Energy Storage

In a survey conducted among IERE members in May 2019, energy storage was selected as the next candidate for in-depth research following TF2017, after artificial intelligence, which had already been launched. IERE then decided to take this further by initiating it as a direct collaborative research project.

Battery Energy Storage (Leader: SwRI)

The objectives are to develop a battery degradation model under “composite grid duty”—a mix of real-world operational modes such as charge/discharge cycling, peak shaving, and frequency regulation—and to assess the associated risks of battery fire and explosion. Project Details
