Proposed method could be more efficient than previous
systems and easier to retrofit in existing power plants.
Many researchers around the world are seeking ways to
“scrub” carbon dioxide (CO2) from the emissions of fossil-fuel power plants as
a way of curbing the gas that is considered most responsible for global climate
change. But most such systems rely on complex plumbing to divert the steam used
to drive the turbines that generate power in these plants, and such systems are
not practical as retrofits to existing plants
