Researchers at TU Darmstadt are at the forefront of investigating the utilization of green hydrogen in future energy systems, particularly focusing on its combustion in gas turbines and aircraft engines. The team, led by Dr.-Ing. Hendrik Nicolai and Professor Christian Hasse, has gained access to the JUPITER supercomputer as part of the GCS Exascale Pioneer Call. Their project 'HyCoMES' aims to model hydrogen combustion using exascale simulations, a critical aspect of the energy transition towards sustainable practices. By leveraging the powerful computing capabilities of JUPITER, the researchers can conduct detailed simulations that capture the intricate dynamics of turbulent hydrogen flames under realistic gas turbine conditions. Prof. Dr.-Ing. Christian Hasse expresses pride in the selection of their project as a lighthouse application on the first European exascale computer, highlighting the potential for fundamental scientific inquiries to align with practical challenges. The collaboration with international partners and the focus on AI methods demonstrate a holistic approach to integrating research with industry needs, potentially driving advancements in hydrogen technologies. The project not only enhances understanding of hydrogen combustion but also inspires students to engage with cutting-edge research shaping the future of energy systems. The involvement of TU Darmstadt in NHR4CES, a collaboration with RWTH Aachen University, further emphasizes the commitment to advancing computational engineering and high-performance computing. By expanding the hardware and software capabilities through experiences gained from JUPITER, the university aims to support users in various research endeavors. This initiative signifies a significant step towards innovative hydrogen gas turbine development and the broader implementation of green hydrogen in the energy sector.
