Abstract: A thermochemical energy storage system and method of storing thermal energy are described. The energy storing system described herein comprises a reactor comprising: a) a reactor with a CO2 sorbent including MgO; and b) a supercritical CO2 source with supercritical CO2 and H2O, wherein the supercritical CO2 source is in fluid communication with the reactor and the CO2 sorbent including MgO to allow flow of the supercritical CO2 and H2O between the supercritical CO2 source and the reactor, thereby allowing contact of CO2 with the CO2 sorbent comprising MgO.

Abstract: Substantially pure water is produced via desalination using a directional solvent that directionally dissolves water but does not dissolve salt. The directional solvent is heated to dissolve water from the salt solution into the directional solvent. The remaining highly concentrated salt water is removed, and the solution of directional solvent and water is cooled to precipitate substantially pure water out of the solution.
