Energy storage technologies such as batteries, flywheels and thermal storage are poised to reshape our energy systems at the scales of the grid, communities, buildings and vehicles, and the relationships between these categories.  This first of two sessions will provide an overview of energy storage technologies, applications and markets in the Northeast region and nationally. It will highlight the research from the Massachusetts Department of Energy Resources energy storage study underway.  Is the energy storage tipping point truly in sight?  What market applications are favorable for which sets of technologies? What impact will storage have on renewable energy deployment? How might electric vehicles mobilize opportunities for energy storage in the built environment? Please join us as we cut through the hype for a lively discussion of developments in this dynamic field.
