The goal of the project is to bring experience, knowledge and solutions for the 4 th Generation District Heating systems to a level where they are ready to be implemented widely.

• Phase I: document experiences in mature DH countries with very low temperature systems serving highly energy-efficient new-build developments

• Phase II: analyze and extend the scope of lessons arising from early examples of low-temperature systems, in order to improve the cost-effectiveness and environmental benefits, effectively formulating a blueprint for a new generation of district heating.

High Grade Resources

• Have reliably high temperatures that always exceed the DES supply temperature, and can be used directly whenever it is available.

Low Grade Resources

• Have lower temperatures that are sometimes or always insufficient relative to the DES supply temperature but always sufficient relative to the DES return temperature.

• If the temperature of the source falls below the DES supply temperature, the temperature must be polished with other energy sources.

Below Grade Resources

• Always have temperatures lower than the return temperature in the DES, and must be upgraded with a heat pump.

Renewable Energy & Waste Heat (REWH)

• At what temperature is the Renewable Energy or Waste Heat (REWH) available, and how does it compare with the supply and return temperatures of the DES?

• Representative resource temperatures (at left), with heat pump increase shown in grey.

• Tools for obtaining actual technical status of pre-insulated bonded pipes in operation

• A model for decision making regarding actions to be taken based on

– Technical status– Forecasted operational parameters– Requirements on robustness & redundancy– Costs for energy loss, maintenance &

reconstruction• Predicted degradation & remaining technical life based

on– Accelerated aged pipes– Pipes from field operation– Synthesis of available studies

• The accelerated ageing of pipes with both a standard and a thinner casing is continuing.

• The pipes are exposed to an ambient temperature of 70°C. The service pipes are kept at four levels: 70°C, 130°C, 140°C and 150°C

• Hence, accelerated ageing cause both deterioration of PUR at service pipe and deterioration of polyethylene casing.
