Abstract

A pressure retarded osmosis (PRO) method and system, and systems integrating the PRO system for osmotic energy harvesting and storage, are disclosed herein. The PRO system is configurable as a semi-closed PRO system. The PRO system may be part of an integrated multi-functional desalination-osmotic energy storage (DOES) system. The system may be further configured to switch between any of a semi-closed PRO mode, a closed-loop PRO mode, a closed-circuit PRO mode, a semi-closed reverse osmosis (RO) mode, a closed-circuit RO mode, and a closed-loop RO mode.
