Flywheels, pumped hydro, batteries, and compressed air are all superior storage methods to hydrogen.

Hydrogen also cannot use the existing pipeline infrastructure. For that synthetic methane would work while being more efficient and actually cleaner than most hydrogen sources.

Flywheels for grid-scale power storage? You're out of your mind.

Compressed air? Very lossy on account of the compressible fluid.

Pumped hydro is great... if you've got the necessary geological features nearby.

Batteries? Well... maybe.

How so?

Your link is paywalled and if you can't explain it yourself you don't actually know what it says anyway.

I already gave you the short explanation, the article contains the details which you’re welcome to read or ignore. As far as paywalls yeah, real work takes money, it isn’t free.

I can however link you to a non-paywalled Q and A with the author which addresses your and some others concerns.

Got it. You have no clue what your talking about and are deflecting. "You're behind the times" is not an explanation. I'm done here.

EDIT: /u/ersatzgiraffe I have to edit to respond due to user blocking:

There are plenty of uses for hydrogen and this sounds like a much better way to produce it at first glance. My point wasn't that hydrogen is bad, just that it's a bad for electrical storage and passenger vehicles.

Japan is working to produce hydrogen as a byproduct of their new meltdown-proof nuclear reactors. It actually may be a new era re: hydrogen generation, because yes, in the 2010s it was incredibly foolhardy to bother electrically creating hydrogen to convert it back to running an electric motor when you could just use electricity directly. This video is three weeks old, so maybe things are changing?
