Chapter 1 INTRODUCTION AND BACKGROUND Due to the increasing demand for clean energy and improving efficiency of such technologies, the adoption of renewable energy sources is on the rise. Energy sources such as wind and solar are already capable of supplying a large fraction of the required energy in many electrical grids. However, there is a major problem with these sources known as intermittence [1]. The amount of power produced is not constant (e.g. solar) and the variation in supply can be unpredictable (e.g. wind). In either case, supply does not match demand and at times there will either be too much energy or a lack of energy in the grid. If intermittent sources contribute to a small portion of a grid’s supply, these variations in supply can be offset by controlling the output of traditional sources. However, if intermittent sources are responsible for more than 10-20% of a grid’s total energy output, destabilization can occur [1]. For a renewables-dominated grid to be both reliable and efficient, a grid-scale energy storage solution must be adopted. 1.1 Operating Principles A redox flow battery is an electrochemical device used to store and dispense energy. These rechargeable batteries convert electrical energy to chemical energy (and vice versa) through the reduction and oxidation of two ionic species which are dis- solved in electrolytes. This electrochemical process is visualized in figure 1.1. During discharge, a load is placed across the anode and cathode. The anolyte (negatively charged electrolyte) and catholyte (positively charged electrolyte) are pumped through half cells separated by an ion exchange membrane. The porous anode draws electrons off of the active ions in the anolyte and these electrons travel through the external 1PDF Image | PERFORMANCE EVALUATION OF A REDOX FLOW BATTERY
