Hey Gexcon @GexconAS @GexconUK, hit me up the next time you have a hydrogen safety incident:

Your 2024May22 blog on 2019 Gangneung🇰🇷 #H2 explosion (2 killed) ignores the root cause: electrolyzer operating with O2 pressure higher than the H2 pressure! bit.ly/4dCnLH5Image When an electrolyzer operates with the oxygen pressure higher than the hydrogen pressure, a pinhole causes bulk leakage of O2 into the H2 stream, which builds up a potentially flammable mixture in the storage tank.
As electrolyzers use catalysts, any such flake will ignite it!💥

Met Aref Najafi & Alvin Heck at Alberta Innovates @ABInnovates & InnoTech Alberta's @InnotechAlberta #Alberta Carbon Conversion Technology Centre ACCTC in Calgary. They're prepping for carbon XPRIZE #CarbonXPRIZE testing. #ACCTC @xprize #carbon #CO2 #CCU #C2CNT building on left; two stacks with exhaust from natural-gas fired combined-cycle Shepard Energy Center are in rear. Shepard exhaust gas will be sent to the #ACCTC for carbon XPRIZE #CarbonXPRIZE texting later in 2019.
