Description:
Arizona is endowed with incredibly diverse natural beauty, and has also
been blessed with at least seven discrete deposits of bedded salt. These deposits
are dispersed around the state and cover some 2,500 square miles; they currently
contain 14 LPG storage caverns, with preliminary plans for more in the future.
The areal extent and thickness of the deposits creates the opportunity for greatly
expanded storage of LPG, natural gas, and compressed air energy storage
(CABS). The location of salt deposits near Tucson and Phoenix may make CABS
an attractive prospect in the future. The diversity of both locations and evaporite
characteristics allows for much tailoring of individual operations to meet specific
requirements.
