    TEGS Prototype

    Our thermal energy grid storage (TEGS) system combines a unique type of power conversion device called a multi-junction thermophotovoltaic (TPV) heat engine with a pumped liquid metal loop. We are currently building and testing a prototype system in the lab. The system shown here was built to test the heat to electricity conversion components of the technology. It is composed of a graphite cavity heated by a graphite heater and surrounded with graphite insulation. A heat sink can be actuated into the cavity for TPV testing.
