The US already has 330GWh of hydrogen storage in operation, of which 90GWh has been in use since 1983. You store it at around 200 bar in salt caverns. The technology is well established, for decades at this point. Last I checked, the projected storage capacity in Europe alone is in the tens-to-hundreds of PWh. The US is somewhere in the same ballpark.

- coderenegade 5y agoAFAIK, the Praxair and Air Liquide sites are bulk storage for hydrogen supply lines running through Texas. I'd imagine the ConocoPhilips site is similar. As for what the hydrogen is used for? Probably for oil and gas extraction, though there's zero reason the technology couldn't be appropriated for storing and distributing green hydrogen.
