Abstract:The existing district heating system (DHS) in Camminghaburen (Leeuwarden) is dominated by 3rd generation district heating (3GDH) system. This DHS rely on centralized heat producer (Combined Heat and Power plant (CHP)) which consumes natural gas for heat generation. The heat with quite high temperature (75-85 degC) is then distributed by heat networks (water pipes) for customers (heat is used for space heating and domestic hot water (DHW) heating inside buildings). In order to improve the reliability of existing DHS, the DHS needs to be upgraded to accommodate wider scale of heat producers. These heat producers use more sustainable heat sources (geothermal heat, residual heat and biogas) for heat generation. The utilization of these heat sources can reduce natural gas consumption thus help the energy transition process towards low carbon energy supply. In order to discover the improvements needed for upgrade of existing DHS to 4GDH system, the concept of 4GDH system, the characteristics of existing 4GDH system in Netherlands (Mijnwater 2.0 in Heerlen) and existing DHS in Camminghaburen (Leeuwarden) are analysed. Based on this analysis, the differences between existing DHS and 4GDH system are highlighted. After that, the necessary changes on the existing DHS in Camminghaburen are proposed. Some prominent risks that can occur during upgrades of existing DHS to 4GDH system are identified. Difficulty to form good collaborations between multiple heat producers & DHS company (due to issue with contract of heat supply), lack of collaboration between DHS company & housing corporations to coordinate on buildings refurbishment (that can support utilization of low temperature heat supply) and concern of data privacy to be exposed (due to presence of remote heat measurement) are some risks that can be faced during transition from 3GDH to 4GDH system. In order to mitigate these risks, some potential solutions are recommended which is mostly related to changes in local energy policy along with more leadership from municipality to drive the development of 4GDH system.
