Fusion race: $10B bill, ENN's H-B groundbreak, UK sprint
Where it stands: Fusion is drawing public money and private capital on several continents: a bipartisan US bill proposes $10 billion for commercialization, Germany launched a milestone-based programme, and Commerce signed letters of intent with Helion and Commonwealth Fusion Systems. Hardware and physics are moving too, with ENN breaking ground on its hydrogen-boron Helong-2 in China on a 2030 electricity claim and General Fusion measuring a 1.1 keV electron temperature. Watch the $10 billion bill's committee fate and whether ENN's 2030 claim holds up.
Latest
- 2026-10-30DIII-D National Fusion Facility researchers published a Physical Review Letters paper describing the first experimental confirmation of helicon current drive, a method that could be used to operate a steady-state tokamak in regimes relevant for fusion power (American Nuclear Society). Development: the research layer beside ITER hardware, the IPP–Columbia center, and the Proxima supply-chain signings — a peer-reviewed physics first rather than a commercial claim. Watch: replication by other teams, integration into steady-state reactor design studies, uptake by commercial tokamak developers.
AI image - 2026-10-28 (~12:25 PM ET, tech.eu — tech.eu/2026): Proxima Fusion signed partnerships with Fujikura (superconducting tape manufacturing) and Kyoto Fusioneering (plasma heating and fuel) to strengthen Germany's fusion supply chain. Development: the Kyoto Fusioneering axis gains a second tie beside the DIII-D power-exhaust partnership (Oct 15), and the thread's supply-chain layer gains a European-reactor-developer × Japanese-supplier lane. Partnership-grade: no volumes, dollar figures, or delivery dates in coverage. Watch: whether the partnerships firm into supply orders, scope detail, and first deliveries.
- 2026-10-28 (~5:25 PM ET, ANS — ans.org/news): Commerce announced signing four letters of intent for federal R&D awards under the CHIPS and Science Act focused on semiconductors and power electronics — including awards for fusion companies Helion and Commonwealth Fusion Systems. A second federal channel for fusion money beside the DOE lanes (Milestone-Based Fusion Development Program — Xcimer up to $30.5M, Oct 6 — and the Genesis Mission rounds): these awards route through Commerce and target semiconductor/power-electronics supply chains rather than reactors. LOI/intent grade: no dollar figures, award terms, or the other two signatories named in coverage. Watch: LOI-to-award conversion, per-company amounts, and which semiconductor/power-electronics capabilities Helion and CFS develop under the awards.

- 2026-10-23 (claims layer, single-source): Marathon Fusion's mercury-to-gold claim got its second explainer (NDTV Profit, pub ~4:25 AM ET — ndtvprofit.com/business) — a detailed walk-through of what the company says it did: converting mercury into stable gold via a process involving fusion neutrons, restating the 2025 paper's ~2 tonnes of gold annually from a suitably designed fusion plant (framed against CERN's demonstrated transmutation record as a ~10x multiple). Second outlet on the lane after the Oct 22 skeptical explainer; the evidentiary state is unchanged — no demonstration plant, named partner reactor developer or utility, or independent verification in the article. Watch: independent assessment of the yield math, and a named partner reactor developer or utility.
- 2026-10-22 (claims layer, single-source, ~4:25 AM ET article time — MSN: msn.com/en-in): Marathon Fusion's mercury-to-gold claim surfaced as a skeptical explainer — the company's 2025 paper estimates a suitably designed fusion plant could produce ~2 tonnes of gold annually, framed against CERN's demonstrated transmutation record as a ~10x multiple. Isotope-transmutation-for-precious-metals is a new lane on this thread — claims-grade only: no demonstration plant, partner reactor developer, or independent verification in the article, and the piece's own framing interrogates whether "modern alchemy" can work. Watch: independent assessment of the paper's yield math, and a named partner reactor developer or utility.
- 2026-10-21 (research layer): IPP (Max Planck Institute for Plasma Physics, Germany) and Columbia University established the Max Planck Columbia Center — a new "virtual," joint transatlantic fusion energy research center, co-directed by IPP director Thomas Klinger and Columbia associate professor of applied physics and applied mathematics Carlos Paz-Soldan, who also directs the Columbia Fusion Research Center (ANS, pub ~2:49 PM ET — ans.org/news). First German-institute × US-university institutional tie on the thread's file (the thread's German lane to date: SPRIND's milestone-based fusion programme, Oct 14). Announced-only: no funding, staffing, or joint-research agenda in the article. Watch: disclosed funding and support, first joint programs or experimental campaigns, and whether the virtual structure produces staff exchanges or shared diagnostics.
- 2026-10-15 (capital layer, single-source): Cambridge Heavy Industries, a Massachusetts-based fusion startup, raised $6.2 million in seed funding to develop a compact fusion reactor (Digital Market Reports, pub ~4:25 AM ET) — the smallest capital close on the thread's file so far (vs Type One's $200M Series B and Helical Fusion's ¥3.23B/~$22M second close, both Oct, ledgered), and syndication-grade only: no investor names, reactor approach, or timeline in the reporting; no primary coverage found. Watch: named investors, reactor approach, an origin press release. digitalmarketreports.com/news
- 2026-10-15 (tokamak supply layer): DIII-D National Fusion Facility to partner with Kyoto Fusioneering to design, manufacture, install, and operate a new power exhaust system advancing a negative-triangularity approach toward commercialization (ANS, ~9:06 AM ET Oct 15 — ans.org/news); announced the week before the report and building on the company's ORNL partnership announced earlier in 2026. First DIII-D supplier-hardware entry and a second US-lab tie for Kyoto Fusioneering on the record. Watch: install timeline, negative-triangularity experimental results, further US-lab expansion.
- 2026-10-14 Germany launches its own milestone-based fusion programme (ANS): SPRIND (Federal Agency for Breakthrough Innovation) established a milestone-based fusion programme on behalf of the Federal Ministry of Research, Technology, and Space (BMFTR), as part of the government's High-Tech Agenda Germany (HTAD) — technology-specific roadmaps and flagship programmes to speed research-to-application. The German state's fusion lane (previously limited on this thread to converting a major ex-nuclear plant into a fusion laser lab) gains a funded programme layer, and the milestone-based structure echoes the US DOE Milestone-Based Fusion Development Program (Xcimer's up-to-$30.5M, Oct 6, on this thread). Watch: initial awardees/milestones under SPRIND, HTAD flagship detail. Link: ans.org/news
- 2026-10-08→09 (three milestones, two capital closes): (1) General Fusion's MTF milestone: 1.1 keV (~12.6M °C) electron temperature measured by Thomson scattering just before peak compression on LM26 — a world-first for the MTF approach, co-authored with UKAEA (ANS + press release). (2) Helical Fusion's Series B second close: ¥3.23B (~$22M at ~145 JPY/USD) — Fuji Electric as strategic investor/partner, Fujikura and Tokyo Gas in; Helix HARUKA construction advancing under Japan's public-private frame. (3) The Type One second-source layer (Oct 7, plus an ETSU talk by Dr. Nicholas Eidietis Oct 26 — the Tennessee project's public-engagement cadence). Watch: LM26's next milestone (compression), HARUKA's schedule, whether DOE's milestone program adds names.
- 2026-10-06 two items. (1) Xcimer Energy (Denver) finalized up to $30.5M in DOE's Milestone-Based Fusion Development Program, budget period 2 (POWER) — the laser approach keeps its federal lane. (2) Corporate fusion news: Type One's $200M Series B and the 2034 Infinity Two date (ledgered); PPPL's "heat first, compress later" ignition strategy explainer (Interesting Engineering) is research commentary — verify against the paper before claim-grade use.
- 2026-10-05 (ITER hardware completes): Fusion for Energy (+ Ansaldo Nucleare, Westinghouse, Walter Tosto) delivered Europe's final vacuum vessel sector for ITER at Cadarache — the international project's construction program reaching its hardware milestone; no schedule claim attached in the reporting. Watch: assembly integration dates vs ITER's baseline-slippage history.
- 2026-10-03 California's SB 925 fusion-framework item went on the record in the California state-policy thread instead of this one.
