Abstract: A thermal energy storage device may include a heat storage medium, one or more thermosyphons, a discharging plenum chamber, and a discharging plenum chamber. The one or more thermosyphons may include an evaporative section configured to charge the thermal energy storage device, a condensing section configured to discharge the thermal energy storage device, and a heat transfer section extending between the evaporative section and the condensing section and fluidically coupled to the evaporative section and the condensing section. At least a portion of the heat transfer section may be disposed in the solid heat storage medium. At least a portion of the evaporative section and the condensing section may be disposed outside the solid heat storage medium.

Abstract: Concrete materials and thermal energy storage devices employing such concrete materials are disclosed herein. The concrete material may include fibers in an amount ranging from about 1 to about 2 vol. %; an aggregate in an amount ranging from about 50 to about 80 vol. %, wherein the aggregates comprises siliceous aggregate and optionally carbonate aggregate; and a cementitious material in an amount from about 12 to about 20 vol. %, wherein the cementitious material comprises a combination of about 70 to about 85 vol. % of Portland cement and about 15 to about vol. % of silica fume, wherein all volume percentages unless otherwise indicated are based on the total volume of the concrete material.
