The successful integration of renewable energy sources into the energy grid will likely depend on the development of suitable electrochemical energy storage (EES) systems. These EES systems must be able to efficiently store electricity during peak generation and then release it within the required timeframe during peak demand. The battery systems must be reliable, durable, safe, and affordable in order to facilitate widespread deployment of renewable energy in most parts of the country. For the past several years, Pacific Northwest National Laboratory (PNNL) has conducted extensive research and development efforts in energy storage systems suitable for stationary energy storage and grid support applications under funding from the Department of Energy – Office of Electricity (DOE-OE. This talk will provide an overview of PNNL’s OE funded development efforts including redox flow, Na-metal, Li-ion, Na-ion batteries as well as our cost modeling and grid analytics efforts.
