PFAS underpin today's highest‑performing PEM fuel cells and electrolyzers...and other systems.
They also just got excluded from my business insurance.

If you work with PFAS in hydrogen tech, the risk isn’t "future" anymore – it’s now.

Sorry NYU Tandon @nyutandon but photo↙️
1️⃣Is not the Fusina hydrogen power plant outside of Venice, Italy
2️⃣Is the Porto Marghera petrochemical plant; Fusina was across a shipping canal↘️
3️⃣In 2009 16MWe Fusina was the world's 1st 100% #H2 power plant
4️⃣Closed 2018: lost byproduct H2 supply

Yes, promising new lab test results for a new PtNiCoOx hydrogen evolution catalyst that uses 5x less platinum.↙️

BUT NOTE that their "durability tests showed...stable performance over 24 h". ↘️

MUCH more work remains before this can go commercial!

Canadian MaxPower claims Saskatchewan well natural hydrogen concentrations of 286,000ppm. #h2_view converts 286,000ppm to 6% #H2.⬇️https://bit.ly/45jJBhz

Unsure if that is a typo, or #H2View needs a better grounding in unit conversions. It should be 28.6% hydrogen!

Congrats #MaxPowerMining

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!

Tobe Energy #Tobe_Energy might want to get an electrochemistry consultant on-board to help with both big-picture & small details of their efficiency quest (including some hydrogen safety knowledge...). I'd be happy to talk!

#Tobe_Energy Claim: "Novel application of capacitively coupled resonant effects"
Problem: Sounds just like Joi Scientific: 2019 finally admitted their claim of 200% efficiency producing H2 from untreated seawater was false! NB Power CEO was convicted of fraud and removed from office!

Tobe Energy #Tobe_Energy Claim: "Novel application of capacitively coupled resonant effects".
Problem: Sounds like wishful thinking, as electrochemistry is defined by voltage and current, not capacitance & resonance!

Tobe Energy #Tobe_Energy Claim: "High-voltage, low-current system".
Problem: Process efficiency is inversely proportional to voltage. So high voltage means poor electrical efficiency!

Tobe Energy #Tobe_Energy Claim: "High-voltage, low-current system".
Problem: H2 production is directly proportional to current. So low-current means low H2 production!
