University Team Developing Novel Low-Cost Energy Storage System

Two Cal Poly Pomona engineering professors have won a $149,000 grant from the U.S. Bureau of Reclamation to continue development of a low-cost energy storage system using reverse osmosis concentrate (ROC), the byproduct of water desalinization plants. As droughts increase, more communities, especially in the Southwest U.S., are considering desalinization plants to meet their fresh water needs. However, ROC is harmful to the environment due to its high salt content, biocides, metals and coagulents. At the same time, the energy sector is looking for more cost-effective methods of energy storage.
