FusionXInvest 2025: Reflections by Ryan Ramsey, First Light Fusion COO
Silicon Valley has always been a global epicenter of innovation, but at FusionXInvest 25, it became the beating heart of the future clean energy revolution.
The reason I love working in the fusion industry is the true sense of purpose; I enjoyed making a difference as Royal Navy submarine captain, and working at First Light provides a unique opportunity to do the same.
Last week’s FusionX Summit in Silicon Valley was a meeting of sector leaders that aren’t just talking about the future but actively building it. Conversations bridged the gap between science, industry, policy and investment. Companies at the cutting edge of fusion technology showcased their latest breakthroughs and progress, while supply chain leaders discussed the infrastructure needed to turn theory into reality. Government departments were actively engaging in discussions about policy, funding and the regulatory landscape that will shape the fusion economy. Policy underpins progress.
One of my main takeaways from the Summit was the critical role that AI can start to play in accelerating fusion development. From optimising plasma simulations to revolutionising diagnostics and control systems, AI is proving to be a critical enabler in bringing fusion energy closer to commercialisation. The synergy between cutting-edge computing and advanced physics is shortening timelines, improving efficiency and providing new insights that were previously out of reach. The iteration loop is faster as a result.
But beyond the technology and the deals being made, what stood out most of all was the sense of shared purpose amongst all of the business leaders, scientists, physicists and policymakers in the room. Fusion is no longer just a scientific challenge — it’s a commercial, industrial, and societal movement – with a huge amount of momentum behind it.
Yes, it’s difficult. Yes it can be costly and complex. But the potential benefits are untold and if realised will transform our economy, energy system and society – on a truly global scale.
‘It’s too far in the future’ you might think. But the reality is, much like us, many companies are already looking at early revenue generation to become self-sustaining – and thinking about how we can apply your technology to space, health and other sectors. I saw many examples of this at FusionX. Creating new partnerships, new markets and life changing technologies will drive this industry forward.
If FusionXInvest 25 is any indication, the fusion industry isn’t just growing—it’s accelerating. And with the right mix of technology, investment, and collaboration – limitless clean energy really is within reach.
As we all go back to our day jobs, I’m sure I’m not the only one to do so with a spring in my step, buoyed by our collective achievements, vision and ambition for the future of fusion.
