Proponents of inertial fusion energy celebrated in December 2022, when researchers at the National Ignition Facility at Lawrence Livermore National Laboratory achieved fusion ignition by subjecting a carefully crafted diamond cryogenic sphere containing frozen deuterium-tritium fuel to NIF’s laser energy. NIF has yet to repeat the feat, in part because that facility was not designed to produce fusion energy, and ignition requires near-perfect targets. For inertial fusion energy to serve as a reliable power source, it will require swift, reliable, and economic target production.

The Department of Energy announced awards for 18 Innovation Network for Fusion Energy (INFUSE) projects on July 6 that link private fusion energy developers with DOE national laboratories (and, in a first for the program, with U.S. universities) to overcome scientific and technological challenges in fusion energy development. The 18 selected projects include representation from 10 private companies, three national labs, and eight universities.
