Along with researchers from three Idaho universities, geologists from Idaho National Laboratory (INL) in Idaho Falls will test how well the volcanic rocks abundant below the Columbia and Snake river plains store carbon dioxide. Researchers from INL, the University of Idaho, the Boise State University, the Idaho State University in Pocatello and the Battelle Pacific Northwest Division in Richland, Wash., are now making preparations to inject the gas into the subterranean volcanic basalt rock and monitor whether the rock can hold it.
