Future holiday homecomings could include efficient heat pumps in cold climates and homes designed and built with the environment in mind.

PNNL researchers are helping to better define the need for grid energy storage in future clean energy scenarios, as well as working to improve technologies for storing renewable energy so it's available when and where it's needed.

PNNL and industry developing a faster, less expensive way to extract lithium for batteries used in cell phones and electric vehicles.

Recognizing how innovation and clean technologies at the very edge of the grid can work together to transition the electricity system, PNNL takes a multidisciplinary approach to advancing and integrating renewable energy solutions.

PNNL’s new Energy Sciences Center has capabilities for scientists to advance solutions for storing clean hydrogen in chemical bonds.

Researchers developed two solutions for air-conditioning—a novel, energy-efficient dehumidification system and a technology to detect refrigerant leaks. Both help increase energy-efficiency and reduce costs.

Despite the challenges, the talented and dedicated staff at Pacific Northwest National Laboratory kept delivering for the nation.
