This study provides an overview of the existing power scenario in India, power shortages that the country faces, the energy mix that exists in the country, aspects of coal usage, the future plans for expansion of capacity, and GHG emissions. It spells out in detail the spectrum of governmental initiatives to combat climate change and what the thermal power sector has already achieved by way of developing and introducing technologies to increase the efficiencies of a new generation of coal-fired plants. The report also presents the wide array of clean coal technologies worldwide with a particular emphasis on carbon capture and storage, the accompanying storage risks, and the potential for CO2 storage in India. Finally, the study outlines the various research and development initiatives underway in India and also other technology options for India for reducing CO2 emissions through energy efficiency, bio-fuel utilisation, hydel and wind power.

This study report examines the various mercury emission sources, particularly the thermal power sector. It lists a growing number of modern industrial products that use mercury in its various forms: notebook computers, modern telephones, new lighting technologies and anti-lock brakes in cars. It goes on to outline how mercury emissions, once transported through the air, contaminates land and water and can enter the food chain. The study examines the impact of mercury on the health of humans and what is being done worldwide to tackle this very important issue

This study provides a comprehensive overview of the main developments of this technology. Chemical looping is an innovative strategy of excluding gases like nitrogen found in air and delivering only oxygen to the coal combustion process. This enables an almost pure CO2 gas to be produced, which can then be relatively easily stored without any further major processing. This technology is increasingly being viewed as a competitive technology in carbon capture and storage, with the successful completion of pilot plant trials in the EU and US. The study examines the potential of chemical looping combustion and the possibility of its integration into power plants, especially for countries like India which have large coal reserves. The report goes on to point out that an important positive aspect of this technology is that it can be retrofitted into existing power plants.
