A method and apparatus for renewable power generation utilizes the chemical potential dissimilarity between solutions of differing ionic formulations. A train is formed by a sequentially ordered set of a plurality of cells in which each successive cell is related to the preceding cell. Each cell has pumping means and hydro-power generation turbine means to form a closed hydraulic loop configured for specified volumetric and flow capacity. Adjacent cells share semipermeable membranes. Each cell is charged with a brine of specified ionizable inorganic salt quantity and type with the brine being cycled in a controlled concentration-pressure loop, with each of the cells operating at progressively increasing concentration and osmotic pressure ratio.
