The CO2 capture and storage technology (CCS technology) needs immediate action, but does not have complete solutions yet due to the lack of efficient and economical CO2 conversion ideas. The governing fundamental quantities will be identified to obtain the maximum energy efficiency and capacity for CO2 dissociation. Several CO2 conversion ideas will be introduced, describing the advantages and disadvantages of each conversion techniques.

The plasma reactor has been known as one of the most promising candidate for CO2 dissociation. However, the problems on how to achieve high efficiency, stable discharge at atmospheric pressure, and reliability at high power density have been remained to be solved. An high power ICP(Inductively coupled plasma) source will be introduced along with other sources such as microwave, DBD( Dielectric barrier discharge), and DC for the efficient CO2 dissociation.

In this presentation, the large scale fine dust removal experiment also will be discussed.
