Days after SustainX’s announcement of a new compressed air energy storage (CAES) project comes the news that another site is being considered for a more conventional form of the technology. A layer of porous rock below the Yakima River Canyon could be ideal for storing the vast quantities of compressed gas needed, reports the Yakima Herald.

Researchers from the Bonneville Power Administration and the Pacific Northwest National Laboratory think the site could be the ideal place to store enough energy to power up to 110,000 homes, says the paper. If the project receives the funding needed, Yakima will be only the third such site in the world.
