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.

UNTRUE: flow sheet shows O2 could travel with liquid mediator to catalytic hydrogen generator.

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.

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

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...

Naysayers warn that hydrogen leaks are explosive—but the same is true for any flammable gas, including natural gas in your kitchen. A spark from static electricity is enough to ignite!⚡️

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)!
