Abstract: Disclosed herein is a method and apparatus that uses a brine from a well that is used to both generate electricity and recover valuable minerals present in the brine. The method and apparatus uses a hydrophobic membrane to separate water vapor from the brine to concentrate the brine that is then used to recover the minerals.

Abstract: A system for thermally servicing a solvent-refining column includes: a first solvent-refining column, a closed-loop water-steam system; a first heat-exchanger thermally coupling the closed-loop water-steam system to the top of the first solvent-refining column, a second heat-exchanger thermally coupling the closed-loop water-steam system to a bottom of the first solvent-refining column, and a compressor positioned between the first heat-exchanger and the second heat-exchanger. The first heat-exchanger boils pressurized water to steam by transferring first heat from the top of the first solvent-refining column to the closed-loop water- steam system. The compressor compresses the steam in the closed-loop water-steam system to a higher temperature. The second heat-exchanger provides second heat to the first solvent-refining column by condensing the steam at the bottom of the first solvent-refining column after compression by the compressor.

Abstract: A method of manufacturing a cathode material for a lithium ion cell comprises: generating a lithium nickel composite oxide material in a manufacturing process, wherein the manufacturing process results in residual lithium being present in the lithium nickel composite oxide material; washing the lithium nickel composite oxide material to remove at least part of the residual lithium, wherein the washing provides the lithium nickel composite oxide material with a moisture content; and drying the lithium nickel composite oxide material to remove at least part of the moisture content, the drying performed in an environment of substantially only an inert gas or air essentially free of carbon dioxide.

Abstract: A thermochemical energy storage system and method of storing thermal energy are disclosed. The energy storing system described herein comprises a reactor comprising a CO2 sorbent comprising i) CaO and mayenite or ii) Li4SiO4, or a combination thereof, and b) a CO2 source, wherein the CO2 source is in fluid communication with the reactor to allow flow of CO2 between the CO2 source and the reactor. Further, methods are disclosed for storing thermal energy through a wide temperature range.
