Student visit to Chemnitz University of Technology: Exchange about hydrogen technologies and renewable energies in the student laboratory.
Students discover future technologies: hydrogen and renewable energy!
On May 23, 2025, students from New Delhi and Marienberg visited the Technical University (TU) Chemnitz. This exchange took place as part of a student exchange program between the Marienberg High School and the Bal Bharati Public School in New Delhi. The students had the opportunity to learn about alternative forms of energy, including the production, availability and storage of various energy sources.
Dr. Martina Wanke, head of the “Wunderland Physics” school laboratory, introduced the group to how fuel cells work. In the Faculty of Mechanical Engineering, the topic of green mobility was discussed, with the focus being on the use of hydrogen in vehicles. Dr. As part of his presentation, André Bergmann introduced the hydrogen cycle and explained its importance for the future of energy supply. In addition, Dr. Manfred Karras conducted an experiment on biodiesel in the chemistry laboratory.
Practical experiments and insights into research
In the school laboratory, the young people were able to carry out physical experimental studies on wind power and build an organic solar cell. Chemnitz University of Technology attached great importance to providing students with practical experience. After the lunch break, the students visited the high-voltage laboratory of the Faculty of Electrical Engineering and Information Technology, where they discussed current topics in energy transmission and power electronics.
The visit to Chemnitz University of Technology was not only educational, but also closely linked to the research priorities in hydrogen technology. Hydrogen has established itself as a key technology for achieving climate goals. There are different types of hydrogen, such as gray, blue and green hydrogen. The latter is generated from renewable energy sources and plays a crucial role in the decarbonization of industry and transport.
The role of hydrogen in the energy future
According to current reports, hydrogen is predominantly produced from fossil raw materials such as natural gas and coal, with gray hydrogen causing significant CO2 emissions. Green hydrogen, on the other hand, could help reduce dependence on fossil imports and increase security of supply. Austria has set itself the goal of becoming climate neutral by 2040 and is therefore conducting intensive research into hydrogen technologies in order to emerge as an innovation leader, especially in mobility.
The use of hydrogen as a chemical storage in renewable energy systems is also being researched. Surpluses from wind and solar power can be converted into hydrogen, which can then be stored in the natural gas network. These technologies enable the coupling of the electricity, heat and mobility sectors and make an important contribution to the stability of the electricity grid.
Additionally, there are advances in fuel cell technology, which converts chemical energy into electrical energy and heat very efficiently. In Austria, research is supported not only by national strategies, but also by international collaborations, such as participation in the IEA hydrogen technology program. These initiatives aim to overcome technological barriers to hydrogen production and improve the infrastructure for hydrogen applications.
The discussions about MINT courses at Chemnitz University of Technology underline the growing interest in research in the areas of hydrogen and renewable energies. The students and researchers work together to develop solutions that could revolutionize both industry and mobility. This makes it clear that future energy supply will be significantly shaped by innovative approaches in the area of hydrogen technologies. In this context, further training and raising awareness among young people about these forward-looking topics is of utmost importance.
TU Chemnitz reports that the students received intensive insights into innovative energy technologies. Loud Energy Innovation Austria Green hydrogen is essential for future energy supplies. The Fraunhofer IKTS provides valuable insights into the application and storage of hydrogen in various sectors and highlights the need to develop sustainable and economical solutions.
