Smart Low-Carbon District Heating and Cooling for Seoul
Seoul, a 10 million population city, is implementing various policies to reduce greenhouse gas emissions and improve energy efficiency. Seoul has a high population density and limited available land; it is a disadvantage for large scale development of solar PV and wind power. However, there are well-equipped district heating and cool infrastructures, and environmental facilities. Also, Solar PV, solar thermal, heat pump, and waste-to-energy are mature technologies. To minimize greenhouse gas emissions, and improve air quality, a system is needed that optimizes these technologies. A smart district energy system can meet the heat and electricity demand by using co-generation, and multiple regional energy resources with less emission and energy consumption. This presentation discussed cases of temperature difference energy utilization in district heating, highlighted the potential benefits of smart low carbon district energy system, and emphasized what policies are needed to realize the potential benefits.
