| Abstract | Most ofthe primary energy consumption in the world, about 86%, is still based on fossil fuels. Coal is the most abundant fossil fuel resource worldwide with reserve-to-production ratio of 112 years. It supplies 30.3% of primary energy demand of the world and contributes42% to the world's electricity generation. Carbon Capture & Storage(CCS) is considered to be a cost-competitive technology as compared to other mitigation technologies. There are some uncertainties and risks associated with deploying CCS at large scale in the world.The major drawback is the additional capital expenditure and extra energy requirements on CO2 capture process. Pakistan has vast coal reserves of 185 billion tonnes, though its current share in the overall electricity generation mix is only is only 0.1%. Coal fired power generation is considered to be the largest point source of emissions. The government has planned to generate20,000 MW from coal power plants by 2030.The estimated CO2emissions from 7 future coal powerplants are 28.5 MtCO2. The energy sector emissions will continue to grow at compound rate of 11% annually to level of 2730 million tonnes by 2050, if business as usual scenario is considered. The government hopes this increased use of coal to be equipped with clean coal technologies and deployment of Carbon Capture and Storage.The results of applying CCS technology on one of Pakistan’s future coal power plants shows that there is increase of 61.9% and 90.6% in overall cost of the project and cost of electricity respectively. The efficiency is reduced by 30% and electrical output decreased by 14.5%.The CO2and SO2emissions reduced by 90% and 99.6% respectively. It is important to consider all the aspects of CCS effects on a power plant before its large scale implementation on coal power plants.The technology is new and requires heavy investment costin which major contribution as to come from the government.The government has to plan considering all the supporting factors also like high technological capability, skilled manpower, vast research and development, physical infrastructure for transport and storage of CO2, awareness among the public, complete technology knowledge from design to operation and maintenance, stringent environmental standards and monitoring and control systems in place for appropriate storage sites. At present there are no policies or plans in place to implement this technology. So, to start up with implementation, Pakistan should focus on research and study this technology indetail before implementation. |
