CSIR- CECRIKaraikudi, has ventured in search of a viable solution to capture the polluting Carbon-di-oxide (CO2) from thermal power plant flue gas and has emerged successfully with an innovative technology that matches with the Department of Energy (DoE), USA targets as well. The novelty of CSIR-CECRI’s invention lies in the synthesis process to produce an adsorbent capable of adsorbing more than 3 millimoles per gram of CO2 at flue gas conditions.
The process know-how has been transferred to M/s Summits Hygronics Private Limited based at Coimbatore (a leading manufacturer of air drying units, and medical oxygen generators for industrial and medical applications). This technology could be used in multiple areas like thermal power plants, submarines, biogas enrichment, automotive sector and direct air capturing in highly polluted cities thereby minimising CO2 concentration leading to reduction in global warming. The so captured CO2 could also be converted into value-added industrially important chemicals like methanol, formic acid, adipic acid, etc. enabling a circular economy.
As this technology is in alignment with one of the United Nation’s “Sustainable Development Goals on Climate Action” (SDG 13) and the Government of India’s mission on “Carbon Capture, Utilisation and Storage (CCUS)”, it paves way for joint efforts of a research institute with a renowned industry to address a major global mandate towards fulfilling India’s commitment in realising “net-zero” emission by 2070.
