The Department of Energy (DOE) today awarded $2.1 million across 9 collaborative projects between DOE national laboratories and private industry aimed at overcoming challenges in fusion energy development. Fusion energy research seeks to harness the energy that powers the sun and stars as a clean, safe, and abundant source of energy on earth.

Today’s awards are part of the Innovation Network for Fusion Energy (INFUSE) program which was established in 2019 by DOE’s Office of Fusion Energy Sciences (FES) and seeks to accelerate fusion energy development through public-private research partnerships.

“After two successful years of INFUSE, it is clear that the program offers significant benefit to the fusion community,” said James Van Dam, DOE Associate Director for Fusion Energy Sciences. “This new round of funding shows continued interest in the program as new companies continue to apply, looking to leverage the unique expertise and capabilities available at the DOE national laboratory system.”

The funding will provide selected companies with access to the world class expertise and facilities of DOE’s national laboratories, which will equip researchers to address the critical scientific and technological challenges of pursuing fusion energy systems. The INFUSE program selected projects from members of the fusion industry for one- or two-year awards between $50,000 and $500,000 each, with a 20% cost share for industry partners. The awards are subject to a successful negotiation of a Cooperative Research and Development Agreement between the companies and the partnering DOE National Laboratories.

“Through partnerships with innovators in private industry, these INFUSE projects will accelerate the development of cost-effective fusion energy technologies,” said Dennis Youchison, director of the INFUSE program and a fusion engineer at DOE’s Oak Ridge National Laboratory.  “Many projects are focused on the near-term technologies needed for accelerated fusion reactor development to supplement carbon-free electricity production and combat global climate change.”

The 9 selected projects include representation from 7 private companies, including new participants General Atomics, Microsoft, and Air Squared. Projects will take advantage of INFUSE’s primary areas of focus: enabling fusion technologies; materials; diagnostics; modeling and simulation; and experimental capabilities.
