Pan European Networks: Government
Reliability and quality
The main aim of the InSun project is to demonstrate the reliability
and quality of large scale solar thermal systems for different types
of industrial process heat applications on medium and higher
temperature levels. Supply level, as well as process level
integration, are addressed and combined with a detailed process
analysis to identify potentials for energy efficiency measures.
Missing standards especially for concentrating collectors and the
large uncertainty of system integration costs are the main
bottlenecks for a fast system deployment in the industrial sector.
Therefore, the project also aims to give a significant input to the
standardisation process in terms of construction, integration and
dimensioning of this young and innovative technology.
Research tasks focus on the analysis and optimisation of the
integration process of the solar systems into the industrial
processes and on the combined performance of the solar
systems together with the industrial processes involved. Detailed
monitoring data of the three systems will be used to analyse and
improve the combined system control and to demonstrate the
performance of the three different collector types and their
specific application at different seasonal conditions.
To increase the reliability of large scale solar thermal systems
covering a high fraction of the process heat (>20%), a permanent
and automated monitoring system is needed. Therefore, internet-
based monitoring and analysis tools will be developed. These
prototypes will be implemented in the demonstration systems
and combined with innovative simulation based fault detection
and predictive control tools.
Based on the technical outcomes within the InSun project, current
market deployment strategies are upgraded and shared among
the actors involved in the solar thermal market for large
installations. The overall objective of this task is to support the
marketing plan of the technology providers by focusing on
selected elements such as price reduction potentials, funding
schemes and ESCo models.
Current status of InSun
The first two solar systems of InSun started operation in
spring/early summer 2013. The thermal oil driven part of the
Fresnel collector field (1,056m
) with indirect steam generation at
the brick fabrication of Laterizi Gambettola SRL in Italy was
completely installed in March 2013 and the improved flat plate
collector field (1,140m
) at the meat producer Berger in Austria in
June 2013. The remaining part of the Fresnel collector field in Italy
and the solar system installation with parabolic trough collectors in
Spain are planned to be installed and completed in autumn 2013.
The research project InSun presented here has received
funding from the European Union’s Seventh Framework
Programme FP7/2007-2013 under grant agreement no
RHC-ETP, ‘Common vision for the Renewable Heating and Cooling Sector in
Europe’, public report, 2011.
