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.

We need a better-educated public.
Yes, hydrogen is lighter than air. So is methane (natural gas). But both are flammable, and should not be used to fill party balloons!🔥🚒
A little googling finds many balloon explosions, mainly in China and India.⬇️

World's first 100% hydrogen power plant in Fusina, Italy (near Venice.)

#hydrogen101
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

#Hydrogen101
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 they need a better grounding in unit conversions. It should be 28.6% hydrogen!

Congrats #MaxPowerMining

Talking about AI slop!

This site even says "Preparing for AGI, ASI, and beyond Sustainable Intelligence Evolution Training HubIt was designed with."

(Ignoring the fact that Metal-Hydride Hydrogen Storage has issues...)

⬇️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 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 convicted of fraud!

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!

#Hydrogen101 #thread /5
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!

#Hydrogen101 #thread /4
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!

#Hydrogen101 #thread /3
Tobe Energy #Tobe_Energy Claim: 42.23 kWh/kg H2 = 94.7% LHV
Problem: They don't know difference between hydrogen's HHV & LHV: 33.32 ÷ 42.23 = 78.9% LHV, not 94.7%!

Tobe Energy #Tobe_Energy Primary Problem: Can't sell their device in US, as NFPA-2 13.3.1.1.2 requires water electrolyzers to be listed or approved↙️, such as with @isostandards⬇️. ISO 22734 requires a membrane between H2 & O2 gases↘️, so membrane-free = NOT ALLOWED!

#Hydrogen101 #thread /1

Underground hydrogen storage is a method proven worldwide to save massive H2 kilograms for later chemical use or for power generation.

Think of that: 1 H2 site = 2x-3x ALL US grid-connected #BESS !

Sure, it's easy to make turquoise hydrogen & solid carbon from natgas / biogas in a lab-scale high-temperature pyrolysis reactor...

But remember, work on the Kværner process began in the 1980's, Monolith bought the IP in 2013, & mothballed their OC1 plant this summer.

Always check for the truth in the hydrogen vertical, whether it is hydrogen production / hydrogen fuel cell performance claims or touting for penny stocks:

J4 just acquired some mineral claims from Primary Hydrogen, there was NO merger!
