ROAD VEHICLE THERMAL ENERGY STORAGE CONCEPT AND EVALUATION: PHASE I. FINAL REPORT, JANUARY--OCTOBER 1978

A conceptual design has been developed for a thermal energy storage system that will adequately power a Stirling engine for highway vehicle propulsion. A lithium magnesium fluoride eutectic with a melting point of 741 exp 0 C is used to store 102.4 kWh of energy over the temperature range of 600 to 825 exp 0 C. A two-phase liquid metal (potassium) is required to attain the heat transfer rates. A cobalt-containing alloy (Inconel 617) provides adequate creep rupture strength at operating temperatures for the 10-year design life. The present concept includes recharge by electric resistance heating. The system design was developed within the specified size and weight restraints of 0.4 m exp 3 and 500 kg, respectively.
