Abstract
Set forth herein are long duration energy storage systems that include at least two kinds of subsystems, one being a long duration subsystem such as, but not limited to, a reversible solid-oxide electrochemical fuel cell/electrolyzer and the other being a buffer system such as, but not limited to, a rechargeable lithium battery. Also set forth herein are processes of making and using these systems.
Claims95
An energy storage system (ESS), comprising:
- a long duration subsystem (LDS) configured for cross-charging with a buffer subsystem (BSS);
- and
- at least one processor for controlling series flow, parallel flow, charge C-rates, discharge C-rates, power electronics, or a combination thereof;
- wherein the ESS has a charge-to-discharge power ratio (c/d) of 1 to 10.
The ESS of any one of claims 1-13, wherein the LDS is coupled to a storage tank and configured to operate as at least one flow battery.
The ESS of any one of claims 10-16, wherein the LDS is configured to operate for 20-50 hours.
The ESS of any one of claims 1-20, wherein the LDS comprises at least one power component and at least one energy component.
The ESS of any one of claims 1-26, wherein the BSS comprises at least one electrochemical battery.
A method of using an energy storage system (ESS), comprising
- providing a long duration subsystem (LDS) configured for cross-charging with a buffer subsystem (BSS);
- and at least one processor for controlling series flow, parallel flow, charge C-rates, discharge C-rates, power electronics, or a combination thereof;
- inputting supply load data, demand load data, ancillary data, or a combination thereof into the at least one processor;
- and
- sending instructions from the at least one processor to the LDS, BSS, power electronics, or both, to charge or discharge the LDS, BSS, or both the LDS and BSS.
The method of claim 41, wherein the ESS is the ESS of any one of claims 1-43.
An energy storage network (ESN), comprising:
- at least two energy storage systems (ESS);
- and configured to:
- (a) transport charge media between the at least two ESS;
- (b) transport discharge media between the at least two ESS;
- or
- (c) a combination of (a) and (b).
The ESN of claim 55, wherein at least one ESS has a charge-to-discharge power ratio (c/d) of 1 to 10.
The ESN of any one of claims 51-55, further comprising at least one processor for controlling series flow, parallel flow, charge C-rates, discharge C-rates, power electronics, or a combination thereof;
The ESN of any one of claims 51-57, wherein the at least two ESS are linked via a roadway, railroad, shipping lane, or a combination thereof.
A method of using an energy storage system (ESS), comprising
- providing an ESN of any one of claims 54-97;
- and
- (a) transporting charge media between the at least two ESS;
- (b) transporting discharge media between the at least two ESS;
- or
- (c) a combination of (a) and (b).
