Integration kombinierter, erneuerbarer Energiesysteme in die Industrie
Renewable and secure energy supply is of high importance for the industry and, not least due to the international climate targets, can only be achieved through the optimal use of all available resources.
Even in Austria, which has a high share of hydropower, only a part of the electrical energy demand is currently provided by renewable energy sources and it is not conceivable in the near future to cover the heating sector with renewable electricity and thus to electrify it. Therefore, exergetically reasonable alternatives should be used to cover the industrial process heat demand in the low and medium temperature range (<400 °C): Waste heat recovery, solar process heat and heat pumps, each combined with storage, as well as photovoltaic and PVT collectors.
To date, the advantages of a combined integration of different renewable technologies are only realized in the building sector. In industry, although there is a technical and economic potential to cover the industrial process heat demand with renewable energies, the following problems still need to be addressed:
- Criteria and methods for the identification and evaluation of the technically and economically most reasonable selection or combination of possible technologies,
- Design, operation and control strategies for the optimized integration of renewable technology combinations and
- System simulations for the illustration or processing of the above mentioned questions.
The results of the CORES project should be comprehensible global system indicators (key performance indicators), an optimization algorithm for the required system simulations and the control strategies derived from them for an optimized operation of the technology combinations. Furthermore, three concrete implementations are to be initiated by means of real industrial studies.
The CORES project is carried out together with a consortium from Germany and Switzerland. The focus of the Austrian research work is on the in-house optimized integration of the renewable technology combinations. The German consortium focuses on the integration in industrial parks or grid-connected energy supply, the Swiss research group deals with economic evaluation criteria and financing models.
