Fusion power industry leader Commonwealth Fusion Systems is building its first demonstration plant utilizing the same process that fuels the sun, and now it’s partnering with Siemens and Nvidia to use AI to eventually help power the AI boom.
Essentially marking the debut of fusion power at CES 2026 in Las Vegas, Commonwealth CEO Bob Mumgaard joined Siemens CEO Roland Busch during his Jan. 6 keynote to tout their teamwork and the ambitious plans for consistent, clean power without radioactive waste, intermittency issues, or the dependence on foreign supply chains.
“AI factories and data centers require gigawatts of electric power,” Busch said on stage. “What if we had an energy source that was clean, safe, affordable, and practically limitless?”
Backed by Nvidia, Google, Mitsubishi, Bill Gates, and more, Commonwealth Fusion Systems (CFS) leads the nascent fusion sector in funding, contracts, and has the advantage of being founded earlier than most in 2018 through a spinoff from the Massachusetts Institute of Technology.
“Fusion is no longer a science project; it’s actually the next big thing in tech,” Mumgaard said.
