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

Algae can collect and concentrate rare earth metals from seawater—an alternative to imported sources mined from the ground.

From energy-efficient buildings to new manufacturing techniques, researchers at PNNL strive for sustainability and a decarbonization.

PNNL is making waves in pursuit of a blue economy. Researchers are advancing science and technology to expand—and protect—the gifts of the sea.

COMPASS points to understanding nature’s transition zones—areas that can be dry land at times and under water at others.

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.

Understanding the Earth as a complex, dynamic system includes investigating what happens on, above and below its surface.

Alaska's remote location and vast wilderness contribute both to its beauty and its challenges.

Discovery in action. These words describe what we do at PNNL. For more than 50 years, we have advanced the frontiers of science and engineering in the service of our nation and the the world.

Led by Battelle in collaboration with the Bonneville Power Administration, the Pacific Northwest Smart Grid Demonstration Project is the largest field test of smart grid systems to date.
