Commonwealth Fusion Systems closed on its latest $84 million in new funding two weeks ago. The U.S. was still very much in the lockdown phase and getting a deal done, especially a multi-million dollar investment in a new technology aiming to make commercial nuclear fusion a reality after decades of hype, was “an interesting thing” in the words of Commonwealth’s chief executive, Bob Mumgaard. It was actually one time when the technical complexity of what Commonwealth Fusion is trying to achieve and the longterm horizon for the company’s first test technology was a benefit instead of an obstacle, Mumgaard said. “We’re in a unique position where it’s still something that’s far enough in the future that any of the recovery models are not going to affect the underlying needs that the world still has a giant climate problem,” he said. Commonwealth Fusion Systems purports to be one solution to that problem. The company is using technology developed at the Massachusetts Institute of Technology to leapfrog the current generation of nuclear fusion reactors currently under development (there are, in fact, several nuclear fusion reactors currently under development) and bring a waste-free energy source to industrial customers within the next ten years. Commonwealth Fusion Systems core innovation was the development of a high power superconducting magnet that could theoretically be used to create the conditions necessary for a sustained fusion reaction. The reactor uses hydrogen isotopes that are kept under conditions of extreme pressure using these superconducting magnets to sustain the reaction and contain the energy that’s generated from the reaction. Designs for reactors require their hydrogen fuel source to be heated to tens of millions of degrees. The design that Commonwealth is pursuing is akin to the massive, multi-decade International Thermonuclear Experimental Reactor (ITER) project that’s currently being completed in France. Begun under the Reagan Administration in the eighties, as a collaboration between the U.S., the Soviet Union, various European nations and Japan. Over the years, membership in the project expanded to include India, South Korea, and China. While the ITER project also expects to flip the switch on its reactor in 2025, the cost has been dramatically higher — totaling well over $14 billion dollars. The project, which began construction in 2013, will also represent a much longer timeframe to completion compared with the schedule that Commonwealth has set for itself. Picture taken on January 17, 2013 in Saint-Paul-les-Durance, southern France shows the model of the reactor of the future International Thermonuclear Experimental Reactor (ITER) . The International Thermonuclear Experimental Reactor (Iter), based at the French Atomic Energy Commission (CEA) research center of Cadarache in Saint-Paul-lès-Durance, was set up by the EU, which has a 45 percent share, China, India, South Korea, Japan, Russia and the US to research a clean and limitless alternative to dwindling fossil fuel reserves.
