SPAC Aimei Health NASDAQ $AFJK terminates business combination agreement with Chinese United Hydrogen Group Inc. dating to 2024Jun19; triggered by missing the closing date.
#UHG transaction was valued at US$1.6B.

FAW Jiefang hydrogen internal combustion engine #H2ICE reportedly passes National Certification.

-NB: Test engine shown installed on an engine test stand, not with it installed in a tractor & on a dynamometer.
-NB: As with most #H2ICE engines, conventional SCR exhaust aftertreatment was used.

UT Austin #utaustin Jackson School of Geosciences #txgeosciences has been doing great work in the natural, or geologic hydrogen exploration arena

Now they published a paper looking at repurposing underground natural gas storage sites for #hydrogen & CO2 storage

↙️India makes hydrogen from nuclear heat & not much electricity, using the copper-chlorine thermochemical cycle

↘️Some might not be excited, because high-temperature solid oxide electrolyzers #SOEC can already make green hydrogen using ⅓ 🟥nuclear heat & ⅔ 🟩electricity.

Congrats to Japan’s MOL on making hydrogen at sea on th a12m / 39-foot sailing sloop "WINZ MARU", but the Energy Observer @energy_observer vessel was launched in 2017, and made/stored/used hydrogen in its round-the-world trip.

Why did Clean Power Hydrogen #CPH2 think they could build a #hydrogen electrolyzer that was prohibited by int'l safety codes, given their:

"…admitting it did not have the 'financial, engineering, or technical' resources."

I'm just glad nobody was killed.

Japan appears to love the health idea of hydrogen gas possibly neutralizing reactive oxygen.

But, #hydrogen is flammable/explosive.

H2 generation devices are sold to consumers that should be illegal.
↙️A woman's lungs survived such an explosion event!

NOx emissions are a major problem with all hydrogen internal combustion engines, including turboprops. Besides NO and NO2, they often emit N2O.
GWP100 of N2O is 265-300x higher than CO2.
I doubt China is using SCR to limit NOx.
H2 fuel cells have higher efficiency and emit no NOx.

SunHydrogen #sunhydrogeninc spins their weak Austin, TX test results:↙️

1) As my wicked-smart #GinerInc mentor Tony LaConti always said, "there's no such thing as a defect-free coating"

2) There's a good reason Nocera & his artificial leaf startup #SunCatalytix failed on the same task, and pivoted away from PEC!↘️

3) Don't forget, you can always over-build your solar, add a battery, and keep an electrolyzer running 24x7x365!

You've heard you can indict a ham sandwich? Well, you can also patent one!

This "invention" magically spins and separates hydrogen gas #H2 & oxygen gas #O2 from water, then magically separates the #H2 from the #O2 & the water!

Germany's Ostermeier Hydrogen Solutions makes & sells complete small water electrolyzer systems that can run off your solar PV panels for grid independence.
Has compressed hydrogen storage & a fuel cell for Dunkelflaute or seasonal energy storage.
Either PEM or AEM electrolysis tech.

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!

#Hydrogen101 #PFAS101
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.

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 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!

#Hydrogen101 #thread /6
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%!

#Hydrogen101 #thread /2
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
Tobe Energy #Tobe_Energy claims a revolutionary membrane-free water electrolysis process to efficiently make green hydrogen. Let's examine their tech & claims...

In Oman, Netherlands' H2-Fuel & HydroFlexx ↙️lie about their "new" powdered sodium borohydride hydrogen carrier:
-NaBH4→H2 not a new idea (ca. 1950s)
-High #hydrogen density-NO (lower than 700Bar gaseous #H2 )↘️
-Non-flammable-NO↘️↘️
-Non-toxic-NO↘️↘️

1) This CA NIMBY group bases their fears of a hydrogen test in natural gas piping on only a 7% reduction in CO2 emissions.↙️ Ignores CARB plans to ramp up #hydrogen levels in 2030-2040 for greater #CO2 savings!↘️
2) NIMBY group bases their fears on ONE paper, which focuses on efficiency. Paper IGNORES need to meet peak winter SEASONAL demands-#H2 is far cheaper vs the batteries & electric grid upgrades to supply 100% heat pumps!↘️↘️

Shoot a Type IV carbon-fiber fuel cell electric vehicle #FCEV hydrogen storage tank with a small caliber bullet and it bounces off. A .50-caliber bullet makes a hole but no fire as the #hydrogen is released.⬇️
Try that with a battery pack.

Green hydrogen is made commercially with green electricity using water electrolyzers, which operate for +30,000hr.

The #HYScale EU Clean Hydrogen Partnership project aims to improve catalysts and other materials, reducing electrolysis costs.↙️

BUT 330hr is not ready for a TRL5 demonstration!↘️

There are 2 main ways to power a vehicle on land, sea or air with hydrogen:

1-hydrogen fuel cell electric vehicle #hydrogen #FCEV
2-hydrogen internal combustion engine #H2 #ICE

Unfortunately, Sustainability Magazine doesn't follow my feed...↙️

Egli (2025) claims green hydrogen from Africa is too expensive to export.
But since he botched electrolyzer CAPEX, how reliable is the rest?

#LatentDrive claims
- Electrochemical treatment of stainless steel to create #H2 electrolyzer catalyst out of thin air (or thin stainless).
- Electrolyze sea water to make #GreenHydrogen but ZERO chlorine gas (as every other salt water electrolyzer does)

#Hydrogen101
I hope UK's Latent Drive doesn't give the green hydrogen industry a black eye!
#LatentDrive claims lots of stuff with ZERO data.↙️
Their patent applications↘️ focus on electrical engineering, just as Joi Scientific's apps did (before Joi's sea water→ #H2 was admitted to be fraud)
