PNNL Researchers Test Storing CO2 Underground in Wallula

Posted: Updated:

WALLULA, Wash. - PNNL is conducting tests in Wallula to see if carbon dioxide can be stored underground in the Northwest, ultimately reducing carbon emissions.

Researchers based out of Richland are injecting liquid carbon dioxide half a mile below the surface to see if some of the carbon dioxide, blamed for global warming, can be locked up in underground basalt rock formations. 

PNNL says 1,000 tons will be pumped before the well is capped off and monitored for the next several months. Researchers say they hope the carbon dioxide will mineralize and never return to the atmosphere.

The Energy Department is funding most of the $12 million project.

Scientists are conducting the tests on property owned by the Boise paper mill on the Columbia River, about five miles downstream from the Tri-Cities.
