Top developments
India commissions 400 kW gyrotron for SST-1 tokamak
On September 14, 2026, India successfully installed and commissioned a new 82.6 GHz, 400 kW gyrotron on the SST-1 tokamak in Gujarat. This upgrade is critical for sustaining ultra-hot plasma for longer durations, strengthening India's capability to conduct advanced fusion research experiments. The move signals India's intent to accelerate its timeline for experimental fusion power generation.
Shanghai startups race toward Q>1 by 2030
Local media reports that Shanghai-based fusion enterprises are collectively targeting the achievement of a fusion gain factor (Q) greater than 1 between 2029 and 2030. Several small-to-medium-sized devices using innovative technology routes are scheduled for construction and debugging in the next two to three years. This aggressive timeline positions Shanghai as a competitive hub alongside Hefei, challenging the traditional dominance of state-led projects like EAST and BEST.
Fusion startups pivot to defense partnerships
TechCrunch reported on September 13, 2026, that fusion energy startups are increasingly securing deals with the defense sector. These partnerships reignite historical ties between fusion research and national security, providing new funding streams and potential first-of-a-kind application markets beyond the electrical grid. This shift may influence how private capital evaluates risk and return in the sector.

China: Industry forum highlights plasma heating bottlenecks
In Hefei, the "Controlable Nuclear Fusion Plasma Heating Technology Industry Forum" held on September 15, 2026, brought together researchers, industry players, and investors. Experts emphasized that while scientific feasibility is proven, engineering challenges remain in heating plasma to hundreds of millions of degrees. The forum underscored the growing collaboration between Chinese research institutions and private capital to overcome these auxiliary heating hurdles.
Context & numbers
- SST-1 Gyrotron Specs: The newly installed gyrotron in India operates at 82.6 GHz with a power output of 400 kW.
- Shanghai Timeline: Multiple Shanghai startups have publicly stated targets of achieving Q>1 by 2029–2030.
- Defense Sector Interest: New defense-related deals were announced or reported for fusion startups as of mid-September 2026.
On the radar
- ITER Council Meeting: The ITER Council is expected to review a proposal with "sufficient detail" for an updated project baseline at its next meeting in November 2026. This baseline will define the schedule for nuclear (deuterium-tritium) operation.
- KSTAR Tungsten Upgrade: While recent news from late August confirmed the start of joint K-EU research on tungsten environments, monitoring continues for the completion of KSTAR's internal component upgrades which are critical for long-pulse plasma operations.
