This paper uses a bottom-up, techno-economic model to analyze India's energy security and greenhouse gas emissions, focusing on the potential of advanced coal technologies and CCS options to reduce CO2 emissions.
Rapid shift from traditional energy intensive pathways is required to pace-up economic growth before exhausting remaining carbon budget under 2 degrees C global stabilization target. Within this larger context, in this paper we have used AIM/End-use, a bottom-up, techno-economic model to analyze India's energy security and greenhouse gas (GHG) emissions from the year 2000 to 2050 with a focus on possibilities of coal continuance in India. Our analysis shows that by adopting advanced coal technologies and carbon dioxide capture and sequestration (CCS) options, up to 45% CO2 emission reduction can be achieved over business-as-usual scenario (BAU) by 2050. This is possible even when coal use would increase to nearly 2200 Mt in 2050 as against 870 Mt in 2017-18. Without CCS, coal use could peak at 1200 Mt with 22% CO2 reduction over BAU in 2050 but in that case nuclear and renewable energy would become pivotal in meeting energy demand. The paper concludes that a win-win inte-gration of energy security and deep GHG emission mitigation is possible through a large-scale integration of advanced coal technologies and CCS in Indian energy systems. We have also provided a brief PESTLE analysis for finding the enabling environment necessary for achieving the results discussed in various scenarios.
