This disclosure provides a system for coupling supercritical carbon dioxide cycle power generation and lithium extraction from brine. The system comprises an absorption heat pump unit, a supercritical carbon dioxide cycle power generation unit, and a unit for extracting lithium from brine. This system organically couples the exothermic characteristics of the supercritical carbon dioxide cycle system with the endothermic characteristics of the lithium extraction from brine system, and the waste heat is recycled in a cascade as the heat source in the lithium extraction from brine system, thereby effectively reducing the total energy consumption of power generation and lithium extraction and reduce the total equipment investment of the system, and significantly improving the efficiency of adsorption and lithium precipitation in the lithium extraction from brine system.

The invention provides a heat pump system and method comprising a Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) core (2a, 2b) positioned in a housing and adapted to absorb heat and store energy in response to a first fluid inputted at a first temperature. The housing is configured to receive a second fluid via an inlet wherein a device changes pressure in the housing to cause the SMA or NTE core to change state to release the heat absorbed into the second fluid. An outlet is adapted to output the second fluid at a higher temperature than the first temperature.

Disclosed is an adsorption-based heat pump useful for refrigeration and cooling/heating for applications such as HVACs and chillers. Adsorption is a surface phenomenon where a solid substance (adsorbent) attracts molecules of a gas or solution (refrigerant or adsorbate) on its surface. The latent heat of the adsorbate provides the heating/cooling effect. The novel adsorption heat pump enhances heat and/or mass transfer to and from the adsorbate. One embodiment comprises at least one evaporator, at least one desorber (adsorbent heating apparatus), at least one adsorbent cooling apparatus and at least one condenser. The embodiment employs different techniques to enhance heat and/or mass transfer.
