Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.

Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

California-based Pacific Fusion, in partnership with Sandia National Laboratories, has reported “removing a significant roadblock to practical fusion power at scale” by achieving pulser-driven inertial confinement fusion (ICF) with a simpler, less expensive approach than previously used.

Granholm

Secretary of energy Jennifer Granholm recently discussed the future of clean energy with Christopher M. Matthews, the U.S. energy editor for the Wall Street Journal. The May 15 live Q&A focused on Granholm’s perspective on the Biden administration’s policies for decarbonization and energy security. Granholm, who mentioned nuclear briefly at beginning of her remarks, returned to the issue at the end of the half-hour interview. In her answer to Matthews’s question, she addressed nuclear industry incentives, safety and waste concerns, next-generation technologies, and fusion.

Fossil fuels? Matthews opened the discussion by noting President Biden’s signing of the Inflation Reduction Act (IRA) last year, allocating “billions of dollars in tax credits and federal loans to boost green energy, including electric vehicles, hydrogen production, and more.” He added, “At the same time, the administration has called on oil and gas producers to increase drilling to slow inflation and to tamp down energy prices.”

Physicist Andrea “Annie” Kritcher’s dedication to fusion target design has earned her a spot on the TIME100 Most Influential People list for 2023. Today, Kritcher and 99 other individuals on that list—among them Elon Musk, King Charles, Judy Blume, Patrick Mahomes, Beyoncé, Lionel Messi, Janet Yellen, and MrBeast—are being honored at the TIME100 Summit and Gala at the Lincoln Center in New York City.

Nuclear fusion “might actually be on the cusp of commercial viability” today, says a recent article in Fortune magazine. The article offers a brief review of recent technical and entrepreneurial developments in fusion energy. It also places these developments in perspective regarding the hurdles that remain before commercialization can be realized.

Lawrence Livermore National Laboratory is celebrating the yield from an experiment at the National Ignition Facility (NIF) of more than 1.3 megajoules of energy—eight times more than the yield from experiments conducted this spring and 25 times more than NIF’s 2018 record yield.
