FEI Monthly Roundup - November 2025

Welcome to our round-up of what’s been happening in fusion and within Fusion Energy Insights over the past month.
3 Top Fusion News Stories
DOE Creates New Fusion Office as Part of Major Reorganisation
The US Department of Energy (DOE) has created a standalone Office of Fusion Energy, elevating fusion to the same organisational level as the Office of Science. DOE announced the change as part of a wider restructuring. The new office consolidates fusion activities that previously sat within the Office of Science, and reorganises several other energy-related offices.
Zap Energy Ramps Up Plasma Pressure in Fuze-3 Device
US startup Zap Energy has unveiled results from its latest fusion device, Fuze-3, which achieved plasma pressures of over 232,000 psi (1.6 GPa) and temperatures exceeding 21 million °C. (100 million degrees+ is fusion temperatures.) The company’s sheared-flow-stabilised Z-pinch design relies on electrical currents to generate and compress plasma, without the need for external magnetic coils. Zap reached these conditions by modifying its machine design to include a third electrode, allowing two simultaneous power pulses for greater control. The team now plans to commission a new generation of its Fuze device this winter as it continues its march toward energy breakeven.
Tokio Marine and Northcourt launch fusion insurance facility
Tokio Marine GX and specialist underwriter Northcourt, part of the Optio Group, have launched NC Fusion, the first dedicated insurance facility for nuclear fusion technology in the Lloyd’s market. A representative from Tokio Marine GX explained that the insurance sector usually develops new policies after innovations have arrived, so with NC Fusion they are attempting a more proactive approach. The new framework will evolve alongside project maturity, covering all stages from R&D to commercial operation.

After the "First", Fusion Must Fit
This was our industry analysis “Graph of the Month” piece this time.
Every month, our industry experts at Fusion Advisory Services pick an interesting graph from the work that has been going on at FAS—something that gives some insight into significant trends, commercialisation considerations or fusion industry development.
This month, we analysed the upcoming private and public fusion power plant demonstrations by year and projected capacity in GWe. One of these demonstrations will hopefully be the “first” fusion demonstration.
This matters because while the “first” is important, the development of how fusion fits into the world’s energy mix will truly start after this milestone has been achieved. Fusion’s success will depend on its ability to evolve, to serve the shifting needs of industries, economies, grids and nations on the path to net zero.

Past Online Events
13th November: Japanese HTS magnet development and the Helical Fusion stellarator roadmap Insights Q&A
Fusion magnets need to both create the magnetic fields required for fusion reactions and also operate successfully in fusion conditions (where other magnetic fields are present). Japan’s Helical Fusion recently completed a successful performance test of a high-temperature superconducting (HTS) coil under fusion-relevant magnetic conditions—the first such achievement globally. In this Q&A we discussed the recent HTS magnet milestone and implications both for Helical Fusion and the broader fusion industry, and found out about the Japanese “heliotron” stellarator design.

Looking Forward
4th December, 2-3PM: The Role of EPCs in Fusion Commercialisation (A Technical Discovery Session)
This session brings you insights into EPCs:
- how Engineering, Procurement, Construction companies (EPCs) can engage with fusion developers during design, procurement and delivery,
- the contracting and regulatory models emerging from early demonstration projects,
- the barriers to industrial-scale rollout,
All highlighting how EPC expertise can help move fusion from prototype to infrastructure.
Speakers from three different companies:
- Lee Patrick, Fusion Energy Market Lead, from Atkins: an EPC
- Lisa Davies, Project Director & Engineering Manager, from Fluor: an EPC
- Ulrich Siegel, Vice president of Business Development, from Focused Energy: a private fusion company
