🔥Follow-up on SK Energy's Ulsan, Korea refinery explosion: 2nd person dies.

🔥Follow-up #2: If the @h2_view story is true↙️, not just residual hydrogen leaked & exploded when the pipeline was opened, but the #H2 gas supply was not isolated! #SOP must include a double block-and-bleed! ↘️

🔥 Fire at hydrogen production unit in SK Energy Ulsan, Korea refinery injures 5. ↙️
↘️ Likely root cause: failure to follow standard operating procedure #SOP & purge residual hydrogen gas from pipeline before opening the line. Released gas cloud exploded.

Shoot a Type IV carbon-fiber fuel cell electric vehicle #FCEV hydrogen storage tank with a small caliber bullet and it bounces off. A .50-caliber bullet makes a hole but no fire as the #hydrogen is released.⬇️
Try that with a battery pack.

I hope Supercritical Solutions Ltd #SSL told Shell Ventures #Shell & Toyota Ventures #Toyota that #SSL electrolyzers produce flammable🔥 hydrogen-oxygen gas mixes!

Granted patent GB2605761 has 0 data.

But WIPO pending app ⬇️ WO2024061976A3 by #SSL shows:

- 22% H2 in anode O2 (5.5x above 4% lower flammability limit #LFL)🔥
- 11-12% O2 in cathode H2 (2x below 6% upper flammability limit #UFL)🔥

I need to let UK HSE Solutions know #SSL is totally unsafe!
