Many researchers are interested in energy storage system which is effective in saving energy and solving electricity peak-on shortage .The working principle

process

thermodynamic properties

and economic comparison of the potential energy storage system which uses H_2O/LiBr as working fluid were analyzed.The results show that this system balances electricity network load

e.g.shift peak-on and peak-off.Moreover

it has other advantages such as its larger energy storage density(400 kJ/kg when its coefficient of performance is 4.3)

feasibility to utilize many kinds of energy resources(solar energy

soil heat energy

industry waste heat and so on)

simple system

and working fluid friendly to our surroundings.It is an economic system that requires less investment and its gross profit is seven times larger than that of ice storage system in ten years.
