摘要： Disclosed are high enthalpy thermochemical energy storage materials that exhibit high thermal conductivity and stability at high temperature reaction conditions. Disclosed materials include hydride-based alloys that can undergo high temperature reversible hydrogenation/dehydrogenation reactions without phase change of any metal or metalloid components of the alloy. The materials undergo a reversible exothermic hydrogenation reaction to form a metal hydride and a ternary alloy that includes a high thermal conductivity metal that, in its pure state, would exhibit a phase change at the hydrogenation reaction conditions.

摘要： The present invention discloses a heat exchanger system for thermochemical storage and release. The system comprises a thermal exchange circuit with a heat exchanger fluid, the circuit further in thermal connection with a thermochemical module. The thermochemical module comprises a thermochemical material that stores and releases heat by a thermochemical exchange process under release or binding of a sorbate. The thermochemical module comprises a compartment structure that compartments the thermochemical material and further comprises a channel structure. This provides an exchange of the sorbate and the thermochemical material via the channel structure to the compartment structure. A method for the preparation of the compartment structure is also described. In this method, the thermochemical material is brought in a liquid phase and inserted in the compartment structure, while keeping the channel structure free from the liquid phase; and subsequently dried.

摘要： A system and method for providing dry cooling of a source liquid, having a plurality of heat exchangers which depolymerize and polymerize a polymer. Specifically, the depolymerization process is endothermic and draws heat from a source liquid in a first heat exchanger, and the polymerization process is exothermic and expels heat from a second heat exchanger. Additional heat exchangers and holding tanks may be incorporated in the system and method. In some embodiments the system further provides additional cooling of the polymer prior to depolymerization using cooler night ambient air.

摘要： Ammonium carbamate-based methods and systems for management of thermal loads, particularly low-quality, high-flux thermal loads. The increase in temperature in heat sensitive devices is mitigated by the endothermic decomposition of ammonium carbamate into carbon dioxide and ammonia gases. This process has an energy density an order of magnitude greater than conventional thermal management materials and is particularly useful for temperatures between 20° C. and 100° C. Systems incorporating ammonium carbamate may be controlled by regulating the fluid flow, overhead pressure, temperature, or combinations thereof.
