L’Abeille of RENAISSANCE
February 2026
“L’Abeille,” pronounced [la-bɛj] in French, means “the bee” in English, a symbol of diligence and collective effort under the Sun. Much like bees, our Renaissance Fusion team works together to develop a fusion machine inspired by the Sun. Even a honeycomb cell subtly echoes the shape of our stellarator.
In this L’Abeille of Renaissance newsletter, we provide our perspective on the evolving fusion market and update where Renaissance Fusion fits within the fusion value chain and this dynamic landscape.

Notes from the age of electricity
We are entering a new phase of the energy transition — one that is no longer driven only by decarbonization targets, but by physics and demand.
According to the IEA’s latest Electricity 2026 outlook, global electricity demand is now growing at roughly 3–4% per year, one of the fastest sustained growth rates in recent decades. In just three years, the incremental demand is projected to exceed the entire current electricity consumption of Japan.
AI, electrification of industry, and the expansion of data centers are converging into a single constraint: reliable, non-intermittent, emissions-free power at scale. AI is central to this shift. AI training clusters run at extremely high utilization rates. They are dense, geographically concentrated, and power-hungry. Hyper scalers are increasingly looking not only for renewable energy credits, but for predictable, non-intermittent supply with long-term price visibility.
This is the context in which fusion has re-entered serious strategic discussions, as a foundational technology for the age of electricity! As the World Economic Forum recently put it in Davos, fusion energy can provide the large amounts of reliable, emission-free power that advanced AI systems require. In turn, AI can accelerate the design, operation and commercialization of fusion itself. This creates a first-of-its-kind symbiotic relationship: a self-reinforcing cycle in which fusion enables AI and AI accelerates fusion’s path to scale.
These two technologies are beginning to co-evolve. The International Energy Agency also confirms this shift. In its State of Energy Innovation 2026, the agency describes fusion as a potentially transformative clean energy technology, though still at an early stage of development, and lays out clear commercialization milestones, including net energy gain, sustained operational performance, scalable fuel supply chains and strict measurement standards, underscoring that fusion is moving on its strategic agenda.
From science projects to national strategy
Over the past months, something important has shifted.
Fusion is no longer discussed only in laboratories and academic conferences.
It is increasingly framed as a matter of industrial leadership and energy sovereignty.
Germany has committed more than €2 billiontoward fusion development before the end of the decade, announced a number of fusion test plants and started work on a regulatory framework designed specifically for fusion, intentionally simpler and faster than nuclear fission licensing.
The message is clear: if fusion is to become real, the rules must evolve with it. Across the Atlantic, the United States is looking at fusion through a different lens: supply chains.
A recent assessment by the Special Competitive Studies Projecthighlights a growing concern that many critical fusion components, from materials to isotope like lithium-6, are not domestically controlled Fusion is being evaluated not only as an energy technology, but as a strategic capability embedded in materials, manufacturing, and industrial autonomy.
Meanwhile, China is taking perhaps the most integrated approach, aligning research institutes, AI-driven digital twins, advanced manufacturing, and state-backed capital within a coordinated ecosystem. The objective appears less about demonstrating physics first, and more about controlling the entire industrial stack. In the country, scientific research, industrial infrastructure, and capital are being deliberately woven together. AI-driven digital twins of reactors, large-scale materials and engineering laboratories, and patient venture capital are all parts of the same system. The goal is not only to make fusion work, but to do so independently, at speed, and at scale.
South Korea is following a similar logic. Its national fusion plan explicitly combines public funding, industrial participation, regional demonstration facilities, and AI-enabled reactor design. Notably, South Korea is maintaining fusion technology-diversified: tokamaks, stellarators, FRC, and alternative concepts are all being pursued in parallel. This is a conscious bet on learning speed over early lock-in.
Across these geographies,
the pattern is clear:
fusion is becoming an industrial race.
Within this race, one enabling layer repeatedly surfaces: high-temperature superconductors (HTS).
Magnetic confinement systems depend on field strength. Field strength depends on magnet performance. Magnet performance depends on superconducting materials that can withstand extreme mechanical and thermal stresses while remaining manufacturable at scale.Performance under high magnetic fields. Tape width. Yield. Cost. Mechanical stability. These are no longer academic questions; they are industrial bottlenecks.
What makes HTS particularly appealing is that it does not sit exclusively inside fusion. Recently, Microsoft Azure explored how high-temperature superconductors could transform power distribution inside next-generation data centers.
As AI clusters densify, traditional copper-based architectures face spatial and thermal limitations. Superconducting systems could enable compact, high-capacity, low-loss power delivery.
In other words, HTS sits at the intersection of fusion, grid modernization and AI infrastructure, among other applications such as advanced medical imaging. The development of scalable HTS manufacturing capability influences multiple exponential sectors simultaneously. This is why parts of the fusion value chain may generate meaningful spillovers long before grid-scale fusion plants are operational.
Another shift is more subtle but equally important: fusion is beginning to meet customers. Out of more than seventy fusion startups globally, only a small subset are pursuing full-scale power plants. Among them, several have already signed power purchase agreements. These contracts do not imply near-term electricity production. But they demonstrate that sophisticated buyers are willing to plan around future fusion capacity. That changes the psychology of financing. It anchors expectations. It informs sitting discussions. It shapes supply chains. It signals that demand is not hypothetical.
The question is gradually moving from “Will there be a market?” to “Who will industrialize first?”
This is where
Renaissance Fusion fits
Our stellarator architecture is built around wide, laser-engraved HTS modules formed into cylindrical building blocks.
By replacing intricate 3D coils with manufacturable 2D modules, we simplify production while preserving magnetic precision. The modular structure allows magnets, plasma performance, and liquid metal systems to progress in parallel, and supports faster, AI-driven design iteration.
While most fusion programs optimize plasma physics within highly complex machines, Renaissance Fusion is uniquely designed for manufacturability, parallel development, and rapid iteration from day one.
Crucially, several of the core engineering risks behind this architecture have already been retired. We have demonstrated hardware-scale engraving of copper and HTS, established in-house magnet construction capability, and successfully operated thick, flowing liquid metal at temperatures up to 700°C within an HTS magnet environment. These milestones address manufacturability, thermal integration, and plasma-facing stability, three of the historical constraints in stellarator development.
Fusion remains the long-term objective. But the enabling technologies, wide HTS manufacturing, advanced magnet systems, and high-temperature liquid metal control, are directly aligned with the broader industrial shift toward high-density, reliable electricity infrastructure. We are advancing our work on HTS dynamics.
Recently the commissioning of our first Physical Vapor Deposition (PVD) machine is live, enabling us to deposit two of buffer layers of the HTS architecture right here in our own facility. This is a concrete step toward differentiated, wide-tape architectures. In an age defined by electricity, control over the enabling materials stack matters as much as the reactor design itself.
This is the environment in which Renaissance Fusion is building.
Our stellarator is designed from the outset to be modular, scalable, and compatible with AI-driven development, allowing parallel progress across subsystems rather than monolithic iteration.
Meeting our teams in March
MIT Universal AI summit, March 23-24, Warsaw, PO, GMA.
First up, the MIT Universal AI Summit is happening in Warsaw on March 23–24. It's one of those places where AI and energy conversations tend to overlap in interesting ways, as our Head of Investor Relations will be giving a talk on how fusion energy can meet the growing electricity demands of future AI systems.
CERAWeek, March 23-2, Houston, US, SGU
Then, starting the same week, CERAWeek kicks off in Houston from March 23–27. If you follow energy, you already know, it's the big one. Our CEO will be there, and fusion is expected to have a real presence on the ground this year.
Two different events, same week. If you're attending either, come say hello!
