Fusion Power's Next Frontier: AI-Driven Control Systems

The Foundation of a New Energy Era

When Federico Felici and Jonas Buchli first recognized the potential in fusion power, they weren't looking for a breakthrough discovery. They were responding to a clear and persistent need that had been overlooked by the industry: the lack of standardized control systems for fusion reactors. This wasn't just an engineering challenge — it was a human one. The founders, both seasoned in their own right with deep roots in experimental physics and AI development, understood that innovation in this field would require more than just technical prowess; it demanded a keen sense of what the industry actually needed.

I've long believed that the most impactful business models are those that solve real-world problems — not just theoretical ones. That's exactly what Fusionality is doing. By identifying a gap in the supply chain for fusion startups, Felici and Buchli have positioned themselves to support an emerging industry that has the potential to reshape global energy dynamics.

The Current State of Fusion Power Development

Fusion power has long been hailed as the holy grail of clean energy — a solution that could provide unlimited, safe, and carbon-free electricity. But despite decades of research, the path from laboratory to commercial application remains steep. One major bottleneck is the complexity of control systems required for maintaining fusion reactions.

As Felici noted in our conversation, many fusion startups are forced to develop control systems from scratch, often duplicating work that could be standardized across platforms. "Across the industry, many companies make their own control systems from scratch," he explained. "But actually, 80% of each company's control system is really exactly the same."

This inefficiency not only delays development timelines but also increases costs and reduces the overall effectiveness of research efforts. It's a familiar pattern in emerging technologies — the early-stage chaos of custom solutions that eventually consolidate into more robust, scalable systems.

Building on DeepMind's Legacy

Felici and Buchli's journey to Fusionality is not accidental. Their backgrounds reflect a convergence of cutting-edge AI development and fusion research that positions them uniquely in the space. Felici spent time at EPFL, working with experimental tokamaks — donut-shaped devices used to study fusion power — while Buchli was part of Google DeepMind's team that applied machine learning to complex scientific problems.

This experience gave them deep insight into both the physics and computational challenges of fusion. More importantly, it provided a framework for thinking about how AI can enhance rather than replace traditional engineering approaches. "I wouldn't be somebody who advocates for AI to take the role of controlling the entire fusion reactor," Felici said. "Today, AI is more likely to complement or enhance or optimize parts of the system."

For those familiar with AI's application in complex systems, this is a pragmatic approach — one that acknowledges both the promise and limitations of artificial intelligence. In fusion power, where safety and precision are paramount, the integration of AI must be carefully considered.

Strategic Focus: Magnetic Confinement

Fusionality's initial focus on magnetic confinement systems is strategic. Magnetic confinement uses powerful electromagnets to contain and shape plasma — a superheated gas that is essential for fusion reactions. While not the only approach, it's one of the most promising paths to commercial viability.

The startups working in this space are numerous and ambitious: Commonwealth Fusion Systems, Realta Fusion, Proxima Fusion, and Type One Energy are all pushing forward with magnetic confinement designs. Each has its own approach and engineering breakthroughs, but they all face similar challenges when it comes to control systems.

"We start with a few of these blocks and then we build out more," Felici explained, referring to their approach of developing modular components that can be adapted to various reactor designs. "We have the ambition to serve the really wide range of technology that you need to operate a fusion reactor."

This modular approach is crucial. It allows startups to focus on what makes their design unique — the plasma physics, fuel types, or containment structures — while relying on standardized components for control systems.

The Business Case for Fusionality

Fusionality's pre-seed funding of $3.7 million (CHF 3 million) is modest by venture capital standards, but it signals a clear vision and a growing market need. With a team of seven people, the company has the flexibility to build quickly and iterate based on feedback from fusion startups.

The investment comes from FoundersFund and Playfair, both of which have a track record of supporting early-stage companies in emerging sectors. This is a sign that investors are beginning to recognize the potential of fusion power — not just as a futuristic dream, but as a near-term business opportunity.

In our rapidly changing energy landscape, where climate action is increasingly urgent, the role of startups like Fusionality becomes even more critical. They're not just building technology; they're building the infrastructure that will allow clean energy to scale effectively.

Looking Forward: The Path to Commercialization

While fusion power is still in its early stages, there are signs of momentum. The industry is growing, and companies like Fusionality are helping to accelerate that growth by providing the foundational tools needed for success.

However, challenges remain. Regulatory frameworks, public funding, and investor patience all play roles in how quickly fusion energy can transition from lab to grid. But the work being done by teams like Felici's is critical — it addresses real industry bottlenecks that have been holding back progress.

What's particularly encouraging is how this work intersects with broader trends in AI and clean energy. The convergence of these two fields suggests a future where intelligent systems play a central role in energy production — a future we're already beginning to see in startups like Fusionality.

The Human Impact

Ultimately, fusion power is not just about generating electricity; it's about changing the way we live. As someone who has spent years tracking economic shifts and their human impact, I've seen how technological innovation can be a force for good — but only when it's grounded in real-world needs.

Fusionality's approach reflects that understanding. Rather than chasing headlines or theoretical advances, they're solving practical problems that matter to the people who will use this technology. In doing so, they're not just building control systems; they're building a pathway toward a sustainable energy future.
