Your Source for Open Science and Emerging Energy Technology in the Field of LENR
May 2026 brought continued post-IWAHLM-17 momentum, with commercial updates from Brillouin Energy, Clean Planet, HYLENR, New Hydrogen Fusion Energy, ASTRAL Systems, and several community-tracked projects. On the research side, JCMNS Volume 41, Edmund Storms’ latest paper, a muon-assisted p–B11 fusion proposal, zeptojoule calorimetry, and Solitonix-related tritium discussions drew attention across the LENR / CMNS community.
LENR Commercial News:
1.) Brillouin Energy Corp. makes bold move toward commercialization
Brillouin Energy announced that Greg Knight has joined the company as Executive Chairman. The company says it has transitioned from laboratory research to an integrated, closed-loop development platform combining in-house manufacturing, testing, and high-frequency data capture to accelerate system development.
Brillouin also reports that Tim Mellon completed the company’s Series C Preferred Stock round, initiated the current Series D Preferred Stock round with a lead investment, and contributed 36 acres of industrially zoned land in Connecticut for future development. (markets.businessinsider.com)

2.) Clean Planet / QHe — Kishida visit and pilot-roadmap discussion
Clean Planet reported that former Japanese Prime Minister Fumio Kishida visited its KAWASAKI Base technology development site on May 20, 2026, where he viewed QHe demonstration equipment and heard explanations from Professor Emeritus Jirota Kasagi and Professor Emeritus Hiroshi Toki.

The forum-circulated attachment says Clean Planet founder Hideki Yoshino discussed the company’s technology and pilot plans. I could not independently verify the exact “pilot plant running in 2027” wording from a public Clean Planet page in this pass. A public 2023 Clean Planet/Nikkei XTech PDF instead states that Clean Planet planned to build a pilot plant in Kawasaki by 2030.
3.) HYLENR is hiring
HYLENR continues to present its work as lattice confinement fusion, emphasizing compact solid-state reactor systems for heat and power rather than large plasma machines.
A LinkedIn hiring post circulated by Shaik Pasha shows HYLENR recruitment activity for clean-energy / LENR-related roles. Treat this as a hiring/community update, not as technical validation.
4.) New Hydrogen Fusion Energy — Aichi exhibition and updated ResearchGate paper
New Hydrogen Fusion Energy says it will exhibit at the New Aichi Creative Research and Development Exhibition, June 3–5, 2026, at Aichi Sky Expo. The company says it will introduce a “tabletop miniature heater using nuclear fusion reaction heat” and give a presentation on a new principle of nuclear fusion. New Hydrogen Energy
NHFE’s updated ResearchGate status paper states that new powder materials have enhanced excess-power levels to over 3 W/g-Ni, while also saying the company does not currently plan to disclose details of its latest progress. This remains a company-authored ResearchGate paper and should be treated accordingly.
5.) ASTRAL Systems reports continued progress
ASTRAL Systems describes its work as compact fusion systems for particle flux, irradiation, medical, industrial, and research applications. Its May news page reports a technical milestone of 60 hours of continuous DT irradiation.
Papers:
1.) Edmund Storms — A Comprehensive Understanding of Cold Fusion
Edmund Storms’ new paper, A Comprehensive Understanding of Cold Fusion, argues that hydrogen-isotope fusion has been demonstrated in a variety of specially treated materials and proposes a testable explanatory model. The abstract includes Storms’ proposed 4.01841 mass value for hydrogen-4, which he proposes decays rapidly to helium-4 by beta emission.
2.) JCMNS Volume 41
LENR-CANR’s most-recent-papers listing now shows JCMNS Volume 41 entries for 2026, including Yasuhiro Iwamura’s paper on the current status of CMNS R&D in Japan. (LENR-CANR)
ISCMNS describes the Journal of Condensed Matter Nuclear Science as an open-access journal covering nuclear processes in condensed matter, including calorimetry, metal hydrides/deuterides, nuclear products, transmutation, induced radioactivity, accelerator experiments, and theoretical models.
3.) Muon-assisted proton–boron-11 fusion
The arXiv paper A novel approach to proton-boron-11 fusion proposes enhancing low-energy p–B11 fusion by first forming muonic hydrogen and then bombarding it with boron-11. The authors report that the muon cloud can reduce the effective Coulomb barrier and increase tunneling probability at incident energies below 100 keV.
This is not LENR in the narrow Pd-D / Ni-H sense, but it is relevant to broader low-energy fusion, screening, and Coulomb-barrier discussions.
4.) Nuclear relaxation as a proposed “third pathway”
A forum-circulated paper titled Nuclear relaxation is the 3rd pathway argues that LENR may involve context-dependent nuclear dynamics in anisotropic, defect-rich, hydrogen-loaded environments, rather than simply small corrections to existing nuclear models. Treat this as a theoretical proposal, not an established mechanism.
5.) Zeptojoule calorimetry
Gunyhó, Kohvakka, Chen, Girard, Kokkoniemi, Liu, and Möttönen published Zeptojoule calorimetry in Nature Electronics. The paper reports measurement of 1-microsecond, 8.4-GHz microwave pulses with full-width-at-half-maximum energy resolution finer than 0.95 ± 0.02 zJ, corresponding to 5.9 ± 0.12 meV or about 170 photons at 8.4 GHz.
This is not a direct LENR paper, but it is highly relevant to future CMNS instrumentation because ultra-sensitive calorimetry could support low-signal heat, RF, photon, and quantum-energy detection work.
6.) Solitonix / tritium witness statement update
Maurizio Maggiore’s updated ResearchGate witness statement says a Solitonix tritium-producing experiment report was integrated with results from a newer machine version shown at IWAHLM in Bergamo, including additional spectrometric data.
This should be presented as a witness statement, not independent replication. A related LENR-CANR paper by Righes et al. reports reproducible tritium production in a pulsed system and is useful background for readers following this line of claims.
Patents:
A patent we missed back in February from Kobe University, titled “Method for producing He-3, nuclear reaction generating device, and nuclear reaction generating method.”

NASA JPL reported that a prototype lithium-fed magnetoplasmadynamic thruster was tested in February 2026 and publicly announced on April 28, 2026. JPL says that with further development, such thrusters could support nuclear electric propulsion for future Mars missions.
NASA Jet Propulsion Laboratory (JPL)
This is not directly LENR, but it is relevant to advanced nucleonics, high-power electric propulsion, lithium plasma, and nuclear-electric mission architectures.
2.) The Debrief energy coverage
The Debrief’s energy section continues to cover advanced-energy, vacuum-energy, fusion, plasma, materials, and unconventional-energy stories. May 2026 entries include coverage of a claimed quantum-vacuum “MicroSparc” device and other emerging-energy topics.
3.) AI-assisted commercial landscape round-up
A LinkedIn article titled The 5 hottest cold fusion startups summarizes the current commercial LENR landscape and frames 2025–2026 as a period of renewed institutional, investor, and startup activity. Treat this as media commentary and market mapping, not technical validation.
Videos Worth Watching:
1.) Sabine Hossenfelder — “I Looked at the New Cold Fusion Breakthroughs. It’s Complicated”
Sabine Hossenfelder posted a May 2026 video and blog entry discussing renewed investor interest in cold fusion / LENR companies and asking whether the current wave of commercial claims represents real progress or speculative tech-bubble dynamics.
A lively LENR-Forum discussion followed under the thread: “Sabine 5/24/2026 video: Are all the ‘start-ups’ an asset, or liability to LENR?” LENR Forum
2.) Solid-State Fusion videos and interviews
Solid-State Fusion continues to host LENR / solid-state fusion videos and interviews, including ICCF-related materials and community education resources.
