Commonwealth Fusion Systems aims to complete demonstration reactor with $1B funding round
The latest cash infusion will allow the company to complete its demonstration reactor, SPARC, which CEO Bob Mumgaard said is now “about 80% complete.”
Commonwealth Fusion Systems, a Massachusetts-based company, has raised an additional $1 billion in funding to aid in the construction of its first commercial fusion power plant. The funding, disclosed by CEO and co-founder Bob Mumgaard, includes investments from various institutional investors such as pension funds, sovereign wealth funds, and industrial corporations.
The money will be used to complete the demonstration reactor, named SPARC, and pave the way for the deployment of the company's next-generation reactor, ARC, which will be located in Virginia. Fusion technology has the potential to generate large amounts of power with minimal hazardous radioactive waste, making it an attractive alternative to nuclear fission.
While experts remain divided on the timeline for commercial fusion, Commonwealth Fusion Systems is pushing for a more aggressive timeline. The company has secured permits and signed offtake agreements with Google and ENI for its commercial reactor, and it expects to show net energy gain in 2027. Dominion Energy has provided non-financial collaboration for the project and has expressed confidence in the technology's potential to meet growing demand for low-carbon, firm power.
