  • Sustainable heat supply
  • Model-based energy system analysis
  • Sector coupling
  • Studies, consulting and concepts for thermal energy systems
  • Large heat storage systems and large heat pumps
  • Climate neutrality in industry

Dr Tobias Zimmermann’s consulting focus at Hamburg Institut is on the development of strategies for sustainable heat supply and the analysis of coupled energy systems. Among other things, he is deputy project manager of the research project “Optimised Integration of Thermal Aquifer Storage in District Heating Systems”(OptInAquiFer), which is funded by the Federal Ministry of Education and Research (BMBF). As part of this project, a consortium has been researching the contribution of aquifer storage for large district heating networks in the course of the upcoming decarbonisation and transformation since 2022.

Professional experience & qualification

After studying energy and environmental technology at the Technical University of Hamburg (TUHH), he worked as a research assistant at the Institute of Energy Technology at TUHH. There he researched the integration of renewable energies into the energy system with a focus on the topic of sector coupling. In his doctoral project on the role of the heating sector in the energy transition, Tobias Zimmermann developed complex simulation models for energy system analysis.

His expertise and market knowledge, including on the subject of large heat storage systems, are also appreciated at overarching levels. Dr Tobias Zimmermann is a member of the long-term heat storage working group organised by Solites and the AGFW. This group aims to exchange information and discuss construction methods and system integration of large heat storage systems. He is also a member of the international technology collaboration programme “Energy Storage – Task 45”, which deals with accelerating the use of large thermal energy storage systems as part of a multi-year collaboration.

Dr Tobias Zimmermann is an approved assessor according to FW609 and FW611 at the AGFW
