Abstract

We are on the verge of a major transformation in the electricity infrastructure over the next ten to twenty years. This is driven by the need to modernize an aging electric grid and rapid integration of distributed generation on a large scale. As we transition towards a greater role for renewables and distributed generation in the electric grid, addressing intermittency and providing grid operators flexible assets to efficiently manage the grid is becoming critical. Large scale integration of energy storage is essential to manage the future grid, and we are beginning  to integrate energy storage into the grid infrastructure at a scale we have not considered until now. In this presentation, I will first present trends in grid modernization and discuss gaps in technology and implementation of energy storage in the grid infrastructure. This will be followed by review of current work at Sandia in grid modernization and energy storage highlighting current work in flow batteries, sodium batteries, zinc batteries, membranes, power electronics and power converters, energy storage safety, microgrids, grid modeling and integration.

I will also touch upon the summer internships, post-doctoral research, and regular employment opportunities at Sandia.
