IEA DHC TS5 - Integration of Renewable Energy Sources into existing District Heating and Cooling Systems (RES DHC)

The expansion of sustainable district heating/cooling is an essential part of the Austrian heat transition. The transformation of these supply systems to fully renewable systems requires the combination of a multitude of aspects. The aim of the project is to compile a data and knowledge base from international projects in this context. Expertise and process know-how for the process of implementing the transformation of district heating and cooling systems will be collected and processed.

Short Description

Introduction

Although there are already successful examples worldwide on the topic of "transformation of FWK systems towards fully renewable systems", an analysis of these examples is still pending. Further development of existing technical concepts for other technical, economic and geographical framework conditions is necessary. An essential innovation content in this project is therefore the compilation and use of a large data and knowledge base from different international projects in this context. Not only expertise in this field, but also process know-how for the implementation process of the transformation will be collected and processed.

Objectives

To gather knowledge of improved solutions for the integration of RES installations into existing FWK systems, and to demonstrate how to deal efficiently with non-technical market barriers and opportunities.
To provide practical know-how on business cases and technical solutions for stakeholders and market actors.
Innovative demo cases should be prepared in cooperation with stakeholders (both for technical and organisational solutions).
Renewable heat sources should be established as environmentally friendly and emission-free heat generation technologies for the FWC sector.

Results

The results of the project will strengthen the technical and thus also the economic competence of Austrian market parties (e.g. energy supply companies, planners, technology providers), as well as provide municipalities and public bodies with new knowledge for the planning of district heating systems and the associated achievement of climate protection goals. The project results will not only refer to Austrian conditions, but will also include international experiences and problems, so that this will open up new markets for planners and technology providers, for example. The project results will provide an easy access to methods and information for the target groups and stakeholders, which are essential for the upcoming implementations of RES in existing FWK grids, as this can and will be an important step for Austria towards achieving the climate targets.

The project will enable the project partners to deepen and broaden their knowledge and experience in the field of RES in FC. This will also result in a knowledge advantage and new research questions that can be addressed in further innovative projects. Furthermore, the project strengthens the national and international position and visibility, which will make the consortium more attractive for customers from industry and energy supply and position it as a partner for future research and development projects.

For the national processing of the results and dissemination, the organisation of a workshop with relevant stakeholders and presentations at national conferences are planned.
