Fusion Remains Energy's Elusive Holy Grail --- Tech company sees breakthrough ahead, but hasn't published the evidence of it

“Many experts consider fusion the holy grail of energy that could deliver enormous power in the distant future. President Trump's media company is betting it is imminent.

 

Trump Media & Technology's planned merger with fusion company TAE Technologies would bring fusion investing -- usually the realm of high-risk-tolerant venture investors -- to the public markets for the first time. It is a gamble that fusion power, which no company or researcher has yet delivered, can be built in time to meet the artificial-intelligence boom's growing power requirements.

 

There is still a lot to prove.

 

Fusion powers the sun and could produce almost limitless amounts of carbon-free energy if it can be harnessed on Earth. There are so many hurdles that the joke in the energy industry is that fusion is 10 years away and always will be.

 

"The challenge is still: Can we make the science and technology work?" said George Tynan, adjunct professor in the Massachusetts Institute of Technology's nuclear science and engineering department.

 

There has been growing enthusiasm for fusion, especially following a 2022 breakthrough at Lawrence Livermore National Laboratory in Livermore, Calif., in which researchers were able to create a fusion reaction that produced more energy than it consumed.

 

Net gain isn't the same as producing net power, though.

 

"That's not a power reactor," Tynan said. "You then have to solve a bunch of engineering problems to turn that from, like, a demonstration into something that might be commercially viable."

 

There are now dozens of fusion companies globally -- and a race to see who can achieve commercial fusion first. China thus far has been outspending the U.S. The Fusion Industry Association has tracked $9.7 billion in investments into private companies, the bulk of them coming in the past couple of years and largely in the U.S.

 

TAE is one of the oldest fusion companies, founded in 1998, and has raised more than $1.3 billion. It is backed by companies such as Alphabet and Chevron Technology Ventures.

 

Michl Binderbauer, chief executive of TAE, said in an interview that the advances in the company's research and latest reactor have led to a "really massive move forward on the science and technology front."

 

TAE's next reactor design will be smaller and higher performance, which means that capital has become the big challenge for moving fusion power forward, rather than technology, he added.

 

Trump Media will provide $200 million in cash to TAE at the deal's signing and $100 million with the filing of the registration statement with the Securities and Exchange Commission.

 

The companies said Thursday when announcing their tie-up that they intend to begin construction next year on a 50-megawatt utility-scale fusion power plant and hope to generate first power in 2031.

 

"With that new machine, we should reach with well within striking distance" of generating power, Binderbauer said. "We have data that makes us very highly confident that the next step is within our reach in this mission."

 

The industry is waiting for specifics about TAE's breakthrough.

 

Adam Stein, director for nuclear energy innovation at the Breakthrough Institute, said he is surprised that the company hasn't yet published scientific evidence of a breakthrough, if it is in fact ready to launch a utility-scale project.

 

"That's what I would have expected to see from a company that achieved what they thought was going to be the next leap in fusion outcomes, not an announcement of a partnership," he said.

 

Binderbauer said the company has and will continue to publish academic papers on its work.

 

"We open up to scrutiny and we're going to continue to do that," he said.

 

Nuclear fusion occurs when two light atomic nuclei merge to form a single heavier one. That process releases huge amounts of energy, no carbon emissions and limited radioactivity.

 

Fusion reactions take place in a state of matter called plasma -- a hot charged gas made of ions and free-moving electrons -- and require temperatures exceeding 100 million degrees Celsius to enable the nuclei to overcome their mutual electric repulsion and collide.

 

The International Atomic Energy Agency projects that the first small-scale fusion pilot plants will begin producing electricity for testing and demonstration in the 2030s. The U.S. Department of Energy is aiming for fusion power in the 2030s.” [1]
