Energy Systems Analysis and Energy Efficiency

The research field of Energy System Analysis and Energy Efficiency (ESAFE) primarily focuses on the cost-efficient design of sustainable energy systems. The aim is to develop strategic decision-making options for the transformation of municipalities, industrial companies, and households. To this end, we evaluate cross-sectoral systems—such as electricity, heating, gas, hydrogen, and mobility—as well as innovative business models (e.g., neighborhood storage, district heating, tenant electricity models, electrification) from the perspectives of various stakeholders, including households, energy suppliers and companies. Within the framework of applied research, ESAFE endeavors to develop practice-oriented solutions together with our cooperation partners.

In view of the increasing complexity caused by the interactions between energy system components and actors, ESAFE develops quantitative methods for model-based analysis. Our analyses are based on techno-economic simulation and optimization models, which enable a detailed understanding of system dynamics, interactions, and transformation pathways. In addition, we apply statistical models to investigate how user behavior and acceptance influence the cost-optimal design of energy systems.

Research focus

System efficiency and energy storage 
We analyse systems, processes, and technologies regarding their significance for the integrability and increased efficiency in industry, commerce, and households. The aim is to develop strategies to reduce energy consumption and to promote the integration of renewable and volatile energy sources into household, municipal and industrial energy infrastructures. A key aspect of this is the economic evaluation of energy storage solutions (e.g. battery, hydrogen, and heat storage) and the flexibilization of demand (e.g. demand response).

Sector coupling and heat transformation 
Our research focuses on analysing the interactions between different energy consumption sectors, including electricity, heat, natural gas, hydrogen, and mobility, with the aim of exploiting existing synergies. To this end, we develop models to optimize cross-sector energy flows. Among other things, the aim is to develop strategies for the optimal integration of renewable energy sources into the supply of households, neighborhoods, or industrial parks.

User acceptance and transformation management 
Technological issues are only one aspect of the energy transition. We also deal with user acceptance and the behavior of stakeholders (such as end consumers and energy suppliers) in relation to the introduction of new energy technologies. The aim is to develop strategies that help to ensure that society also supports the transformation towards a sustainable energy system. To this end, we are developing regulations and measures to accompany the transformation and promote user acceptance through nudging, for example. This also includes evaluating transformation paths in terms of cost distribution among the stakeholders from a social perspective.
