A research group of six institutions, including Tokyo Metropolitan University and Taikisha, has embarked on a project to develop a "DAC (Direct Air Capture) System" that enables the capture of large amounts of carbon dioxide (CO2) from the atmosphere. We will develop a "passive DAC" that utilizes natural wind and wind generated while driving, without using the air blowing power that has been a bottleneck in DAC technology to date. We will build and demonstrate a new low-power system capable of capturing large amounts of CO2.

The research team consists of six parties: Tokyo Metropolitan University, Taikisha Publishing House, Pantalei, Nagaoka University of Technology, Kojima Printing Company, and Kyushu University. The development project has been selected for the public program "Moonshot Research and Development Project: Achieving Sustainable Resource Circulation for Regenerating the Global Environment by 2050" of the New Energy and Industrial Technology Development Organization (NEDO). The total cost of the project is approximately 1.9 billion yen. The project will last until fiscal year 2017.
To achieve these goals, the team will work on: developing a stationary passive DAC system; establishing a mobile passive DAC system; and developing a microwave-based CO2 capture and desorption system. We will establish a technology that uses wind power generated by trucks, boats, and other vehicles to capture and absorb CO2 from the atmosphere without any power source. We will also develop a CO2 capture and desorption system by directly heating solid carbamic acid generated by passive DAC with energy-efficient microwaves.
The plan is to capture 1.2 tonnes of CO2 from the air each year by fiscal 2017 and limit energy consumption per tonne of CO2 to below 4.5 gigajoules. In the future, the goal is to combine this with technology to convert captured CO2 into useful hydrocarbons, and by 2050, capture 150 million tonnes of CO2, store 50 million tonnes and turn 100 million tonnes into resources, thereby creating a carbon-neutral society.
