Sumitomo Corporation’s Yohei Nishitsuji of the Energy Innovation Initiative discusses how a focus on fusion’s “derivative technologies” can support Sumitomo’s vision of fusion power.
The UKAEA and Italian multinational energy company Eni have formed Rh3ova (pronounced Reeova) to offer services to the fusion energy sector including projects related to the use of tritium as a fuel.
The result marks a major engineering milestone for China’s fusion roadmap, supporting future devices such as BEST and CFETR.
Deutsche Welle writes about companies around the world are competing to see who can build the first commercially viable fusion machine, highlighting German startups in the race, supported by major corporations and private investors.
US-based private fusion company Commonwealth Fusion Systems (CFS) becomes the first international partner in the UKAEA’s Lithium Breeding Tritium Innovation (Librti) programme.
Magnetic confinement: Plasma is heated to 100 million °C or more, then squeezed and held in place by strong magnetic fields, allowing many fusion reactions to occur. (Example: tokamaks, stellarators)
Inertial confinement: Tiny fuel pellets are struck by powerful lasers. The outer layer explodes outward, compressing the core to fusion conditions for a few nanoseconds, producing a brief but intense pulse of energy from each pellet. (Example: National Ignition Facility)
Hybrid systems: Combine compression (e.g., from lasers, plasma pistons, or mechanical impact) with moderate magnetic fields to reduce energy losses and improve confinement.
Electrostatic fusion: Uses high electric potentials to accelerate ions toward a central reaction zone, causing them to collide at high energies and fuse. The ions are guided and confined by electric fields rather than magnets, creating a compact environment for fusion reactions.
