If successful, the plant near Wallula, Walla Walla County, would be among the first power plants in the nation to curb its impact on the climate by keeping some of its carbon dioxide from floating into the atmosphere.
The use of thick volcanic rock known as basalt to trap the carbon could also have repercussions in places such as India — a country with extensive basalt fields, lots of coal and a growing appetite for electricity.
