With an ultimate goal of stabilization of greenhouse gases in the atmosphere, new scientific approaches are being researched worldwide leading to a shift in the policies from low carbon and no carbon energy sources to fossil fuel sources with capture of carbon and its storage or permanent fixation. The carbon capture and storage is no doubt a progressive approach to limit CO2 concentration in the atmosphere. In India, CO2 fixation research has been initiated on novel amine based, multiphased absorbents and innovative adsorptive materials in different R&D laboratories. New possibilities exist in biofixation of CO2 from the flue gases through microbial and microalgal processes. There is need to intensify R&D efforts further for development of cost-effective regenerative adsorbents and processes. It is also important that advanced coal combustion technologies are investigated keeping in view the properties of coal and the concept of zero emission plants. Emerging trends in advanced coal combustion processes and challenges in R&D towards zero emission coal based power generation are enumerated.
