Integrated and Co-located Pumped Hydro Reverse Osmosis Systems

Project Overview

A.H. Slocum et al./Sustainable Energy Technologies and Assessments 18 (2016) 80-99. [[The integration and co-location of pumped hydro storage, hydro power and reverse osmosis desalinization plants optimizes efficiency and offsets capital investments, reoccurring operations and maintenance costs and reduces risk to investors. Low cost, excess renewable energy is used to pump seawater up to an elevated reservoir. When demand exceeds renewable power generation, the elevated seawater is fed to a hydro turbines at pressure to generate electrical power to the grid. A small portion of the pressurized water is concurrently routed to the reverse osmosis desalinization plant without the need for duplicative generators to produce freshwater. Finally, the brine residual produced during the desalinization process is mixed with the outflow of the hydro turbines, diluting the environmentally harmful solution before its return to the ocean.]]
