Some of a growing number of industrial facilities equipped to capture carbon dioxide in the atmosphere that threatens human and environmental health are ramping up their carbon capturing capacities — and a new plant called “Mammoth” is many times larger than other such operations. Still, the capabilities of many plants fall short of what is needed to sufficiently decarbonize the atmosphere, says Klaus Lackner (pictured in an ASU photo), a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, and director of ASU’s Center for Negative Carbon Emissions. Lackner and other experts also express hope of finding ways to reduce the current high costs of decarbonization that remain a major hurdle.
