Join us August 12 for Fusion 2035: The 10-Year Shot Clock, a half-day webinar featuring leaders from across the fusion ecosystem.
Things You Gotta Know
China’s $2B Fusion Investment Puts U.S. on the Back Foot
China has committed $2.1 billion to centralize and accelerate its national fusion program, forming China Fusion Energy Co. as a state-directed fusion commercialization effort. Backed by university researchers, industrial giants, and state-owned energy firms, the initiative mirrors the private-sector approach taken by U.S.-based Commonwealth Fusion Systems, down to the use of high-temperature superconducting magnets to power compact tokamak reactors. Yet unlike the U.S., China's strategy is coordinated and capitalized at scale, establishing visible infrastructure and consolidating expertise. While the U.S. has pioneered key fusion technologies, its federal commitment remains modest, with only a fraction of Department of Energy funds directed toward commercialization. As China ramps up a full-fledged industrial policy around fusion, U.S. leadership risks ceding the future of global energy dominance unless policymakers dramatically scale up investment and infrastructure.
Realta Fusion Predicts Commercial Energy Gain Using Magnetic Mirror Design
Realta Fusion has released new modeling that shows its magnetic mirror design, which can exceed energy gain thresholds needed for commercial power generation. The company’s latest results suggest a 50-meter center cell could yield a Q value above 5, with longer configurations breaking into double digits. At the heart of the challenge lies the DCLC instability, a plasma behavior that once plagued magnetic mirror concepts. Realta’s second paper tackles this directly, offering new insights for containment. These findings position Realta’s mirror-based system as a potentially simpler, more compact alternative to tokamaks, with fewer moving parts and scalable geometry. The company has now passed a key technical milestone, attracting attention in a market dominated by spherical and laser-based contenders.
China’s Fusion-Grade Super Steel Sets New Standard in Reactor Construction
After more than a decade of quiet iteration, China’s materials scientists have delivered CHSN0, a cryogenic-grade super steel designed to endure magnetic fields twice as strong as ITER’s and brute mechanical stress nearing 1,300 MPa. The alloy, now in active use on the country’s BEST fusion reactor, emerged from a national push that began in 2011 and accelerated under the guidance of physicist Zhao Zhongxian. The breakthrough came from subtle shifts in vanadium, carbon, and nitrogen levels. While Western experts once dismissed China’s effort as unnecessary — claiming 316LN stainless steel had no peer — CHSN01 now stands as proof that the Chinese fusion program is betting on a reactor built to generate power, not just science.
Dual Ion Beam Testing Exposes Limits of Advanced RAFM Fusion Steels
A University of Michigan-led study has revealed that castable nanostructured alloy #9 (CNA9), a next-gen RAFM steel, may not withstand the extreme conditions expected inside fusion reactors. Though its titanium-carbide nanoprecipitates initially trapped helium effectively, they dissolved under high radiation doses, leading to material swelling. Using dual ion beams to replicate fusion-relevant damage and helium exposure, researchers demonstrated that CNA9's structural integrity falters at radiation levels above 15 dpa. The findings underscore a need to redesign RAFM alloys for greater resilience, with denser and more stable TiC networks that can survive fusion’s punishing environment.
Interview with Realta Fusion: Making Tandem Magnetic Mirrors Work for Fusion Energy
Realta Fusion VP of R&D Derek Sutherland breaks down how tandem magnetic mirrors and recent modeling advances show Q>10 is achievable, setting the stage for a FOAK fusion plant in the early 2030s. With a focus on simplicity, scalability, and direct energy conversion, Realta is carving its own path in the fusion race.
The Race to the World’s First Fusion Power Plant: Who is Really Going to Win the Race?
Helion Energy has started construction of its Orion fusion plant in Washington, aiming to supply power to Microsoft by 2028. But what does being the “first” fusion power plant truly mean? We explore Helion’s challenges, how it stacks up against the Commonwealth Fusion Systems ARC project, and why the race to commercial fusion matters for global clean energy growth.
