29. Conclusions • Fossil fuels will continue to have major share in primary energy fuels globally • Coal is dominant fuel meeting 69% of nation’s current commercial energy demand • Emerging CCS options would make coal based thermal power generation environmentally friendly • High cost of carbon capture and carbon storage and fall in efficiency of a power plant remain main barriers • Pre-combustion CO2 sequestration requires more technology development efforts but may provide cost-effective solutions in the long run and can be used in conjunction with renewables

30. Future Prospects • Our energy capacity has to grow to meet basic needs of People and coal use need to be sustained • Carbon capture technologies are not fully developed and the cost is prohibitively high. • There is a need for Generation of Industry Support and Partnerships • The cost of CO2 sequestration is also the main barrier in acceleration of research efforts. Other means of covering the cost through income from energy fuel recovery or carbon credits not adequate. • Require more attention to Infrastructure Development as the CO2 Storage Projects are Large Scale projects
