Commonwealth Fusion Systems Teams Up with Siemens and Nvidia for Digital Twin to Transform Fusion Energy Development
Fusion energy has long been heralded as the key to a sustainable and limitless power supply, but progress in the field has often been hampered by complex engineering challenges and lengthy experimentation processes. To tackle these issues head-on, Commonwealth Fusion Systems (CFS), the world's leading private fusion energy company, has announced groundbreaking collaborations with tech giants Siemens and Nvidia. This joint effort aims to revolutionize the development of fusion energy through the creation of a high-fidelity digital twin of its SPARC machine, utilizing artificial intelligence (AI) and advanced digital tools.
In a recent announcement, CFS explained how this innovative initiative will harness a vast amount of data generated by the Siemens Xcelerator suite of industrial software. This portfolio includes cutting-edge tools such as the Designcenter NX, which aids in advanced product engineering, and Teamcenter for product lifecycle management (PLM). Through the integration of these technologies, CFS will efficiently create, organize, and manage designs and assemblies necessary for the SPARC fusion machine.
The digital twin will not only serve as a virtual replica of the SPARC machine but will also enable CFS to run simulations, test hypotheses, and conduct rapid comparisons between experimental outcomes and theoretical models. "By connecting all our data with Nvidia's Omniverse libraries and OpenUSD, we can provide a user-friendly interface for extensive modeling and simulation workflows," noted Bob Mumgaard, Co-Founder and CEO of CFS. This capability is set to significantly reduce the time typically required for manual experimentation, compressing years of research into just weeks of virtual optimization.
The collaboration with Nvidia is particularly exciting, as their Omniverse platform allows for high-fidelity simulations powered by AI. This means that as CFS progresses in its engineering efforts, the company will be able to tackle incredibly complex physics problems more effectively, thus shortening the timeline to achieve clean power derived from fusion. Rev Lebaredian, Vice President of Omniverse and Simulation Technology at Nvidia, remarked, "Delivering commercial fusion implies that we can solve intricate challenges through simulation. The synergy between Siemens' tools and Nvidia’s AI will significantly boost CFS’ engineering process."
On the other hand, Siemens is contributing to this revolution by improving the manufacturing processes at CFS’s magnet factory located in Devens, Massachusetts. By utilizing the Siemens Xcelerator alongside Nvidia’s advanced AI visualization capabilities, Siemens’ team is demonstrating how end-to-end digital workflows can transform major industrial processes. Del Costy, president and managing director of Siemens Digital Industries Software in the Americas, emphasized the profound impact of this integration, stating, "When you compile real manufacturing intelligence and apply AI across various scenarios, you eliminate uncertainty and foster innovation. This approach is the future of industrial engineering."
The overarching goal of these collaborative efforts is clear: to make fusion energy not just a distant dream, but a tangible reality for future generations. With CFS’s SPARC project poised to generate net energy, the implications of successfully completing this initiative are monumental – paving the way for unlimited carbon-free energy sources.
As CFS embarks on this ambitious journey, the spotlight will soon shine on their achievements during the upcoming CES 2026 event in Las Vegas, where they are anticipated to unveil a visual illustration of the digital twin. This development exemplifies not just a leap forward in technology, but a collaborative commitment to advancing clean energy solutions in an increasingly resource-hungry world. Ultimately, the efforts of Commonwealth Fusion Systems, Siemens, and Nvidia may signify the dawn of a new era in energy production, where the power of the sun can be harnessed to power our world sustainably.
CFS, founded in 2018, has already managed to raise nearly $3 billion in funding for its groundbreaking projects, showcasing significant investor confidence in the future of fusion energy.
