Researchers 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 systems rely on complex plumbing to divert steam used to drive the turbines that generate power, and such systems are not practical as retrofits to existing plants. Now researchers have come up with a scrubbing system that requires no steam connection, can operate at lower temperatures, and can be added relatively easily to any existing power plant.
