At CES 2026, fusion startup CFS unveiled plans to build a virtual replica known as a digital twin of its fusion reactor, Sparc, using NVIDIA’s AI and simulation technologies along with Siemens’ engineering and data tools. 
This digital twin lets engineers run simulations, test ideas, and compare results with real experiments in a virtual setting, dramatically speeding up the research cycle. 
According to CFS leadership, this approach could compress years of manual experimentation into just weeks of virtual optimization, helping accelerate fusion development toward commercial energy. 
NVIDIA announced last August that it is an investor when they joined a $863 million series B2 round which has raised billions for CFS to pursue commercial fusion power as a potentially transformative clean energy source.
