Reply to comment by paulHarkonen in Why do we use phase change refrigerants? by samskiter

Ahh okay I haven't encountered cases of that.

At least in Europe there are some underground storage facilities, basically stored in underground caverns (wells) for that very purpose.

They use depleted wells for long term storage of compressed gas but some places also use LNG for on system peak shaving. It sounds from your comment like it's reasonably common to use some processed natural gas (presumably with all the heavies extracted) as the refrigerant feeding the cryogenic heat exchangers.

Thanks.
