This paper provides an overview of flow technologies and how the ESRC’s research and test center of excellence supports the evaluation and validation of various grid-scale flow battery technologies, with systematic characterization and evaluation including: factory acceptance testing, baseline functional and performance characterization, and advanced testing and modeling, including stacked services testing also informed by the duty cycle tests developed by Sandia and Pacific Northwest National Laboratories The ESRC includes a software-hardware infrastructure that enables economic evaluation as well as support modeling of aging and performance over time for a range of technologies. A Factory Acceptance Test (FAT) has been done on an Avalon Flow battery system: 1. Visual inspection of all system components 2. Basic DC testing of 3 of 9 of the batteries 3. AC testing of a 3 battery string 4. Post-DC and AC testing visual inspection
