Thermoelectric Power Generation and Management Module

Hi-Z Technology, Inc. (Hi-Z) proposes to use its thermoelectric generators (TEGs) in developing a modular power generation and management system to supplement Littoral Combat Ship (LCS) mission system power services. The TEG will convert engine waste heat or heat from an auxiliary burner to electricity in a reliable and quiet mode. Hi-Z has developed TEG technology of converting waste heat from the existing power generators (diesel or gas turbine) and propulsion engines to electricity. In the engine exhaust, waste heat constitutes approximately 70% of the fuel energy consumed. Using the experience gained in developing and successfully testing a 1 kW(e) energy-harvesting TEG system on the exhaust of a diesel truck and in designing of a 10 kW(e) TEG system on Stryker engine exhaust during the current Army Phase II SBIR, Hi-Z plans to develop a conceptual design of a TEG capable of producing 50 kW(e). A power management system and energy storage unit will be designed to convert the TEG DC output to the required AC for convenient integration with the existing power system. The conceptual design will be based on Hi-Z innovative Quantum Well modules that are four times more efficient, leading to a more compact design.
