Economic Assessment of Bidirectional Low-Temperature District Energy Systems with Seasonal Energy Storage and Photovoltaic Thermal Hybrid Solar System
Fifth Generation District Heating and Cooling (5GDHC) networks, also called bidirectional low-temperature district energy systems, is a promising strategy that is more efficient for districts with simultaneous cooling and heating demands. This study presents an economic life cycle assessment of bidirectional low-temperature district systems with varying shares of different energy sources. Solar thermal energy and waste heat from the cooling demand in summer can be transferred to the geothermal energy storage to be reused by heat pumps during winter. The capital investment of the heat pumps, geothermal boreholes and photovoltaic/thermal (PVT) systems can be paid back at the end of the lifetime of the project. Additionally, geothermal systems can increase the recovery of the waste heat and solar energy.
