Embodiments of the present invention provide, by way of example, high-ratio latent thermal energy storage and recovery devices, the devices comprising a reservoir for containing a phase change material, a cover , a plurality of heating elements, at least one heat conducting element and an inert gas system. The tank walls and covers of the device are laminated in three layers comprising a low thermal conductivity carbon fiber composite inner layer, an intermediate insulation layer and an outer layer of high strength material such as carbon fiber fiber. glass. The use of CFC transforms the device into a high-ratio latent energy device. The reservoirs comprise hollow protrusions for the insertion of the thermoconductive elements. The projection has an opening at its distal end for contacting the thermally conductive elements with suitable devices such as heat engines that can utilize thermal energy stored for other purposes. |
