  • 2026-10-04 15:30 UTC CM-ENERGY-Q01-R09 (own research pass): no NEW H2 cavern is being leached in Germany yet — live projects are conversions (H2CAST Etzel 2 caverns ~90 t from 9 May 2025; EWE Huntorf 1 of 7 NG caverns, H2 end-2027). First new-build = Storengy SaltHy Harsefeld: borehole 2026, Solung 2027–2032, ops 2032, 2nd 2034; ~7,000 t H2 per 0.5–0.8 Mm³ cavern (salthy.de, quoted). → ≈233 GWh_H2/cavern if working gas (152–163 if total) vs R07's 117–133 → R07's ~100 new caverns becomes ~55–84; but 5-yr leaching (vs R08b 1.3 yr) and 6 yr borehole→ops push a 2026 restart's 55–84 caverns to ~2037–40. Brine/yr unchanged; concurrent strings ×4. results/cm_energy_q01_r09.json. Break this: SaltHy working-gas figure, or a 2006–14 cavern leached >3 yr.
