Summary: A chronological timeline of HPQ Silicon’s key milestones from 2024 to 2026, tracing its shift toward battery materials, clean hydrogen, and commercialization.
2024
- May 2024 — PyroGenesis announced its intention to acquire a 50% stake in HPQ Silica Polvere Inc. (HSPI), the fumed-silica venture.
- Q2 2024 — Received all major equipment for the fumed silica reactor pilot plant, with commissioning on track.
- July 2024 — Entered a Letter of Intent with a global fumed silica manufacturer.
- 2024 — Filed a provisional patent for high-throughput silicon-based anode manufacturing; 18650 silicon-anode cells delivered strong performance at 50 cycles.
- Late 2024 — PyroGenesis completed refractory conditioning on the pilot reactor; first process-material tests scheduled for December 2024.
2025
- Early 2025 — Increased equity stake in Novacium SAS.
- H1 2025 — GEN3 silicon anode material achieved 1,000+ charge-cycle retention (~30% above graphite).
- H2 2025 — Commercial-scale production of 18650 (4,000 mAh) and 21700 (6,000 mAh) cells.
- September 2025 — Awarded C$3 million in Canadian government funding for battery-materials scale-up.
- December 2025 — Signed an industrial cooperation agreement with AD-VENTA to advance METAGENE™ hydrogen scale-up.
- Year-end 2025 — ENDURA+ battery certifications completed; QRR silicon-metal program concluded.
2026
- January 2026 — Independent analysis confirmed the pilot-scale reactor produces commercial-grade fumed silica.
- March 2026 — Finalized an increased (strategic) ownership position in Novacium SAS.
- June 2026 — Announced a Letter of Intent with LN Innov’ and Novacium to evaluate a Canadian-based electric-propulsion platform (presented at Eurosatory 2026).
