General Fusion Hits 1 keV Plasma Milestone with UKAEA Collaboration…

Event summary

General Fusion achieved electron temperatures exceeding 1 keV (12.6 million degrees Celsius) using its Magnetized Target Fusion (MTF) approach in the LM26 demonstration.
The result was co-published with UKAEA and measured using Thomson scattering methods.
General Fusion aims to reach the Lawson criterion and operate a first-of-a-kind fusion plant around 2035.
UKAEA's expertise in plasma diagnostics was critical to measuring plasma conditions in LM26.
Upgrades to LM26 are underway to support higher plasma compression ratios ahead of the next 10 keV milestone.

The big picture

General Fusion's achievement marks a significant step in the race to commercialize fusion energy, a sector where multiple approaches are competing to deliver clean, baseload power. The collaboration with UKAEA highlights the importance of public-private partnerships in advancing fusion technology, as nations and companies worldwide seek to bring fusion power to the grid amid surging electricity demand. The success of General Fusion's MTF approach could reshape the competitive landscape, particularly if it can avoid the need for superconducting magnets and high-powered lasers.
