Over the next three years, the UK Government Department for Business, Energy and Industrial Strategy (BEIS) are investing £320m of capital funding into heat networks via the Heat Networks Investment Project (HNIP). Heat networks have the potential to substantially contribute to the UK’s ambition to decarbonise heat, however only if the source of heat for the network is low carbon.
 
One of the most effective ways of decarbonising a heat network is to use solar heat and we invited to the UK two National Experts from the IEA SHC Task 55 (Towards the Integration of Large SHC Systems into District Heating and Cooling (DHC) Networks) to speak on Solar Heat Networks. They were Jan Erik Nielsen from the renewable energy planning specialist PlanEnergi (Denmark) and Christian Holter from the solar engineering company SOLID (Austria). We also invited three UK experts to speak: Grant Feasey from the solar collector manufacturing company AES Solar; Renaldi Renaldi from Newcastle University; and Edmund Papworth from the small-scale heat network company, Minus 7. 
 
The details of the Solar Academy event were as follows: 
• Title: Solar Heat Networks: Policy, Planning, Design and Performance 
• Time: Friday 8th March 2019 09:30–17:00 
• Location: Department for Business, Energy and Industrial Strategy (BEIS) Conference Centre, London 
 
A copy of the agenda can be found on page 3. The following topics were discussed: 
• Introduction to Solar Heat Networks 
• Integration of Solar into Heat Networks 
• Integration of Seasonal Heat Storage into Heat Networks 
• ESCO Models and System Performance

The programs of Solar Heating and cooling (SHC) as well as District Heating and Cooling (DHC) belong to the 5 main technology collaboration programmes (TCP) of the IEA (International Energy Agency). SHC was among the first programmes of the IEA established in 1977. Its goal is to promote the use of all aspects of solar thermal energy.

Solar District Heating: Inspiration and Experiences from Denmark
Solar District Heating: Inspiration and Experiences from Denmark
August 2017 - PDF 1.82MB - Posted: 2017-11-30
By: Danish District Heating Association / PlanEnergi
Publisher: IEA SHC TASK 55
This document brings together some of the most important experiences from the inspiring development of solar district heating systems that have been seen in Denmark in the past years. The document is an adapted translations of “Solvarme – Inspirationskatalog” from February 2017, elaborated by PlanEnergi for the Danish District Heating Association. Some of the conditions and regulations described might be specific Danish. The main objective of this document is to inspire and qualify the district heating companies (board members as well as operating personnel) as well as representatives from municipalities with respect to the specific processes in the project development phases. This is not a proper guidance in the establishment of solar installations. More specific guidance can be found in IEA SHC Task 45 and Task 55 guidelines and fact sheets and in the Europeran SDH projects – see last section in the document. This document thus complements these guidelines with specific Danish experience. After summing up to the various protagonists follow descriptions of six specific Danish solar district heating plants – and some experiences gained here.

Subtask C: Design of the Solar Thermal System and of Hybrid Components

Large collector fields are increasingly being integrated into district heating systems. Due to the operation mode of these networks, the solar system must provide the desired supply temperature. Therefore, knowledge of thermal-hydraulic behavior and energy efficiency are very important for planning, operation and control. The study presents the investigation of two large-scale solar collector fields in Chemnitz (Germany). For the detailed study of heat transfer and hydraulic behavior of the field, mobile monitoring has been installed on selected rows in addition to the conventional monitoring system. The measurement results show that large collector fields with differently sized rows, consisting of a large number of collectors with a dividing manifold (below) and a combining manifold (above) connected to a large row, can be operated with a variable flow rate (matched flow). With the provided measured values, comparison of the desired/actual values and the calculation of absolute and relative parameters are performed. The Brühl solar district heating system has been in operation since summer 2016 and meets the expectations of thermal performance and efficiencies.

Industry and researchers are collaborating to assess how best to integrate large scale solar thermal installations in combination with hybrid technologies into district heating and cooling networks. Besides the international scope of this work, what also makes it unique is that the IEA SHC Programme has teamed up with the IEA District Heating and Cooling Programme to ensure that the right stakeholders are involved.

In recent years, megawatt-scale solar thermal district heating (SDH) systems have gained increasing attention globally. Several ambitious projects were successfully implemented in countries such as Austria, Germany, Italy, France, Spain, and Norway. Large-scale SDH systems and their large-sized seasonal storages have become attractive options for cost effective and low carbon heat supply. In the next step, large systems will become even bigger and likely grow from MEGA to almost GIGA-sized installations. These systems will be able to meet the increasing energy demand of city districts and of whole cities. Compared to conventional heat generation systems, the effective operation of a SDH network and its seasonal storage can guarantee a primary energy consumption reduction of >70% in thermal needs. However, the actual integration of large solar thermal systems into existing and new networks faces several challenges. Expertise on the integration of large solar thermal systems into district networks is limited. Therefore, SHC Task 55 collects and disseminates technical and economic solutions to leverage large-scale solar thermal district heating and cooling systems worldwide.

SHC Task 55 aims to provide a platform for practitioners and scientists to elaborate on the benefits and challenges of SDH and SDC systems. It elaborates on options and measures to realize sophisticated SDH and SDC systems by focusing on characteristics of solar thermal systems, technical and economic specifications of district heating networks that are relevant for the integration of solar thermal systems and hybrid technologies, analyses of system components and their integration, modular designs of large SDH/SDC systems, and economic requirements of large SDH/SDC systems in different market regions. Finally, SHC Task 55 is a collaborative project with the IEA Technology Collaboration Programme on District Heating and Cooling including Combined Heat and Power (IEA DHC).
