Solar energy for Networks and the Industry , presentation given by Florian Ruesch (OST)
Thermal grids are essential for replacing the fossil dominated heat production in densely populated areas. Therefore, the major Swiss cities will invest several billions of CHF in the expansion of their district heating systems.
The integration of solar heat and thermal energy storages in thermal grids allows saving valuable renewable fuels such as biomass and provides a possibility to replace fossil fuels for peak and summer loads. Large solar thermal installations for grids experience an international boom. The pioneer country Denmark has realized large solar thermal installations with an overall surface of more than a million of square meters reaching heat production costs of less than 40 EUR/MWh.
Large heat consumers with similar scaling effects can be found in industry, where process heat is responsible for about 10 % of the national energy consumption.
In the last years, some pilot projects have been built and analysed in Switzerland. Despite of promising potential evaluations in research projects, the international progress did not (yet) lead to a similar boom in Switzerland.
This talk will:
- give an overview on international developments and the situation in Switzerland,
- discuss the potential and challenges for large solar thermal installations in Switzerland,
- show some results of related research projects at SPF-OST
- suggest future requirements and next steps.
