The future choice of technologies and co-benefits of CO2 emission reduction in Bangladesh power sector

This paper examines the impacts of CO2 emission reduction on future technology selection and energy use in Bangladesh power sector up to 2035 considering the base year 2005. It also examines the implications of CO2 emission reduction targets on energy security of the country. The analysis is based on a long-term energy system model of Bangladesh using the MARKAL framework. The results show that the introduction of the CO2 emission reduction targets directly affect the shift of technologies from high carbon content fossil-based to low carbon content fossil-based as well as clean, renewable energy-based technologies compared to the base scenario. With the CO2 emission reduction target of 10-30%, the cumulative net energy imports during 2005-2035 would be reduced in the range of over 1400 PJ to 4898 PJ compared to the base scenario emission level. The total primary energy requirement would be reduced in the range of 5.5-15.2% in the CO2 emission reduction targets and the primary energy supply system would be diversified compared to the base scenario.
