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. A continuous and constant flow rate of substantially salt-free permeate flux is maintained across each cell, the flux being osmotically induced from low salt concentration water being fed at the first cell in the train and exiting at the last cell along with the discarded high concentration water brine. The salt-free permeate flux is continuously induced, in symbiotic mode, through the shared membranes, driven by the chemical influence of concentration potential field bounded by water of low to no salt concentration on one end of the train and by brine of high salt concentration on the other end of the train with sufficient concentration difference to provide driving force for said plurality of cells, while maintaining adequate concentration difference between adjacent cells to enhance osmosis function, as well as defining a concentration ratio within each cell to ensure a net positive power generation.
