This document summarizes statistics comparing energy usage in the European Union and India and discusses options for co-producing electricity and synthetic fuels from coal in India using carbon capture and storage (CCS) technologies. It notes India's growing energy demand and limited supply as well as environmental issues from coal use. It then outlines CCS technology options like coal gasification and pre-combustion carbon capture that could allow continued coal use while reducing emissions. The document concludes that CCS could help justify harnessing India's domestic coal reserves in a sustainable way while extending the use of fossil fuels.

- 16. Concluding remarks The energy situation in India is a matter of growing concern especially in terms of security of energy supply , which may bring India into advanced coal-gasification technology to co-produce electricity and synthetic fuels polygeneration. Whereas the relative importance of greenhouse gas emissions is rather high in Europe, India is evenly concerned because of severe impacts of global warming. In addition India is (probably) more concerned about cost and the continued use of domestic coal reserves . As the isolation of CO 2 constitutes an inherent feature in polygeneration , capture is a logical step to pursue. CCS offers the option of extending the fossil era , and to justify the harnessing of carbonaceous fuels and indigenous coal as a compatible option within a sustainable framework .
