Ongoing projects


This project aims to take a first step towards the conversion from natural gas to hydrogen in the field of open-die forging.


Innovative Projekte

Based on a newly built office building in Karlsruhe, the aim of this project is to make the energy supply more flexible in an energy-efficient and system-friendly manner for modern commercial buildings, as well as, to decarbonize them to a large extent.


Decarbonisation of the energy supply of the building stock

The aim of the project is to decarbonise the heat supply of existing buildings and thus eliminate the use of fossil natural gas. For this purpose, cold local heating networks are designed bidirectionally and solar heat from the summer is stored seasonally in the ground and used in winter.

Completed projects


In the WIN4Climate NKI-project, procedures and solutions for a system-serving heat transition in a real corporate environment were developed between 2019 and 2022 together with IREES GmbH. Together with stakeholders from the energy industry, the energy supply of ten industrial complexes was systematically investigated, partly using simulation, optimisation and analysis tools developed in-house.


Guide to decarbonisation in the industry




The energy transition leads to an increased share of renewable energies and decentralised generation capacities. Here, sector-coupled prosumer systems can contribute to a secure and cheap energy supply and the storage of energy, as well as support grid stability. Within the ACA-MODES project, the energy laboratories of the project partners developed and tested cross-system, grid-serving control algorithms and operation management strategies for sector-coupled, hybrid energy systems.

Optimisation-based control methods offer great optimisation potential both for the operation of air conditioning systems and for the operation of systems for regenerative energy generation. The solar air-conditioning system of the Faculty of Management Science and Engineering, which went into operation in October 2016, allows these methods to be investigated in a combined application from both fields. The OPT-NES project developed methods and software for this purpose.



In the Interflex4Climate NKI-project, economic and ecological potentials of inter-company energy interconnection and load flexibilisation in industrial areas were identified and optimised based on mathematical optimisation between 2016 and 2019 together with IREES GmbH. More than 40 companies in eleven industrial areas were investigated.
