Because of global warming, there are a lot of proposals about ways to reduce carbon dioxide. But one practical idea may be to simply pump the CO2 back into the ground where it came from. Indeed, according to the San Francisco Chronicle, just such a test site is being developed at Teapot Dome in Central Wyoming. Teapot Dome is famous for a major oil lease scandal in the 1920’s, but now, researchers believe it could hold at least 1.6 million tons of CO2 per year for up to 10 years. The gas would be injected as liquid into the reservoir through a pipeline, and since it could remain sealed there for thousands of years, that should be good news for those all heated up about global warming.
