Direct Air Capture (DAC)

Direct Air Capture (DAC) is a technology for capturing low concentrations of CO₂ (ca. 400 ppm) from the air. As the captured CO₂ can be stored underground (Carbon Capture and Storage; CCS) or reused as feedstock for synthetic fuels or chemical products (Carbon Capture and Utilization; CCU), DAC technology is expected to contribute to carbon neutralization.

To be used for synthetic fuels and other applications, CO₂ must be captured with high purity and at low cost. The adsorbents used in the capture process must also resist degradation over time.
ENEOS was the first in the Asia-Pacific region to install a DAC unit from Climeworks, a global leader in DAC technology, and began demonstration tests in December 2023. The aim of these tests is to evaluate the performance of this technology in local environments, and to assess its applicability for large-scale deployment in the future.
