Solar process heat. Supporting industrial and commercial processes with solar thermal energy.

Artikel

Most users are familiar with solar heating plants above all for space heating or supply of domestic hot water in residential buildings. Rightly so: around 90% of all systems are installed in single- and two-family homes (as of 2015). However, there are other areas in which it can make sense to use solar thermal energy. These include for example the integration of solar thermal energy into local and district heating networks, solar air conditioning and solar process heat for industrial and commercial use. For companies who want to save on energy costs in the long term and improve their own CO2 balance, integrating solar thermal energy into their processes can be an interesting option. The extent to which costs can be saved with a solar heating plant depends on many factors: the scale of the measures, the technology selected and not least the future development of energy prices. One thing is certain, however, and that is that a solar heating plant contributes towards reducing CO2 output. Since heat cannot be transported over long distances at low loss, only those sites are suitable for using solar process heat which offer both favourable irradiation conditions and sufficient space to set up collectors. During periods of low solar irradiation, conventional systems have to cover the full energy requirement. The integration of solar heating plants is an interesting option for companies that operate only during the day and with processes for which a comparatively low temperature is required. Here, the food industry has suitable areas of use, for example. Unlike space heating and domestic hot water, solar process heat is used in operations for the production, further processing or finishing of products, or for the provision of a service that requires process heat. The use of renewable energy sources for the provision of heating and cooling is supported by the market incentive programme for the promotion of renewable energy sources on the heating market (MAP) funded by the German Federal Ministry for Economic Affairs and Energy. Here, there are also funding opportunities for process heat generated in solar heating plants. The system concepts for industry and commerce vary much more widely than domestic applications. Planners must adapt the solar heating plants to the individual requirements of each company. This publication introduces special technical features and typical areas of use, and provides guidelines and funding opportunities for the use of solar process heat.
