Project title: Solar Redox Flow Batteries

Main supervisor: Dr. Anders Bentien

Project period: November 2015 to November 2018 

Project description
Solar power as a clean and economical energy source plays an important role in the 21st century in a low greenhouse gas future. This most environmentally friendly intermittent energy source (solar) constitutes yet a small fraction compared to hydropower. Globally, solar installed capacities are growing at rates of 60% driven by the necessity to reduce carbon emissions.

On the other hand, large-scale energy storage serves as an important means to enhance the efficiency and power quality of the electrical grid. In order to do this, Redox flow batteries (RFBs) or Redox Flow Cells (RFCs), are considered as they meet many of requirements such as modular

design, fast response time, durability for large numbers of charge/discharge cycles as well as calendar life, high round-trip efficiency, an ability to respond rapidly to changes in load or input, and reasonable capital costs. In redox flow batteries (RFBs) at least one electrode comprises a solution (or sometimes movable slurry) of an electroactive material, and energy is generated/stored when the redox species flow through the electrochemical cell. Anode and cathode chambers separated by an ion-exchange (cation or anion) or microporous membrane and undergo electron transfer reactions at inert electrodes.

This project is focused on finding of suitable redox couples, electrodes and membrane in order to have a low cost and efficient solar flow battery.
