Grid Energy Storage

Our researchers are developing flow batteries to store renewable energy and support the power grid. Flow batteries produce power by pumping liquid from external tanks into the battery's stack, a central area where the liquids are mixed.

Renewable energy sources, such as wind and solar, have the potential to drastically reduce greenhouse gas emissions. However, wind and solar power are intermittent, presenting a challenge to utilities for predicting power availability and increasing the complexity of closely matched power supply and demand.

Large-scale energy storage is key to integrating renewable resources like wind and solar into the power grid, allowing us to use these resources when and where power is needed. Just a few years ago, there were essentially no large-scale energy storage deployments in Washington State. But the innovative researchers at PNNL have changed that. Today, large scale energy storage deployments in Washington State are in the double digits, creating a productive ecosystem of nationally recognized research, new company creation, and grid-scale deployment.

Our team of materials scientists, chemists, system engineers, and electrical and chemical engineers continue to solve challenges related to materials for large-scale storage batteries. We are also addressing technological and economic issues to assess the electric grid's ability to store renewable energy and bring these batteries to the broader marketplace.
