...sustainable.
If one searches Google scholar, with the search terms, hydrogen, electrocatalyst, "platinum free" one will come up with close to 4000 hits, 484 of which have been published since the beginning of 2025, 62 in 2026.
There are no papers published anywhere, however, that can overturn the laws of thermodynamics - one of which, the 2nd, means that storing energy wastes energy.
The "energy storage is green crap" is handed out by people who haven't noticed that the trillions of dollars squandered on so called "renewable energy" has had no environmental benefit, that the the only result of tearing the shit out of the planet for mines, destroying pristine wilderness for solar and wind industrial parks has had no other effect than making the collapse of the planetary atmosphere occur accelerate faster. Both the second derivative and even the third derivative of the experimentally determined rate of accumulation of the dangerous fossil fuel waste carbon dioxide are positive.
It's an ignorant affectation to hype energy storage, particularly as an industrially problematic gas, hydrogen, which has the 3rd lowest critical temperature of all known gases, the others being 4He and the decay product of tritium, 3He.
The real purpose of hydrogen hype is to greenwash dangerous fossil fuels.
The Journal of Hydrogen Energy published its first issue in 1976:
International Journal of Hydrogen Energy
Hydrogen was a bad idea in 1976, 1986, 1996, 2006, 2016, and remains one in 2026.
Have a nice day tomorrow.
