Two dead & 19 injured after a volatile reaction at a silver recovery plant in WV 22Apr2026.
Nitric acid mixed with "M2000A" evolved toxic hydrogen sulfide gas.
FWIW: the possible double displacement reaction:
2 Na₂S + 4 HNO₃ → 2 H₂S + 4 NaNO₃

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!]

Oh sure, we need to convert as much green hydrogen to green ammonia as possible...says nobody aware of the severe health hazards of ammonia!
Hundreds got evacuated in Weatherford, Oklahoma; 34 hospitalized, several in critical condition, but nobody died!

HD Hyundai HHI now has ammonia-fueled 2.2MWe & 5.4MWe dual-fuel DI ICE engines.↙️
Hyundai claims a Selective Catalytic Reduction #SCR system will eliminate toxic ammonia & nitrogen oxide emissions.↘️
NOTE: SCR systems are ineffective on cold starts!
-They need high temperatures (around 200C - 250C) to work, leading to high temporary ammonia & NOx emissions.
-The Immediately Dangerous to Life or Health #IDLH concentration for ammonia is 300 parts per million (ppm)! #woops

NOW: Chinese hydrogen electrolyzers from 3 vendors are still not operating due to "too high" grid power price.↙️🤥
11Dec2023: It was "…due to…missing safety features in the system design and lower-than-promised efficiencies."↘️
