I know that only mice were involved in these inhalation therapy experiments, but 7% hydrogen in air is almost twice the flammability limit of 4%!💥

Don't forget about the humans who ran these lab experiments and were put in danger!

RE: Clyde Hydrogen demo of integrated decoupled electrolyzer prototype.

⬇️Claim "Safety-no possibility of #hydrogen and #oxygen mixing"

UNTRUE: flow sheet shows O2 could travel with liquid mediator to catalytic hydrogen generator.
H2 + O2 = BAD!

In Oman, Netherlands' H2-Fuel & HydroFlexx ↙️lie about their "new" powdered sodium borohydride hydrogen carrier:
-NaBH4→H2 not a new idea (ca. 1950s)
-High #hydrogen density-NO (lower than 700Bar gaseous #H2 )↘️
-Non-flammable-NO↘️↘️
-Non-toxic-NO↘️↘️

Es erheitert mich immer wieder wie überraschend simple physikalische Gegebenheiten für einige "Experten" in der EU sind,wobei eine einfache Googlesuche hier helfen kann :
H2 ist das kleinste Atom, diffundiert also durch die dicksten Stahlflaschen/leitungen in kürzester Zeit => Lagerung/Transport nur flüssig oder hoher Druck.
Erfahrungen:: BWM Flughafen Münch.+ Betreiber von H2 Tanke.

#Wasserstoff gilt als Hoffnungsträger für die #Dekarbonisierung, doch beim Transport durch bestehende #Erdgasleitungen gibt es #Sicherheitsrisiken.

Wasserstoff macht Stahl spröder, schwächt die #Bruchfestigkeit und durchdringt #Kunststoffe. Ein Bericht der EU zeigt, dass viele Fragen zur Materialbeständigkeit und #Sicherheit im Dauerbetrieb noch offen sind.

🎆 🔥 2025Mar31 Korea Supreme Court: +10B won US$6.8MM damages award for 2019 Gangneung hydrogen explosion, which killed 2 injured 6
1) No oxygen monitor on #hydrogen gas produced by electrolyzer
2) Unqualified incompetent company was in charge!

Conclusion: use qualified people who know #H2 safety

Hydrogen fuel cell lab explosion in Yongin, South Korea sends 5 to hospital with minor injuries via @hydrogeninsight

My view from 6899mi away: plastic tubing (🟧below) was used for #hydrogen gas & failed. 🟥circle shows the melted end of a tube!

Why is Supercritical Solutions Ltd #SSL allowed to develop a totally unsafe membrane-free #hydrogen production device?

4 ways #SSL fails @isostandards ISO 22734:
1)No insulating membrane
2)Membrane is porous
3)O2 in #H2
4)H2 in #O2

All it takes is a particle of catalyst (or rust) flaking off and flowing downstream, then BOOM1💥

Here's the link about the 2011Aug09 hydrogen/oxygen #HHO explosion💥 in Los Angeles: 2 maimed, a third injured:

This 2011 accident occurred 14 months after another💥that killed one!
And they had a smaller 💥 in 2008!

Lower flammability limit #LFL for H2 in O2 is 4%.
#HHO is 67% H2 (16.75x higher!) & quite explosive!

💥BOOM! due to the explosive stoichiometric mixture of hydrogen/oxygen, also called HHO, Brown's gas, oxyhydrogen or hydroxy gas.

@lafd.bsky.social photos show what can happen when a speck of rust (or catalyst from the electrodes) ignites the hazardous mixture.

Hey UK Health and Safety Executive #HSE :

Why is Clean Power Hydrogen #CleanPowerH2 allowed to sell a totally unsafe membrane-free #hydrogen production device?

@isostandards ISO 22734 requires:
-Membrane between #H2 & #O2
-Operation below hydrogen's #LFL

Otherwise...
