1. A thermochemical energy storage system comprising:
a membrane-based thermochemical reactor including:
a solution channel having an absorbent-containing solution flowing therethrough;
a refrigerant channel having a refrigerant flowing therethrough;
a first fluid channel having a thermal transfer fluid flowing therethrough;
a second fluid channel having a heat source/heat sink fluid flowing therethrough;
a porous membrane positioned between the refrigerant channel and the solution channel, the porous membrane permitting flow of vapor molecules therethrough while restricting flow of absorbent molecules;
wherein the first fluid channel is positioned next to the refrigerant channel, separated by a channel wall, and the second fluid channel is positioned next to the solution channel;
a solution storage repository for storing the absorbent-containing solution in fluid communication with the solution channel; and
a refrigerant repository for storing the refrigerant in fluid communication with the refrigerant channel.
