↙️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.

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!

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.

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.

The European Commission highlights hydrogen as an important energy carrier and chemical feedstock that could help decarbonise sectors otherwise deemed hard-to-abate. Europe’s existing natural gas grid is seen as a promising asset to repurpose for the transportation of hydrogen. This technical report provides a literature review of hydrogen's impact on pipeline materials, particularly steel and polymers. Hydrogen is known to reduce the ductility, fracture toughness, and the fatigue crack growth resistance of steel materials commonly found in transmission pipelines. It is also known to permeate through polymeric materials that are often used in the distribution grid. The possible implications for pipeline integrity and safety are reviewed. This report emphasises the need for further experimental research and practical experience combining material science and safety engineering disciplines. Key areas lacking knowledge include the full- or large-scale validation on pipeline sections of small-scale laboratory results, the behaviour of typical pipeline defects, and the long-term performance of polymeric pipeline materials, all under the influence of gaseous hydrogen. The report highlights the essential role of testing facilities such as the High-Pressure Gas Testing Facility (GasTeF) of the European Commission’s Joint Research Centre in addressing these gaps.
