Energy storage is slowly shifting utility planning practices from the current paradigm, which ensures grid reliability by building reserve generation resources, to ensuring grid reliability by optimizing grid services.

Researchers at PNNL used key metrics to develop visualizations that show how the combined effects of climate change on hydropower and load influence the frequency, duration, and severity of power shortfalls.

Plug and Play DER Challenge seeks to enable distributed energy technologies to integrate, connect and operate in harmony on the power grid.

When it comes to the special sauce of batteries, PNNL researchers say it's all about the salt concentration.

Nearly $6 million in new funding has been awarded to 15 energy storage projects through the PNNL-led Battery500 consortium.

PNNL research has created a unique video that shows oxygen bubbles inflating and later deflating inside a tiny lithium-air battery. The knowledge gained from the video could help make lithium-air batteries that are more compact, stable and
