Eight companies were chosen to develop fusion pilot plant designs through the Department of Energy’s Milestone-Based Fusion Development Program just over two years ago. It wasn’t until June 2024 that the DOE announced that protracted negotiations over program metrics had been concluded. Now, two years on, the original eight are “making great progress,” according to Colleen Nehl, program manager for public-private partnerships in the DOE’s Office of Fusion Energy Sciences (FES). Nehl spoke during a June 4 webinar convened on short notice to discuss the latest fusion Milestone news: a fast-tracked opportunity for additional teams to access remaining Fiscal Year 2025 funding for the Milestone program.

The Department of Energy announced six Fusion Innovative Research Engine (FIRE) collaboratives set to receive funding of $107 million on January 16.

Hours before the Senate Committee on Environment and Natural Resources (ENR) opened a scheduled September 19 hearing on fusion energy technology development, CNN published an article titled “The US led on nuclear fusion for decades. Now China is in a position to win the race.” The article was entered into the hearing record, but senators had already gotten the message.

Just one week after the White House Office of Science and Technology Policy hosted a summit on domestic nuclear deployment, they filled a room again on June 6 for a livestreamed event cohosted with the Department of Energy to announce a new DOE fusion energy strategy and new public-private partnership programs, and to hear directly from stakeholders—including scientists, private fusion companies, investors, and end users—during panel discussions on fusion science and technology progress and the path to fusion energy commercialization.

The Office of Fusion Energy Sciences (FES) in the Department of Energy’s Office of Science introduced a new plan—"Building Bridges: A Vision for the Office of Fusion Energy Sciences”—during a Fusion Energy Sciences Advisory Committee (FESAC) hearing on December 13, and announced that news December 14. What’s included? A plan for the DOE to “establish the steps needed to help advance fusion energy, including addressing key science and technology gaps in the supply chain and industry.” The vision is less a guiding document than a preview of DOE-FES’s near-term intentions, which include drafting a fusion science and technology road map in 2024 to shape investments for the coming decade.

The Department of Energy recently announced that it was establishing three inertial fusion energy (IFE) hubs and funding them with a total of $42 million over four years. The leaders of the three hubs selected by competitive peer review—Colorado State University, Lawrence Livermore National Laboratory, and the University of Rochester—all issued press releases touting the attributes and plans of their facilities and their research collaborators on the same day—December 7.

The Department of Energy is providing $4.6 million in funding for 18 projects at national laboratories and U.S. universities to help address critical scientific and technological challenges in pursuing fusion energy systems.

From a crowded field of would-be fusioneers, the Department of Energy has selected eight companies for the public-private Milestone-Based Fusion Development Program to develop fusion pilot plant designs and resolve related scientific and technological challenges within five to 10 years. The DOE announced awards totaling $46 million for an initial 18 months of work on May 31.

Lawrence Livermore National Laboratory hosted current and former staff, government officials, and media on May 8 to celebrate the lab’s achievement of fusion ignition at the National Ignition Facility (NIF) on December 5, 2022. Energy secretary Jennifer Granholm and undersecretary for nuclear security and National Nuclear Security Administration administrator Jill Hruby were in attendance, and Granholm took the opportunity to announce funding of up to $45 million to support inertial fusion energy (IFE) research and development. The Department of Energy’s Office of Science (DOE-SC) wants to establish multiple IFE Science and Technology Innovation Hubs (IFE S&T hubs), with total funding for 2023 of up to $9 million for projects lasting up to four years in duration.

The Department of Energy’s Office of Science published a notice in the March 27 Federal Register calling for input on technological approaches to a Fusion Prototypic Neutron Source (FPNS) for materials irradiation research under DOE-SC’s Fusion Energy Sciences program, as well as partnership models that could accelerate the construction and delivery of the facility. The request for information (RFI) calls for responses by May 11.

The Department of Energy’s Office of Science announced $2.3 million in funding on January 17 for 10 fusion energy projects that will allow private companies to work with national laboratories to address specific challenges in fusion energy development. Seven private companies and seven national laboratories are represented in the 10 projects selected for funding, provided through the INFUSE (Innovation Network for Fusion Energy) program. The second-round fiscal year 2022 awards follow a first round of 18 project awards announced in July 2022.

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.

The White House Office of Science and Technology Policy and the Department of Energy cohosted the White House Summit on Developing a Bold Decadal Vision for Commercial Fusion Energy on March 17. The livestreamed event brought together fusion leaders from government, industry, academia, and other stakeholder groups to showcase recent achievements in fusion research and discuss the administration’s strategy to support the development of commercial fusion energy. Energy Secretary Jennifer Granholm’s announcement of a new agency-wide fusion energy initiative and a funding opportunity worth $50 million for magnetic confinement fusion research made March 17 a lucky day indeed for the U.S. fusion energy community.

The Department of Energy’s Office of Science (DOE-SC) and the National Nuclear Security Administration (NNSA) on July 27 announced $9.35 million for 21 research projects in high-energy-density laboratory plasmas.
