Abstract
A system and method for storage and retrieval of energy includes storage of energy by performing electrolysis of water and directing the resulting hydrogen gas and oxygen gas to respective storage tanks. Energy is retrieved by directing hydrogen gas and oxygen gas from the storage tanks to a fuel cell where the hydrogen and oxygen are reacted to produce electricity and water. Water from the fuel cell is directed to a reservoir for subsequent electrolysis.
Claims7
A method for storage and retrieval of energy comprising the steps of:
- (a) storing energy by:
- (i) performing electrolysis of water within a electrolysis vessel such that the water decomposes into hydrogen gas and oxygen gas;
- (ii) directing the hydrogen gas through a first conduit and into a first storage vessel for storage therein;
- and
- (iii) directing the oxygen gas through a second conduit and into a second storage vessel for storage therein;
- (b) retrieving energy by:
- (i) directing said hydrogen gas from said first storage vessel along a third conduit into a fuel cell;
- (ii) directing said oxygen gas from said second storage vessel along a fourth conduit into said fuel cell;
- and
- (iii) reacting the hydrogen gas and oxygen gas within the fuel cell to produce electricity and water,
- and
- (c) directing water from said fuel cell to a reservoir for subsequent electrolysis as in step a), above,
- wherein the electrolysis vessel, first storage vessel, second storage vessel, fuel cell, and reservoir form a closed loop.

A system for storage and retrieval of energy comprising:
- a water reservoir;
- an electrolyzer in fluid communication with said water reservoir;
- a pump operable to draw water from said water reservoir and to direct said water into said electrolyzer;
- a first storage vessel in fluid communication with said electrolyzer and configured to receive oxygen gas therefrom;
