Antares Nuclear Inc.’s Mark-0—a sodium heat-pipe-cooled microreactor fueled by high-assay low-enriched uranium (HALEU) tri-structural isotropic (TRISO) fuel compacts—has achieved zero-power criticality at Idaho National Laboratory’s (INL’s) Reactor and Critical Experiment (RACE) facility, becoming the first advanced reactor to reach that milestone under the Department of Energy’s (DOE’s) Reactor Pilot Program. The development, announced on June […]

Commonwealth Fusion Systems (CFS) announced the company has published five peer-reviewed physics basis papers detailing its work on the group’s ARC fusion power plant.

Google and Intersect, a clean energy developer Google acquired in March 2026, have launched construction on the Meitner Energy Center, a co-located data center and generation complex in the Texas Panhandle that will integrate more than 1 GW of wind, solar, and battery storage with on-site gas-fired generation for reliability firming. The project is located […]

Fusion energy group Helion said the company has completed a $465-million Series G investment round, increasing the Everett, Washington-based group’s valuation to $15.5 billion. Helion is among dozens of U.S. and global companies working to commercialize fusion power.

Artificial intelligence (AI) is transforming the energy system: While the expansion of wind and solar power continues to progress across Europe, AI will ensure the efficient use of every generated kilowatt-hour. Intelligent algorithms that synchronize generation and consumption in real time will help stabilize grids, avoiding expensive curtailment. Software will become an important tool for […]

Urenco USA, operator of the only U.S. commercial-scale uranium enrichment facility, will expand low-enriched uranium (LEU) capacity at its National Enrichment Facility (NEF) in Eunice, New Mexico, by nearly 50% through a privately funded, multibillion-dollar investment that includes construction of a new enrichment plant. The project will add 2.1 million separative work units (SWU) of […]

Colorado-headquartered Xcimer Energy has announced the start of operations for Phoenix, what the company calls the largest privately owned laser system in the world. Phoenix, named after the legendary bird from Greek and Egyptian mythology, is the company’s prototype for commercializing laser fusion.

The Trump administration’s unprecedented assault on wind energy development in the U.S. stands in sharp contrast to its promotion of oil and gas, liquefied natural gas (LNG) production, and microreactor nuclear projects. Agencies have blocked 165 wind projects nationwide while simultaneously spending nearly $2 billion in taxpayer funds to convince energy companies to abandon offshore […]

Another U.S.-based energy company said its technology has achieved key performance metrics that advance its goal of commercial fusion by the mid 2030s. California-headquartered Pacific Fusion on June 2 said its core pulsed power technology is on track to achieve net facility gain by 2030. That’s the state where the “entire fusion machine produces more […]

According to the State of the Global Climate 2024 report released by the World Meteorological Organization (WMO), the continued rise in global temperatures is driving a measurable increase in both the frequency and intensity of extreme weather events. Among these, tropical cyclones, including hurricanes and typhoons, as well as extreme precipitation events, have emerged as […]
