Technical and economic potential of highly efficient boiler technologies in the Korean industrial sector

다국어 초록 (Multilingual Abstract)

<P><B>Abstract</B></P> <P>Energy saving potential and carbon dioxide (CO<SUB>2</SUB>) reduction potential of boiler technologies in the Korean industrial sector up to 2035 were analyzed using The Integrated MARKAL-EFOM System (TIMES) model based on bottom-up optimization. Final energy consumption by industrial indirect heating boilers in 2013 accounts for 7% of Korea's industrial energy consumption and 8% of the manufacturing sector's consumption. Energy consumption of industrial indirect heating boilers is expected to increase about 25% in the baseline scenario between 2013 and 2035. Technical potential against the baseline scenario by deploying only the most efficient technologies in new installation demand is 7.9% for energy saving and 20.7% for CO<SUB>2</SUB> reduction by 2035. The most efficient technologies by boiler technology types were gas-fired super boilers. Economic potential against the baseline scenario through market competition between existing and high efficient technologies is 5.6% for energy saving and 6.1% for CO<SUB>2</SUB> reduction by 2035. CO<SUB>2</SUB> reduction potential is higher than energy-saving potential because fuel substitution toward gas was added to the energy-saving effect due to efficiency improvement. Research and development, information disclosure, regulation, and incentives for high-efficiency boiler technologies are necessary to realize technical potential as well as economic potential in industrial indirect heating.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We analyze technical and economic potential of highly efficient boilers in Korea. </LI> <LI> Energy saving potential is 7.9% technically and 5.6% economically by 2035. </LI> <LI> CO<SUB>2</SUB> reduction potential is 20.7% technically and 6.1% economically by 2035. </LI> <LI> Gas-fired super boiler will be the dominant technology in the mid- to long-term. </LI> </UL> </P>
