Energy concept post 2030

The “Energy Concept post 2030” resulting from the EnEff:Stadt Campus Lichtwiese project forms the basis for the future energy supply structure of the Lichtwiese campus, after the current energy contracting contract ends in 2030. Based on the results of the other sub-projects, specific recommendations for action for an overall concept will be developed. The key objective is to achieve the reduction targets set by the university with regard to energy requirements and CO2 emissions.

Currently, the energy supply of the TU Darmstadt is mainly based on natural gas-powered generation plants. The operation of these plants can be made successively more efficient through a multi-modal approach and by investigating the variability/flexibility of demand. However, this alone will not be sufficient to achieve the targeted reduction of CO2 emissions by 80 % compared to 1990 by 2050. In this subproject, the remaining reduction gap will therefore be quantified. In order to close this gap, different scenarios will be developed on how this gap can be closed as cost-effectively as possible. The focus is on renewable heat sources such as geothermal or solar thermal energy and heat pumps using the highly volatile renewable electricity generation.

The “Energy Concept post 2030” is intended to support the university management in the tendering process for a new contracting period for the Lichtwiese campus in the form of scientific and technical recommendations for action. The concept paper to be prepared should include a long-term investment plan, which shows the optimal dimensioning of the generation or storage technologies used for the various scenarios in order to minimize overall costs while at the same time achieving the reduction targets.
