Korea Minister of Employment and Labor Kim Young-hoon issued an emergency directive on the 17th (the same day as the most-recent accident) regarding the #H2 explosion.
It is actually the 2nd #hydrogen pipeline accident this year!
Korea needs to establish a culture of hydrogen safety ASAP!

🔥 Fire at hydrogen production unit in SK Energy Ulsan, Korea refinery injures 5. ↙️
↘️ Likely root cause: failure to follow standard operating procedure #SOP & purge residual hydrogen gas from pipeline before opening the line. Released gas cloud exploded.

1959: the world's first fuel cell tractor from Allis-Chalmers ↙️ .
In 2025 it's Kubota's autonomous #fuelcell tractor ↘️ .
Went from 20HP on propane fuel, to 100HP on hydrogen.

So much wrong with this Mazda engine reformer "invention" as well as all the press accounts:↙️
1-It's a PATENT APP, not a PATENT↘️
2-Reformers make CO & CO2, not CARBON!
3-Any C "adhered" to catalyst would quickly STOP reforming reaction
4-Water vapor adsorption would quickly fill-up & STOP
5-Water vapor adsorption GIVES OFF HEAT: you CAN'T PATENT THERMODYNAMICS!
6-Cite JP2021153622A, which PYROLYZES PURE CH4 & DOES'NT REFORM GAS/DIESEL-AIR MIXES!
7- -622a DOESN'T MENTION SOLID C!

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.

Sorry Ricky @TwoBitDaVinci ↙️, the first offshore hydrogen production platform was France's 2023 Lhyfe↘️, followed by UK's 2024 Dolphyn↘️↘️.

BUT Germany's 2025 H2MARE is the 1st offshore platform making offshore #H2 & using on-board direct air captured #CO2 #DAC to make liquid fuels - Power-to-X.

I wish the press would understand the difference between electrolyzer STACKS and SYSTEMS!

There are 14 of the Cummins Accelera @AcceleraZero 2.5MW electrolyzer STACKS↙️ in the Linde Niagara Falls, NY electrolyzer SYSTEM↘️ .

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."↘️

Yes, biomass gasification & pyrolysis are thermal methods of generating hydrogen.
EPFL used light pulses to supply the heat.↙️
My quick calculations: the CAPEX of just the xenon strobe light subsystem to irradiate the 50μm biomass layer↘️ is US$8.5MM per kg #H2!🤑

3) And why invent a new name [Base Load Power Hub #BLPH] for the old, classic name:

Regenerative Fuel Cell #RFC !

NB: #RFC is the general name, and does not mean a unitized regenerative fuel cell #URFC, which uses a single combo electrolyzer stack which can also run as a #fuelcell

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!↘️
