Abstract

Salinity gradient energy (SGE) is the physico-chemical energy released from an aqueous solution when freshwater is mixed with salt water. SGE is expected to be an alternative energy source that is not affected by weather or time of day, especially near estuaries, where large amounts of water can be taken from rivers and the sea. In this study, we theoretically evaluated the SGE potential and electric power available in 109 major rivers in Japan to identify suitable locations for SGE applications. Furthermore, we examined the usefulness of SGE by comparing the amount of electric power extractable from SGE to that obtained from other power generation methods.
