Patent ID: 11092141

Abstract:
Method and apparatus are disclosed for maximizing the generation of large-scale renewable energy (LSRE) by pressure-enhanced osmosis (PEO) and synergistic effects, in which a PEO module is designed by increasing the maximum power generation by increase of the dilution factor β to enhance a power output beyond ten times of the conventional PRO method, and even more power can be generated by the PEO method by incorporation with synergistic effects to form two types of PEO systems: (1) a surficial PEO system, in which the synergistic effects are achieved through combined effects of FO and nanofiltration (NF) or ultrafiltration (UF), and application of an energy exchange and fluid recovery device for re-concentration and reuse of the draw solution, (2) a subsurface PEO system, synergistic effects are achieved through application of the gravitational potential, application of waste heat from power generation, and application of an uplift chamber.
