Devens, MA, USA
Hybrid position requiring in-office presence.
Commonwealth Fusion Systems focuses on developing fusion energy as a sustainable and abundant power source to address climate change. The company utilizes advanced magnet technology, created in partnership with MIT, to build smaller and more cost-effective fusion systems called tokamaks. These devices use magnetic fields to confine plasma, making them efficient for achieving fusion. Currently, CFS is manufacturing high-temperature superconducting magnets and constructing SPARC, the first commercially-relevant net energy fusion machine, which will lead to the development of ARC, the first fusion power plant. CFS aims to provide cost-competitive clean fusion energy, generating revenue through the sale of these systems. The company is distinguished by its mission-driven team and commitment to scientific integrity, fostering an environment that encourages the best ideas to emerge.

Commonwealth Fusion Systems has reportedly raised $1 billion in an extension of its Series B round to support the buildout of its demonstration fusion power reactor... University of Wisconsin spinout Realta raised $36 million for its modular magnetic mirror fusion technology.
Commonwealth Fusion Systems (CFS) has raised over $1 billion, led by an unnamed hyperscale data center developer, to build 400MW fusion reactors within a decade. CFS plans to construct the 'ARC' fusion power plant in Virginia by the early 2030s and aims to have a test system, 'SPARC,' by 2027. Despite challenges in fusion investments, CFS secured funding, while other companies like First Light Fusion and General Fusion face financial difficulties.
CFS has been developing SPARC step by step for years.
Fusion Fuel EfficiencyNuclear Fusion is potentially the ultimate green energy source, producing no dangerous byproducts, radioactivity (the only “waste” is helium), or greenhouse gases. And it could be powered by a fuel so abundant that it is a significant percentage of the entire Universe: deuterium, an isotope of hydrogen.But this is also a very difficult to achieve form of energy generation. It requires replicating on Earth the conditions in the core of the Sun, with tremendous pressures and tens or hundreds of millions of degrees.Nuclear fusion has been achieved in physics laboratories for decades, but a net energy-positive fusion reaction is still to be reached. This is what many are racing to accomplish, from the international megaproject ITER to commercial fusion projects like Commonwealth Fusion Systems and Proxima Fusion.Commercial viability will depend not only on achieving stable and energy-positive plasma generation, but also on the general efficiency of the process.One open question is the fuel efficiency. Deuterium is known to be partially absorbed by the walls of the tokamak fusion reactors. Researchers at Princeton University, University of California, University of Tennessee, Sandia National Laboratory, and General Atomics are figuring it out.They published their results in Nuclear Materials and Energy1, under the title “Deuterium retention behaviors of boronization films at DIII-D divertor surface”.Deuterium, Tritium FusionThe lighter an atom is, the more potential energy is released when it undergoes nuclear fusion
