Setting the scene: Security of energy supply World R/P ratio – recent trends, local variations (2001-2006) Per definition “reserves” are sources that are know and deemed economically exploitable. China: 48 years India: 207 years EU-27: 63 years USA: 234 years Australia: 210 years Former Soviet Union: 464 years  EC/EEA, 2004: India is supposed to double its CO 2 emission from year 2000 by 2012 Mitigating climate change: cannot ignore fossil fuels

  • 16. Concluding remarks <ul><li>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. </li></ul><ul><li>Whereas the relative importance of greenhouse gas emissions is rather high in Europe, India is evenly concerned because of severe impacts of global warming. </li></ul><ul><li>In addition India is (probably) more concerned about cost and the continued use of domestic coal reserves . </li></ul><ul><li>As the isolation of CO 2 constitutes an inherent feature in polygeneration , capture is a logical step to pursue. </li></ul><ul><li>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 . </li></ul>
