Abstract

Abstract A large source of energy exists at the interface between water bodies of different salinities. Two techniques, pressure-retarded osmosis and reverse electrodialysis, appear to be promising entrees into this energy source. Although the present cost of membranes suitable to these methods is too high, a research and development effort should make this salinity gradient energy competitive with other energy sources.
