💥Birthday party balloons filled with hydrogen exploded in a Bali restaurant on Sunday 30Aug2026, sparking an inferno.

More dangerous fall-out due to the Strait of Hormuz driving up helium prices!

↙️Clean Power Hydrogen #CPH2 funds pivot from water electrolyzer hardware dev to IP licensing.

↘️Too bad their hardware can't be sold in the US or any other country that requires listing or approval (i.e. a membrane separating H2 & O2 per ISO 22734)!

Why did Clean Power Hydrogen #CPH2 think they could build a #hydrogen electrolyzer that was prohibited by int'l safety codes, given their:

"…admitting it did not have the 'financial, engineering, or technical' resources."

I'm just glad nobody was killed.

↙️NASA Glenn preps another regenerative fuel cell #RFC test stand for energy storage on moon or mars.

↘️NASA's 2004 closed loop #RFC tests were also at Glenn (née Lewis).

But #NASA had an electrolyzer explosion when their PC-based control system crashed! Luckily, nobody was injured.

Human-safety says "use a proper emergency shutdown system #ESD". Program manager Dave Bentz added one before they restarted (with a new electrolyzer...).

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!

Some say any hydrogen in pipelines would not be safe.

That is true, if the pipeline is old and there is bad preventive maintenance. Just ask #MNenergy peeps in Minnesota, where a #NNGCompany pipeline explosion left hundreds without natural gas.

How can a French factory reopen after an explosion kills 2 workers, without finding the cause of the blast?

Silicone plants often use hydrogen; unsafe #hydrogen levels can explode; 1 died in this plant in 2016 & a 2nd safety incident in 2025!!

It makes me wonder if this plant is under new US "safety" regulations, or still follows EU requirements...[insert smirk emoji here!]

💥Hydrogen explosion at Elkem silicone factory near Lyon, France injures 4, 3 seriously. Plant has had numerous safety problems, including 1 fatality in 2016.

Might be similar to 2019 Illinois, US silicon hydride plant SiH explosion.

💥Hydrogen explosion in an engineering laboratory at the University of Tehran #UnivOfTehran . 1 dead; 4 injured.

1) How can one say↙️ "suitable for use in practical alkaline water electrolysis" ↘️ when at only 900hr the 1A/cm2 hydrogen crossover ↘️↘️ becomes 0.9% H2 in O2 #HTO, or 22.5% of the lower flammability limit #LFL for #H2 in #O2?
ISO-22734 requires shutdown at 2% H2, or 50% of the #LFL! Extrapolation shows that 2% H2 would be reached in only 1,100 more hours of operation!
2) RE: "without significant damage to the membrane" - I'd say a 4x increase in #HTO at 900hr is "damage", wouldn't you??

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.

3)O2 in #H2
