The international effort to build the world’s largest fusion reactor in southern France has entered a critical new phase, with project leaders adopting a revised 2024 baseline that acknowledges years ...

Proxima Fusion, a two-year-old German nuclear fusion startup, has published plans for a working fusion power plant in a peer-reviewed journal, in what is being touted as an important change in the ...

German startup Proxima Fusion — whose team includes engineers from MIT, Google, SpaceX, and McLaren — has unveiled a fusion energy reactor design it believes offers the quickest route to commercially ...

A student’s small bedroom has become a hotspot for nuclear fusion experiments. With no fancy lab or deep-pocketed sponsors, the work is entirely driven by curiosity and grit. Hudhayfa Nazoordeen, a ...

Scientists say the path to commercial fusion power may hinge on better ways to measure the behavior of superheated plasma.

Experiments at San Diego's DIII-D National Fusion Facility have demonstrated that a new plasma configuration could help increase the stability of tokamak fusion reactors and inform future designs.

Fusion power has long been promised as a clean, abundant energy source, but scientists have struggled to harness it effectively. A new approach, however, may finally bring fusion reactors closer to ...

Predicted motions of hundreds of particles in a fusion reactor. The motions predicted with the new method (orange, red) agree very closely with those predicted by Newton's laws (blue, green), but can ...

Type One Energy has successfully passed the first formal design review for its "Infinity Two" stellarator fusion reactor power plant that aims to deliver 350 megawatts of electricity to the grid by ...

Two U.S. companies — Realta Fusion and X-energy — on Monday announced separate agreements with Japanese counterparts on fusion and nuclear energy. Why it matters: The agreements show the eagerness to ...

First Light Fusion has validated tritium breeding in its FLARE reactor, a step toward solving the tritium supply challenge for scalable fusion energy.

For decades, nuclear fusion has held the promise of clean, limitless energy. However, one persistent challenge has slowed progress: the inability to reliably contain the high-energy particles needed ...
