Further technicalĪpproaches are under development, e.g. If exposed to high humidity or if wetted directly. In Arizona developed a synthetic membrane that absorbs CO 2įrom dry ambient air. Several firms captureĪmbient air by using large fans to push air through the filters, Swiss Climeworks AGĪ method of bubbling air through a liquid sorbent the CO 2Īir through the filter requires energy as well. Once the filter is saturated,Ĭan be isolated by applying heat. Multiple uses of the filter orĪbsorbent are possible in most cases. Is using a strong hydroxide solution as a chemical absorbent. Synthetic fuels, enhanced oil recovery, mechanical trees, and aįrom ambient air involve a filter or absorbent. Impacts or the likelihood that it will actually reduce overall carbonĮmissions, several companies have already started marketing DACĪs a climate solution, and propose capturing CO 2Īs a feedstock for industrial uses. Little is known about the technology’s efficiency, safety, economic During the past two decades, the technology – known as Direct Air Capture (DAC) – has been further developed, but in a different context: researchers are considering the technology as a means to remove CO 2 or other greenhouse gases from the earth’s atmosphere. In the early 1990s, the European Space Agency launched a technology to extend space missions by filtering exhaled CO 2 out of the air on board of shuttles and space stations.
