I worry that emphasizing green H2's (GH2's) environmental edge will mislead the uninitiated into visualizing a pump island with various H2 grades. Where GH2 electricity goes (mobility) and where it comes from (intermittent renewables) is one system. That's what matters.

H2 cars can't precede their support infrastructure, or vice versa. Yet far easier heavy H2 mobility languished for years while cars preoccupied pundits. Einstein said, “The definition of insanity is doing the same thing over and over again, but expecting different results.”

Anyone who follows the hydrogen transition can see that 2035 is shaping up to be electrochemistry's annus mirabilis. Apollo 11 was in 1969. Big Oil didn't cost the climate those 66 years; it was Big Media's nescience. NC (its home state) STILL hasn't heard of 2003's hydrail.

All fuels are eventually subject to depletion. Hydrogen is not. Ergo, it's unhelpful when pundits characterize hydrogen as a fuel when writing for the non-technical public. Hydrogen, copper, electrolyzers, transformers & fuel cells are grid components; NOW the grid has spacetime!

Did the advent of color TV doom democracy? Blue and Red politics supercharged the binary TV news business model where everyone is considered a "them" or an "us." Adrenalin glues ads to brains, irrespective of content. That business model has conjured an army of Iagos. -Desdemona

Thanks to Tim Sasseen at Ballard Power Systems for helping share 18 yrs of hydrail history! "...probably the only paradigm shift of a heavy industrial technology ever planned and executed by a handful of private individuals and academics for societal, non-commercial, reasons."

Thank you, Tim! linkedin.com/pulse/birth-hy…

Luddism, Ink. When the 'Net ate print's lunch, science and business writers lightened-ship. Shooting-and-corruption reporters only dared interview "experts"— for which read old companies dodging disruption by hydrogen and the Green New. Silence and Fear begat "Luddism redux."

To Jenifer A. Sensiba at CleanTechnica Your light rail vs BRT piece would carry more weight if you mentioned that hydrail is now replacing 1880s trolley tech, saving some $10 million a mile in capex and $130K/mile/year in mtc! youtube.com/watch?v=jKOmvY…

Q: Is hydrogen the fuel of the future? A: No, it's the cheaper energy-elastic alternative to copper TODAY.

Most of the reported instances of "making green hydrogen" are actually "harvesting intermittent renewable energy" and storing and/or delivering it via H2 electrochemical technology. The tendency to call H2 a "fuel" is an unfortunate extraction-era meme that muddies the water.

I strongly doubt all conspiracy theories...but IF "Big Oil" planted the impossible idea of pre-truck-stop H2 cars jumping the queue and emerging before H2 semi's, planes or ships in order to stave-off the looming demise of carbon extraction, it's certainly worked wondrous well!

"Blue" hydrogen = licking the icing off a carbon cake.

"Carbon" and "copper" are languages of the extraction epoch; renewables "speak hydrogen."

If the hydrogen transition is to deliver climate change mitigation, media "climate solutions deniers" must be won over as a high priority; the general public needs to be kept acurately and continuously INFORMED ABOUT THE GLOBAL PROGRESS and the economics of the H2 transition.

H2 cars come last, after H2 trains, trucks, ferries, cruise ships, container vessels and airliners. They are like Fortinbras in Hamlet. He only gets a walk-on part at the end...but gets to rule Denmark! Cars are bit players in the H2 drama—but they WILL feature in the big finale!

The two meaningful classes of hydrogen are synthesis- and extraction-derived. Synthesis-sourced H2 enables intermittent sourcing upstream and mobile uses downstream, is inexhaustible and leaves no problematic residue. Extraction-sourced H2: just the mobile use part.

Whether the legitimate basis of governance rests on the choice of the governed (Jefferson, Zelenshyy), or the strength of governors (Lincoln, Putin) is central to politics but never addressed directly in discourse. From ancient Athens to present Kiev, it matters most.

Hydrogen is a renewable energy carrier; nitrogen and carbon can be hydrogen carriers.
