Projects

Decarbonisation of traffic - feedbacks with the energy system - global to regional (DeVKopSys2) 01/2022 - 10/2024 Prof. Dr. rer. nat. Hoffmann, Clemens Nacken, Lukas; Dr. Krebs, Friedrich	The project objectives include analysis of impacts of decarbonisation in the traffic sector and analysis of the global potential to supply P2X fuels under consideration of national transformation pathways.
Heat Transition of the Urban Building Stock by Interactive Decision Space Analysis 08/2022 - 07/2025 Prof. Dr. rer. nat. Hoffmann, Clemens Dr. Krebs, Friedrich; Dr. Holzhauer, Sascha; Digel, Ivan; Kaiser, Alwina	The project WAERMER shall apply a methodical integration of energy system optimisation on an urban level and agent-based modelling of individual investment behaviour including preferences and scope of action. It shall help identify the requirements for a successful transition of heat provision in the urban building stock towards CO2-neutrality. Building owners are surveyed about relevant factors of their investment decision making. In an iterative process, measures to incentivise individual investments can be developed and simulated as well as required adaptations to the technical energy system identified. The agent-based modelling explicitly considers the influence of energy consultants and craftspeople concerning their changing knowledge and recommendations.
Development of a Lidar- and AI-supported method for large-scale measurement of the wind field inside and outside offshore wind farms (WINDOW) 06/2021 - 05/2024 Prof. Dr. rer. nat. Hoffmann, Clemens Dr. Callies, Doron; Dr. rer. nat. Basse, Alexander; Dr. Wiemer, Martin; Hildebrand, Tabea	Subproject: Development and test of methods for the generation of a lidar- and AI-supported wind field on the basis of measured data
