Compact membrane-based thermochemical energy storage system

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 vapor channel positioned between the solution channel and the refrigerant channel;
• a first fluid channel having a heat source/heat sink fluid flowing therethrough;
• a second fluid channel having a heat source/heat sink transfer fluid flowing therethrough;
• a first porous membrane positioned between the refrigerant channel and the vapor channel;
• a second porous membrane positioned between the vapor 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 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.
