Research and Development Projects
TLK regularly participates in collaborative research and development projects aimed at developing new methods, models, and software solutions for a variety of application areas. Together with academic and industrial partners, we work to advance innovative technologies and develop practical tools. Below is a selection of our current projects.
TREWAS
Design software for efficient, safe and durable transient cryogenic hydrogen storage systems in aviation
Objective: To develop innovative design software for transient cryogenic H₂ storage systems, with a focus on efficiency, safety, and durability.
TLK Focus: Development of the design software and a service portfolio based on it. The planned software is initially geared toward the needs of the aviation industry but is also intended for use in other sectors in the future, e.g., for the design of cryogenic H₂ storage systems in commercial vehicles or for hydrogen transport.
Partner: TU Braunschweig – Research on innovative operating and control strategies, as well as measurements for model validation.

Objective: To increase the resilience and applicability of new and existing VRFB systems, including through the development of an operational and maintenance guide.
TLK Focus: TLK is developing a new Modelica-based VRFB model as well as a software tool for simulating operational strategies and system designs. This includes modeling efficiency and service life, validation using field data, and the integration of the battery model into a building model provided by our partners. The completed VRFB model will be incorporated into our Modelica libraries, and the software tool will be released as a practical design tool.
Partner: ZAE Bayern, J. Schmalz GmbH, Steinbeis Innovationszentrum energieplus and VANEVO GmbH

Objective: To provide a model-based framework for the dynamic, stable, and real-time analysis, control, and monitoring of industrial high-temperature heat pumps—as part of an overall cyber-physical system.
TLK Focus: Our TIL Suite is already being used extensively for the development of large-scale heat pumps. The libraries are characterized by high accuracy and computational performance. To ensure this remains the case even as complexity increases—particularly when using natural refrigerant mixtures—further developments are necessary. A central focus is on improving the real-time capability of particularly complex simulation models to make them usable for hardware-in-the-loop (HiL) testing, model-based control, and online fault monitoring in digital twins.

Objective: To develop an efficient and lightweight LT-PEM fuel cell system for a short-haul aircraft with a capacity of 100 passengers.
TLK Focus: Further development of our models for robust simulation of mission profiles at the fuel cell system level, including start-up and shutdown scenarios. Analysis of the impact of uneven distribution in multi-stack systems at the stack-to-stack level. Implementation, analysis, and evaluation of phase-separated modeling in the fuel cell system model. Investigation of selected balance-of-plant components using CFD methods and transfer of the results to 0D/1D system simulation.
