Study finds a natural impediment to the long-term
sequestration of carbon dioxide.
Carbon sequestration promises to address greenhouse-gas
emissions by capturing carbon dioxide from the atmosphere and injecting it deep
below the Earth’s surface, where it would permanently solidify into rock. The
U.S. Environmental Protection Agency estimates that current
carbon-sequestration technologies may eliminate up to 90 percent of carbon
dioxide emissions from coal-fired power plants.
