IEA SHC Solar Academy: Large Scale SHC Systems Integration into District Heating and Cooling Networks
The International Solar Energy Society is very happy to host the IEA SHC Solar Academy's 2019 series.
This first webinar will share the latest results of IEA SHC Task 55 on Large Scale SHC Systems Integration into District Heating and Cooling Networks.
Solar District Heating (SDH) is in the early market development stage. Large solar thermal plants feeding into district heating networks represent only about 1% of the installed capacity of solar thermal systems, despite the fact that competitive prices lower than 40 €/MWh can be reached. In the long run, solar district heating could represent 4-15% of the total technical potential of solar thermal energy.
The aim of this IEA SHC work is to develop technical and economic requirements for the commercial market introduction of solar district heating and cooling (DHC) for a broad range of countries. The activities aim to improve technological know-how, market know-how and understanding of the boundary conditions as well as to provide expert know-how for project initiation and implementation and for training. A key element will be the direct cooperation of SDH experts with associations and companies in the district heating sector as a means to bridge the gap between these sectors.
The 90-minute webinar will include a 30 minutes Q/A session where attendees can submit their questions to the speakers.
The webinar is organized by the Solar Academy of the IEA SHC Programme and hosted by ISES, the International Solar Energy Society - the webinar presentations as well as the recording will be made available on both the IEA SHC and the ISES website after the webinar.

Speakers
Bärbel Epp (Moderator)
Bärbel Epp is the founder and managing director of the agency Solrico – solar market research & international communication, a network of solar thermal professionals worldwide. She is responsible for the international newsletter on the web portal www.solarthermalworld.org, which has been dedicated exclusively to the solar heating and cooling sector. She graduated in physics and looks back at more than 20 years of journalism in the field of solar thermal energy.
Jan Erik Nielsen
Jan Erik Nielsen is M.Sc. in mechanical engineering and has been active in the field of solar heating for more than 30 years. He has been involved in system design and monitoring of large scale solar heating systems for many years and was operating agent for Task 45 “Large Scale Solar Heating and Cooling Systems” (2011 – 2014) and is now a subtaskleder in Task 55. Jan Erik works with PlanEnergi, a consulting company pioneer in the field of Renewable District Heating in Denmark. Jan Erik Nielsen will present experiences from Danish large scale seasonal storages – including measured performance, showing that it is possible to obtain very low store heat losses.
Presentation Title: Seasonal storage of solar district heating
Sabine Putz
Sabine Putz is head of the Research and Development department and Chief Technology Officer (CTO) and member of the Management Board of SOLID. Here, she is involved in numerous R&D projects on solar thermal heating and cooling at the national, European and international level.
As Operating Agent of Task 55, Sabine will present the Task structure, scope and the main objectives of Task 55.
Presentation Title: IEA SHC TASK 55 - Towards the Integration of Large SHC Systems into DHC Networks
Lucio Mesquita
Lucio Mesquita has over twenty years of experience in the research, design, and testing of solar thermal products and systems for heating and cooling applications in industrial, commercial and residential markets in several countries including Canada, Brazil, China, and the United States. Currently, he is focused on the performance analysis and improvements for the Drake Landing Solar Community and on the cost-reduction and optimization of large-scale renewable energy communities.
This demonstration project, designed to achieve over 90% solar fraction, was commissioned in the summer of 2007 and it is currently in its 12th year of operation. Lucios presentation will describe the system design and its measured performance through out the years.
Presentation Title: Drake Landing, a high solar fraction district heating system
Karin Rühling
Karin Rühling is a Senior Researcher at the Institute of Power Engineering and holds a Professorship of Building Energy Systems and Heat Supply of the Technical University of Dresden.
She will present methods and simulation results concerning the decentralized feed in of solar thermal heat and heat from block heat and power plants into existing district heating systems.
Presentation Title: Decentralized feed-in in existing district heating networks - comparison of the hydraulic effects of solar thermal and CHP
Jianhua Fan
Jianhua Fan works as associate Prof. in the Department of Civil Engineering at the Technical University of Denmark. The focus areas of his research are solar heating systems and energy storages. In his webinar presentation, Jianhua Fan will talk about solar heating plants and system integration of different renewables for example, solar heat, heat pump and biomass etc. and several application examples will be introduced.
Presentation Title: Integration of different renewables in a solar heating plant
IEA SHC Solar Academy
The SHC Solar Academy is the latest effort by the IEA SHC Programme to share it’s work and support R&D and implementation of solar heating and cooling projects worldwide. The academy includes webinars by IEA SHC experts on specific results and tools and hosted by ISES, videos highlighting IEA SHC's work and other relevant issues, national days for the exchange of information between national experts and IEA SHC experts and onsite training by IEA SHC experts is offered by request in IEA SHC member countries.
