Publication number: 20230086892Abstract: Various embodiments include a thermal storage system for storing energy in a graphite thermal storage structure and a thermal shutter assembly configured to control the transmission of heat from the graphite thermal storage structure to a thermal energy receiver, such as a heat exchanger or material processing crucible. A thermal storage block, which may be made of graphite, may be isolated by insulation except for the thermal shutter assembly. Energy may be stored in the graphite thermal storage block by applying energy to the block to raise its temperature to maximum operation temperature. Stored energy may then be harvested in a controlled manner by a control system actuating the thermal shutter to expose the thermal energy receiver to thermal radiation.Type: ApplicationFiled: August 31, 2022Publication date: March 23, 2023Inventors: Andrew Cameron ROBERTSON, Harold Edwin DITTMER, Gary Alan FRANZEN, Timothy Michael MANN

Patent number: 10742038Abstract: Various embodiments include an energy storage system for a hybrid energy system including a an energy storage device configured coupled to an inverter and controlled by a hybrid management system. The hybrid management system may be configured to use energy from the energy storage device to supplement power output of a power generation system to comply with a contract schedule of electric power output by the hybrid energy system. The hybrid management system may be configured to satisfy stable loads of an industrial application with the power generation system and to meet load swings of the industrial application with power output from the storage device. The hybrid management system may be configured to respond to an increasing desired load transient event by disclosing stored energy to follows a ramping profile that substantially matches a gas-turbine alone ramp rate of a gas turbine generator operating in a spinning reserve mode.Type: GrantFiled: November 25, 2019Date of Patent: August 11, 2020Assignee: Wellhead Power Solutions, LLCInventors: John Grant McDaniel, Harold Edwin Dittmer
