New climate deal spurs hopes of more carbon storage projects
GILLETTE, Wyo. (AP) — The rolling prairie lands of northeastern Wyoming have been a paradise of lush, knee-deep grass for sheep, cattle and pronghorn antelope this summer.
But it’s a different green — greener energy — that geologist Fred McLaughlin seeks as he drills nearly two miles (3.2 kilometers) into the ground, far deeper than the thick coal seams that make this the top coal-mining region in the United States. McLaughlin and his University of Wyoming colleagues are studying whether tiny spaces in rock deep underground can permanently store vast volumes of greenhouse gas emitted by a coal-fired power plant.
This is the concept known as carbon storage, long touted as an answer to global warming that preserves the energy industry’s burning of fossil fuels to generate electricity.
So far, removing carbon dioxide from power plant smokestacks and pumping it underground hasn’t been feasible without higher electricity bills to cover the technique’s huge costs. But with a $2.5 billion infusion from Congress last year and now bigger tax incentives through the Inflation Reduction Act passed by Congress on Friday, researchers and industry continue to try.

The federal government is investing heavily in the development of carbon capture and storage (or sequestration), which offers the enticing prospect of preventing carbon dioxide emissions produced during combustion from entering the atmosphere and contributing to climate change. But the technologies involved, while proven, remain expensive, an obstacle to widespread adoption.
