The German Aerospace Center (DLR) is at the forefront of hydrogen technology research, with a strong focus on developing sustainable solutions for aeronautics, space, energy, and transportation sectors. DLR has been actively involved in all aspects of hydrogen research, including climate-friendly production methods like water electrolysis and biogas reforming, as well as storage, distribution, and utilization technologies. The institute is exploring the use of hydrogen in various applications, from powering trains and vehicles to industrial processes and electricity supply. DLR is also investigating the potential of hydrogen fuel cells for mobile and stationary applications, along with the development of hydrogen-powered gas turbines for industrial and energy sectors. The institute is actively engaged in technology assessments to facilitate the transition from fossil fuel-based systems to hydrogen-based economies, offering a unique blend of laboratory and industrial-scale facilities for developing practical solutions. Experts from DLR's institutes, such as the Institute of Engineering Thermodynamics, are leading the way in hydrogen research, covering a wide range of topics from materials to system-level development. They are involved in projects related to hydrogen electrolysis, storage, fuel cell component development, and system integration for optimizing both stationary and mobile applications. By collaborating with industry partners and participating in events like the H2 Tech Expo, DLR aims to drive innovation and foster the adoption of hydrogen technologies for a sustainable future.
