Symposium EE8-Grid-Scale Energy Storage

Energy storage at the scale of a power grid is a difficult but important challenge. It is also a contemporary problem, brought on by the shift to alternative energy sources that are dependent on season, weather, and day-night cycles which has been spurred on by the availability of low-cost photovoltaics. Additionally, grid-scale energy storage is essential in remote areas that have limited grid connectivity or sole-source power production. These isolated locations include islands and scientific and military outposts. Balancing the grid at the utility and consumer is desirable, and therefore, a large toolkit of storage options are needed to address specific grid architectures.

A wide array of systems level and materials challenges still must be addressed in grid scale energy storage. Chemistry and materials science are continually developing next generation systems that improve upon previous iterations. Integration and power management systems tailored to each new storage technology must then be built and implemented.

This symposium will highlight the latest, and highest impact, advances in grid storage technology at all scales and stages of development to generate a top-level view of the field. Specifically discussed in this symposium will be new advances that address safety issues through materials, low-cost redox-active materials for electrolytes, new electrode materials and architectures, large-scale variants of nonstandard storage systems, systems integration, advanced models for lifecycle analysis, and cost-benefit analyses for storage systems.
