DOE Milestone Program disburses $42M to 8 private fusion developers

The Department of Energy released a second tranche of cost-shared awards under its Milestone-Based Fusion Development Program, disbursing $42 million across eight private developers. The awards are tied to specific technical gates — first plasma, tritium self-sufficiency demonstrations, magnet endurance benchmarks — rather than to time-based milestones.

Commonwealth Fusion, Helion, Tokamak Energy, TAE Technologies, Type One Energy, Realta Fusion, Xcimer Energy, and Focused Energy each received between $3 million and $8 million in this round. DOE Office of Science director Asmeret Asefaw Berhe said the program is designed to derisk first-of-a-kind plant cost estimates, a precondition for private financing of any commercial fusion plant.

Total Phase-II funding through 2029 is expected to exceed $1.2 billion in federal commitments, with industry cost-share more than doubling that figure.
