How can electrical energy be stored in liquids?
Absolutely. The only what you need is a reversible, first-order phase transition where the phase with the higher energy is liquid. For example, in a <0C environment, you can store energy in liquid water. If you meld a cup of ice (store energy in it), and as it freezes down, it releases that energy. Thus it works as an energy storage.
