After two years of testing 24 electric vehicles: Austrian federal police are abandoning #EV for their frontline response cars and reassigning them to administrative duties. The reason? Too many battery-related problems and limitations for emergency response. via GTranslate

Especially timely these days was Eisenhower after his 1945 visit to Ohrdruf concentration camp: I made the visit deliberately, in order to be in a position to give first-hand evidence of these things if ever, in the future, there develops a tendency to charge these allegations merely to 'propaganda.

A group of Whyalla high school students is heading to Switzerland to race a remote-control hydrogen-powered car that they designed and engineered.  #science #technology #education #engineering

It's pretty ironic that even when a hydrogen bus catches on fire, it's actually a battery fire and the hydrogen tanks never burned.

#GeologicHydrogen ⬇️Iowa Rep Elinor A. Levin @levinforiowa.bsky.social recent newsletter updates legislative activity for geologic hydrogen. Looks like some problems in the bill still need fixing. I plan on asking her if the bill covers both #WhiteHydrogen & #OrangeHydrogen... #hydrogen #H2

I would rather buy a Toyota PEM fuel cell system for my data center than a Bloom SOFC system: 1) Toyota individual cells are much larger than Bloom's, meaning fewer stacks, gas/air/power/safety connections, & lower cost. 2) Toyota individual cells run at a higher power rating than Bloom's, so ditto.

Mexico's Chamber of Deputies approved 450-0 a bill adding a formal legal definition of "renewable hydrogen" to the General Law on Climate Change. The bill now heads to the Senate for constitutional review and a vote.

#hydrogen101 ☹️I feel sorry for these authors who embarrassed themselves by not even referring to a basic electrochemistry text! #electrochemistry101 tells you that as the electrolyzer input power increases from zero, the efficiency decreases. The obverse is true as well #H2 #hydrogen #GreenHydrogen

#EnergyBsky Gee, I wonder if the US funding cuts are finally affecting our National Laboratories? Sandia @sandialabs.bsky.social wants to outsource leadership of the National Consortium for the Advancement of Long Duration Energy Storage #LDES Technologies, but won't pay a penny towards the job!

Hey @smallbizmajority.bsky.social , how does @NASA “support small businesses” while killing the NASA Vendor Database #NVDB today? Is this the playbook now: shut the door on small innovators? Are the SBIR and STTR programs next, @warren.senate.gov & @markey.senate.gov ?

↙️Sorry China, your "first coal fuel cell" is 130 years too late. ↘️In 1896 Jacques got a US patent for what he thought was a direct coal (or carbon) fuel cell #DCFC. He actually made a direct coal battery. Subsequent workers made true #DCFC using molten carbonate fuel cell tech.

Yes, exciting shifts in green hydrogen for zero-emissions vehicle #ZEV transportation, but don't forget that 65% of current #hydrogen production is used for ammonia & methanol! Those two industrial uses represent perfect early-adopters for #greenhydrogen! #H2 #ammonia #methanol

I will chug dihydrogen monoxide right in front of you.

All these advances were achieved while maintaining the high level of durability that already distinguished the BZA150: a service life of 25,000 hours. In a heavy-duty truck, this corresponds to a service life of 10 years – comparable to modern diesel engines. bit.ly/4vPa2qU #fuelcell #trucking

Trump's 2025 gutting of USAID led to a severe global health crises, with over 760,000, preventable deaths due to cuts in HIV, malaria, & tuberculosis aid. The actions resulted in massive aid shutdowns, risking health care access for 95 million people & education for 23 million children.

Chinese scientists appear to worry about the "publish or perish" paradigm as well: Their "breakthrough" in direct seawater hydrogen production research? They "...proposed a systematic assessment framework..." No test data. No modeling data. Not even a new theory. Just a framework! #SMDH

Hey @torsolarfred.bsky.social, if the Merino Energy website FAQ describes their Mono heat pump as "It can be installed on any external-facing wall.", isn't it false advertising that they use photos of it on an interior wall?↙️ Just look at those 2 giant outside air connections!↘️
