Research focus EST
Sustainable energy systems of the future will be characterized by renewable energies, sector coupling, system-supporting data exchange, as well as intelligent control and regulation within decentralized subsystems. A fundamental reorientation of the entire energy system is essential for this transformation.
The field of Energy Systems Engineering is dedicated to researching and developing these future energy systems. This includes the holistic, systemic analysis and quantification of the interactions between efficiency measures, the integration and direct marketing of renewable energies, sector coupling concepts, as well as traditional energy storage within a regional, renewable energy system from an energetic, economic, and ecological perspective. Transformation possibilities are examined based on energy demands within a specific area. Key considerations in weighing different options include questions of energy transport, site selection, and operation.
The research activities can be divided into the following overlapping areas:
1. Modeling of Energy Systems
A central part of our work involves the development and application of methods for modeling complex, integrated energy systems. On the one hand, questions concerning the planning and operation of energy systems under technical, economic, and social uncertainties are investigated and translated into methods. On the other hand, approaches for better consideration of spatial, temporal, and sectoral dimensions are further developed. The latter includes, among other things, the energetic coupling of the regional, decentralized energy system with other decentralized systems or an overarching central system, to address questions like "How much decentralization is necessary or possible?"
2. Energy Transition in Industry
The aim of this research area is to explore approaches and solutions for achieving climate-neutral and sustainable production. Since the majority of greenhouse gas emissions are associated with the material and energy use of fossil fuels, the development of technical concepts always starts from the energy needs of the processes. The focus is on aspects of resource and energy efficiency, energy carrier switching, as well as circularity and the role of industrial plants in future energy systems.
3. Space Heating Transition
In addition to process heat, the energy demands for space heating are of high interest for a successful energy transition. Besides decentralized solutions for individual buildings, pipeline-bound heating supply concepts (district and local heating) with central heat generation from renewable energies or waste heat from industry and commerce are also viable options in densely populated areas. In all cases, future concepts have significant impacts on existing and future energy networks. Our research includes both the development and evaluation of individual options and the analysis of scenarios for municipalities and regions in the context of the global energy transition.
