Microsoft signs power purchase  agreement with nuclear fusion company

eBusiness Weekly

Microsoft said on 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 commercialised on earth. For decades, fusion been lauded as the holy grail of clean energy — tantalising 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 US$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 said. “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 said. “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 tsaid. “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 said he put US$375 million into Helion. As of Tuesday, this is still his largest investment ever, Altman said In total, Helion has raised raised $577 million.

Why Helion is announcing a 2028 goal now

As part of the power purchase agreement, Helion is expected to have its fusion generation device online by 2028 and to reach its target power generation of 50 megawatts or more within an agreed-upon one-year ramp up period. When the fusion device is fully up to speed producing 50 megawatts of energy, it will be able to power the equivalent of approximately 40,000 homes in Washington state.

While Helion’s deal with Microsoft is to get 50 megawatts online, the company eventually aims to produce a gigawatt of electricity, which is one billion watts, or 20 times the 50 megawatts it is selling to Microsoft. Microsoft will pay for the megawatt hours of electricity as Helion delivers them to the grid.

“This is a real PPA, so there’s financial penalties if Helion can’t deliver power. So we’ve really put our skin in the game on this too — that we believe we can deliver this power and are committed to it with our own financial incentives,” David Kirtley, CEO at Helion, told CNBC.

Altman advocated for the two companies to work together, he said, but the deal is the result of work Helion has done independently. “It was not my doing,” he said.

Microsoft and Helion have been working together for years, Kirtley said. “The first visit we had from the Microsoft team was probably three of our prototypes ago, so many years ago. And then we’ve been working very closely with their data center technology team here in Redmond,” Kirtley said.

After all, Microsoft needs power and has aggressive climate goals. Microsoft has a goal to have 100 percent of its electricity consumption, 100 percent of the time, matched by zero-carbon energy purchases by 2030.

Carbon-free energy includes hydro, nuclear and renewables for Microsoft, a Microsoft spokesperson said.“We are optimistic that fusion energy can be an important technology to help the world transition to clean energy,” Brad Smith, president at Microsoft, said in a written statement.

“Helion’s announcement supports our own long term clean energy goals and will advance the market to establish a new, efficient method for bringing more clean energy to the grid, faster.”

For Helion to be able to deliver electricity generated by fusion to customers requires years of advance planning on the transmission and regulatory fronts.

In that way, announcing a contract now to sell electricity in 2028 gives Helion time to plan and to pick a location in Washington State to put this new fusion device.

“One reason we’re doing the announcement today is that so we can be working with the communities involved, we can be working with regulators, and the power utility on citing this right now,” Kirtley said. “Even five years is a short amount of time to be hooked up to the grid. And we want to make sure that we can do that.”

Indeed, the transmission system in the United States, meaning the series of wires that carry electricity from where it is generated to where it is used, is largely tapped out. Getting new power generation connected to the grid can take years. Helion is working with Constellation to secure its transmission needs.

‘We’re not here to build systems in a lab’

The best-known pathway to commercializing fusion is with a donut-shaped device called a tokamak.

The international fusion project under construction in Southern France called ITER is building a tokamak, and Commonwealth Fusion Systems, a fusion start-up spun out of MIT which has raised more than $2 billion in funding, is using tokamak technology. For comparison, CFS plans to have its first power plant on the grid and selling electricity in the early 2030s.

Helion is not building a tokamak. It is building a long narrow device called a Field Reversed Configuration.

Broadly speaking, Helion’s approach involves shooting plasma (the fourth state of matter after solid, liquid and gas) from both ends of the device at a velocity greater than one million miles per hour. The two streams smash into each other, creating a superhot dense plasma, where fusion occurs. — CNBC
