Development of Technology for Extracting CO2 Directly from the Atmosphere = Direct Air Capture (DAC)
Overview
For the time being, capturing and utilizing CO2, the raw material for e-methane, is expected to occur in the industrial sector, but in the future, it is possible that the importance of CO2 derived from biomass or directly captured from the atmosphere, which are more environmentally friendly, may increase. We are currently working on research and development into how to extract CO2 from the atmosphere, using our core material technology.

Development of Adsorbent for DAC
To realize energy-efficient DAC, we are working on developing high-performance DAC adsorbents that have both a high CO2 adsorption capacity and low-temperature CO2 desorption properties.

Demonstration Using a Laboratory Machine
We have created a test machine and confirmed that it is possible to capture high concentrations of CO2 from the atmosphere (CO2 capture concentration: 99 vol% or more).

Future Prospects
Going forward, we will continue to work on further improving the performance of adsorbents and establish DAC technology, helping create a carbon-neutral society.
