Yes, salt mining can be done relatively safely. Yes, a slight subsidence may occur and no, there is no risk of earthquakes.

And just as important: once the salt has been removed from the ground, the remaining cavities are not used for hydrogen storage. That commitment from Nobian and EZK sounded crystal clear last night.
