Microsoft agrees to buy power from Sam Altman-backed Helion in 2028

Microsoft said Wednesday it has signed a power purchase agreement with nuclear fusion startup Helion Energy to buy electricity from it in 2028.

The deal is a notable vote of confidence for fusion, which is the way the sun makes power and holds promise of being able to generate nearly unlimited clean power, if it can be harnessed and commercialized on earth. For decades, fusion been lauded as the holy grail of clean energy — tantalizing because it’s limitless and clean, but always just out of reach.

As responding to climate change has become an increasingly urgent goal for companies and countries around the globe, investors have poured $5 billion into private fusion companies looking to turn that holy grail into electrons flowing through wires.

Microsoft’s agreement to buy electricity from Helion is the first time a fusion company has inked a deal to sell electricity, according to Andrew Holland, the CEO of the Fusion Industry Association.

“This is the first time that I know of that a company has a power purchase agreement signed,” Holland told CNBC. “No one has delivered electricity, and Helion’s goal of 2028 is aggressive, but they have a strong plan for how to get there.”

Helion was founded in 2013 and currently has about 150 employees, with headquarters in Everett, Wash. One of the early and most significant investors in Helion, Sam Altman, is also a founder of OpenAI, the artificial intelligence organization that developed the chat platform ChatGPT, in which Microsoft has invested many billions of dollars. Altman believes the two deals are equally important and correlated components of the future he sees for humanity.

“My vision of the future and why I love these two companies is that if we can drive the cost intelligence and the cost of energy way, way down, the quality of life for all of us will increase incredibly,” Altman told CNBC. “If we can make AI systems more and more powerful for less and less money — same thing we are trying to do with energy at Helion — I view these two projects as spiritually very aligned.”

If demand for and use of artificial intelligence continues to increase, then that will increase demand for energy, too.

The potential of fusion is “unbelievably huge,” Altman told CNBC. “If we can get this to work — if we can really deliver on the dream of abundant, cheap, safe, clean energy that will transform society. It’s why I’ve been so passionate about this project for so long.”

In 2021, Altman told CNBC he put $375 million into Helion. As of Tuesday, this is still his largest investment ever, Altman told CNBC. In total, Helion has raised raised $577 million.
