An innovative long-term energy storage system will be built in the USA

Pacific Northwest National Laboratory (PNNL) and technology provider Invinity Energy Systems have initiated a project to construct and test a vanadium redox flow battery capable of 24-hour discharge.

At the PNNL Richland campus in Washington State, USA, a vanadium redox flow battery (VRFB) will be installed with a capacity of 525 kW. This system will sustain continuous power release over 24 hours, providing a total energy storage capacity of 12.6 MWh.

A promising start to the journey

Leveraging prior research in VRFB technology, PNNL aims to assess the project’s technical performance, crucial in fortifying campus energy resilience. Vincent Sprenkle, an energy storage expert at PNNL, highlighted how this endeavor will advance the broader adoption of long-term energy storage (LDES) for commercial use.

This initiative has been made feasible through a $10 million grant from the Office of Clean Energy Demonstration (OCED) within the United States Department of Energy (DOE). VRFB technology stands as a commercially mature option for long-term energy storage, offering an alternative to lithium-ion technologies.
