Abstract: As the demand for renewable energy increases, there is a need for storing energy for later use. Vanadium Redox Flow Battery (VRFB) was identified as the energy storage system for the project, and porous ion selective membranes are being explored as Nafion, a commercial ion exchange membrane usually used for its high conductivity and chemical stability, is expensive due to the dangerous production process. In this project, we investigated three commercial pH-stable nanofiltration (NF) membranes (Microdyn-Nadir NP010, Microdyn-Nadir NP030, and Suez Duracid). The project studied the selectivity and stability of the porous ion selective membranes to evaluate the feasibility of their usage in the VRFB application, explored modification methods to improve the selectivity of the membranes, and researched on the charge-discharge cycles of the VRFB at different current densities. Lastly, due to time constraints, recommendations for future research were also discussed.
