Instead of CO 2 , this technology produces water, which in turn is reused in the integrated process. They are used in a direct reduction plant in Siemens compressors.
Most climate models have suggested that evapotranspiration, which is the movement of water from the land to the atmosphere, would increase with global warming because of increased evaporation of water from the ocean and more precipitation overall. Data indeed show that some areas are wetter than they used to be. —Jung et al.
