnetic field configuration and triple-force plugging technology for stable plasma confinement. The product portfolio includes the NOVATRON 1 (N1) prototype — the first private, fully integrated fusion plasma system in the EU, inaugurated in June 2025 — and the planned NOVATRON 3 pilot reactor targeted for the 2030s. The company is working to verify the reactor design for continuous steady-state fusion and ultimately generate power to the grid before 2040, targeting commercially viable and cost-effective clean energy production.
