Supercapacitors are devices that harvest and produce energy from clean electrochemical or electro-kinetic mechanisms. Therefore, supercapacitors are gaining interest for applications where the entropy of mixing can be utilized to control energy storage and production. This analysis will cover the fundamental mechanism, practical design aspects, and performance calculations of membrane-modified supercapacitors. These supercapacitors are to be utilized in estuaries where the entropy of mixing is proportional to energy releases on the order of common hydroelectric devices. Membrane enhanced supercapacitors utilize the free energy from mixing fresh water with salt water and capacitive Donnan potentials (CDP) to store energy via electro-kinetics. Using membranes removes the auxiliary voltage requirement needed in current capacitive mixing modules and desalination devices. Therefore, this technology presents a more direct energy storage mechanism.Mechanical engineering, Energy conversion deviceANALYSIS AND PERFORMANCE METRICS OF A CAPACITIVE MIXING ENERGY CONVERSION DEVICEThesis
