SwRI forms joint industry program to investigate safety, longevity of grid-connected energy storage systems

Green Car Congress

Southwest Research Institute (SwRI) has launched a new Joint Industry Program (JIP) to investigate energy storage systems for the grid. Over the course of its life, a grid-connected battery must respond slowly or suddenly, depending on the grid demands. One of the central questions is how long it takes for a battery to degrade.
