Patent number: 9853454Abstract: A redox battery energy storage system including multiple energy storage stacks having multiple reactor cells is disclosed. Each of the energy storage stacks may include an integrated DC/DC converter configured to convert an output voltage of the stacks to a higher output voltage. The output of the DC/DC converts may be coupled in parallel to an energy storage system output bus. By configuring the energy storage system in this manner, inefficiencies and losses caused by shunt electrical currents in the systems may be decreased.Type: GrantFiled: December 20, 2011Date of Patent: December 26, 2017Assignee: JD Holding Inc.Inventor: Timothy David John Hennessy

Patent number: 7740977Abstract: A vanadium redox battery energy storage system (“VRB-ESS”) capable of modularly incorporating additional electrolyte reservoirs to increase energy capacity while allowing for efficient low-volume operation is disclosed. The VRB-ESS of the present invention may efficiently operate using a first volume of electrolyte solution, while maintaining a second volume of electrolyte solution to be made available to the VRB-ESS as additional energy storage capacity is required. Additionally, a cap mechanism to allow the VRB-ESS of the present invention to employ an industry standard IBC container as a secondary electrolyte reservoir is disclosed.Type: GrantFiled: March 26, 2007Date of Patent: June 22, 2010Assignee: JD Holding Inc.Inventors: Gary Lepp, Matthew Albert MacLennan Harper, Andy Klassen, Timothy David John Hennessy

Patent number: 7517608Abstract: An improved redox battery energy storage system is disclosed for reducing oxygen gas levels and separating oxygen gas from hydrogen gas, thus reducing the likelihood of flammable gas explosions. The system includes at least one cell, which includes a positive compartment having positive solution, a negative compartment having negative solution, and a membrane separating the positive and negative compartments. A positive reservoir is in fluid communication with the cell's positive compartment, the positive reservoir defining a positive vent space for positive gas, which includes oxygen. A negative reservoir is in fluid communication with the cell's negative compartment, the negative reservoir defining a negative vent space. A return line is in fluid communication with the negative compartment and the negative reservoir to return the negative solution from the cell to the negative reservoir through the negative vent space.Type: GrantFiled: March 9, 2007Date of Patent: April 14, 2009Assignee: VRB Power Systems Inc.Inventors: Clive Brereton, David Genders, Gary Lepp, Timothy David John Hennessy

System and method for a self-healing grid using demand side management techniques and energy storage
Patent number: 7389189Abstract: A self-healing power grid control system includes a power grid having a plurality of network islands with a plurality of linear and non-linear loads. A plurality of control sensors communicate with the power grid to monitor the electrical characteristics of the power grid. A plurality of controlled relays are in electrical communication with the plurality of non-linear loads. A battery energy storage system (ESS) is in electrical communication with a main power source and a network island. A first restoration controller is in electrical communication with the control sensors, the controlled relays, and with the battery ESS. The first restoration controller receives control signals from the control sensors, and in response to detecting an irregularity in the power grid, automatically actuates the battery ESS to stabilize power to the linear loads, and disconnects selected controlled relays to disconnect power to a calculated percentage of the non-linear loads.Type: GrantFiled: October 23, 2006Date of Patent: June 17, 2008Assignee: VRB Power Systems Inc.Inventors: Bradley R.
