Abstract
The invention provides a method of storing varying or intermittent electrical energy and one or more of hydrogen (H2) and oxygen (O2) with an energy apparatus, the method comprising: providing the first cell aqueous liquid, the second cell aqueous liquid, and electrical power from an external power source to the functional unit thereby providing an electrically charged functional battery unit and one or more of hydrogen (H2) and oxygen (O2) stored in said storage system, wherein during at least part of a charging time the functional unit is charged at a potential difference between the first cell electrode and the second cell electrode of more than 1.37 V.
Claims28
An energy apparatus, the energy apparatus comprising one or more functional units, each functional unit comprising:
- a first cell, comprising one or more first cell electrodes and one or more first cell openings for a first cell aqueous liquid and for a first cell gas;
- a second cell, comprising one or more second cell electrodes and one or more second cell openings for a second cell aqueous liquid and for a second cell gas;
- a separator, wherein the first cell and the second cell share the separator, wherein the separator is configured to block transport of one or more of O2 and H2 from one cell to another while having permeability for at least one or more of hydroxide ions (OH−) monovalent sodium (Na+), monovalent lithium (Li+) and monovalent potassium (K+);
- wherein the energy apparatus comprises one or more of (a) at least two or more first cell electrodes and (b) at least two or more second cell electrodes, wherein the energy apparatus further comprises an electrical element configured for applying one or more of (a) one or more potential differences between two or more first cell electrodes and (b) one or more potential differences between two or more second cell electrodes.
