We already have a liquid which stores energy for years: water.

When the sun is shining, or the wind is blowing, water can be pumped 
from a low to high reservoir. When energy is needed, the water runs back 
down to turn a turbine. ANU researchers found thousands of sites 
suitable for pumped hydro, and won the Eureka Prize for this work.

The Murray–Darling Basin Authority are trying an even simpler scheme: 
release water for irrigation at the time of day when energy is needed. 
But they need to test this intermittent flow doesn't adversely effect 
water users, or the river:
