Is Clean, Green Fusion Power In Our Near Future?


Fusion is the energy source of the future—and it always will be. That used to be a Unix joke, but in various forms Unix has actually become pretty widespread these days. It runs the server that hosts the web page you’re reading; it’s the underlying guts of Apple’s Mac operating system; and Linux is—well, not really “popular” by any fair definition of the word, but no longer just a fringe OS either.

So maybe fusion is about to break through too:

Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready in a decade.

Tom McGuire, who heads the project, said he and a small team had been working on fusion energy at Lockheed’s secretive Skunk Works for about four years, but were now going public to find potential partners in industry and government for their work.

….Initial work demonstrated the feasibility of building a 100-megawatt reactor measuring seven feet by 10 feet….Lockheed said it had shown it could complete a design, build and test it in as little as a year, which should produce an operational reactor in 10 years, McGuire said.

Over at Climate Progress, Jeff Spross is containing his enthusiasm:

At this point, keeping the world under 2°C of global warming will require global greenhouse gas emissions to peak in 2020 and fall rapidly after that….So by Lockheed Martin’s own timeline, their first operational CFR won’t come online until after the peak deadline. To play any meaningful role in decarbonization — either here in America or abroad — they’d have to go from one operational CFR to mass production on a gargantuan scale effectively overnight. More traditional forms of nuclear power face versions of the same problem.

A WW2-style government mobilization might be able to pull off such a feat in the United States. But if the political will was there for such a move, the practical question is why wait for nuclear? Wind and solar are mature technologies in the here and now — as is energy efficiency, which could supply up to 40 percent of the effort to stay below 2°C all by itself.

Jeez. I get where Spross is coming from, but come on. If Lockheed Martin can actually pull this off, it would mean huge amounts of baseload power using existing grid technology. It would mean cheap power from centralized sites. It would mean not having to replace every building in the world with high-efficiency designs. It would mean not having to install wind farms on millions of acres of land. It would mean not having to spend all our political efforts on forcing people to make do with less energy.

More generally, it would mean gobs of green power at no political cost. That’s huge.

The big question is whether Lockheed Martin can actually pull this off. Lots of people before them have thought they were on the right track, after all. But if they can, it’s a game changer. Given the obvious difficulties of selling a green agenda to the world—and the extreme unlikelihood of making that 2020 deadline with existing technologies—I’ll be rooting for Lockheed Martin to pull this off. Cynicism can be overdone.

Editors’ note: Over on the Blue Marble blog Climate Desk Producer James West spoke with a thermonuclear plasma physicist who doubts the significance of this breakthrough and called Lockheed’s announcement “poppycock.” So there’s that.
