Real-time in situ studies are essential to understand the dynamic behavior of catalysts under operational conditions. X-ray absorption spectroscopy (XAS) offers a unique, element-specific probe of electronic and structural changes at the active sites of electrocatalysts during electrochemical reactions. At BAM, collaborative research efforts leverage the advanced capabilities of the BAMline at the Berlin Synchrotron BESSY-II to study electrocatalytic materials under realistic working conditions. As a dedicated materials research beamline, the BAMline enables in situ and operando XAS across different time and length scales, making it ideally suited for monitoring catalytic transformations in real time. This presentation highlights the analytical strengths and sample environments developed for electrochemical cells at BAM, showcasing their application to electrocatalysis for energy conversion (e.g., water splitting, CO₂ reduction). Emphasis will be placed on how these insights contribute to the rational design and real-time optimization of functional materials for a sustainable energy future.

This transformation faces numerous challenges in the areas of safety and security including natural hazards. A safe, reliable, decarbonized energy supply requires diversification and a combination of different climate-friendly energy carriers and storage systems that are tailored to the specific requirements of industry, households and transportation. However, each energy carrier must be specifically assessed in terms of safety regarding its production, storage, transport and use. Relevant safety aspects arise from the scale at which energy carriers such as hydrogen and ammonia, but also electrical energy storage systems, must be handled. Suitable transport and storage infrastructure must be established for each energy carrier and storage facility, leading to extreme safety, technological and regulatory challenges. Central energy supplies are categorized as critical infrastructure. In the context of geopolitical conflicts, they are increasingly becoming the focus of digital or analog attacks by third parties, particularly with the aim of unsettling the respective population. The digitalization and automation of energy systems increases their vulnerability to such attacks. Geopolitical conflicts also lead to problems with the availability of raw materials and energy carriers. Also in this context, greater focus must be placed on diversification and resilience concepts. For the energy transition to succeed, traditional safety and security concepts must be interdisciplinary integrated with new aspects of resilience and crisis prevention. These concepts must be continuously developed to avoid outdated and expensive solutions. At the same time, it is reasonable to assume that the nature of threats will change more rapidly than in the past. The presentation will highlight key challenges associated with the widespread introduction of various energy carriers and storage technologies. It covers a wide range of topics, from safety-related and material-related issues to infrastructural and digital requirements as well as to aspects of security.

The binding goal of the EU and Germany to reduce net zero carbon emissions by 2045 will substantially increase the demand for green hydrogen as an important carbon-free substitute for fossil fuels. The World Energy Council expects an annual demand of 60 million tons (equivalent 2.000 TWh) hydrogen and its derivatives (especially ammonia and methanol) in the EU until 2050. lt is estimated that the EU can produce less than half of its needed hydrogen by 2050, and will need to import the rest. African coastal countries therefore have the opportunity to become net exporters of their carbon-free regenerative energy in the form of hydrogen and its derivatives and to enable better economic growth and generate wealth on the African continent. The large-scale production, transport and storage of green hydrogen will require large investments in the development of knowledge and training, logistics and capital goods - for both the EU and African countries. BAM is already facing the lack of skilled workers and hydrogen experts. By bundling its expertise in the field of hydrogen technologies into a competence center H2Safety@BAM to create confidence in the technology The topic of hydrogen has been current at BAM for more than one hundred years and is also currently the focus of numerous research and cooperation activities. In order to transfer its expertise in this field BAM developed a number of education activities. The centre of all activities is the Graduate School “Trustworthy Hydrogen”, established in 2022 together with the BTU Cottbus. In the presentation all activities and especially those of the graduate school and details of the cooperation with the University of Namibia are shown.

To be able to achieve the targets defined by 2045, the EU and the German government have drafted a framework for action and are making long-term investments in research, development and the rapid implementation of innovative hydrogen technologies. The conditions for a successful energy transition and the economic use of green hydrogen as a clean energy carrier are Hydrogen readiness and a rapid market ramp-up, as well as the establishment of the necessary value chains in the national and European framework. Reliable quality and safety standards are the prerequisite for ensuring safety of supply and environmental compatibility and for creating trust in these technologies. BAM has bundled its expertise in the field of hydrogen technologies into a competence center H2Safety@BAM to create confidence in the technology and to support the hydrogen strategies of the German government and the EU. The topic of hydrogen has been current at BAM for more than one hundred years and is also currently the focus of numerous research and cooperation activities. The competence centre H2Safety@BAM and its vision of “We build trust in hydrogen technologies” will be presented with its many safety-related topics, which can be found throughout the entire hydrogen value chain. Two deep dives will present the results on projects dealing with the design-to-cost issue of classical pressurized gas storage containments and the consequences of the release of liquid hydrogen, which will be roughly compared to the release of ammonia.

Owing to their large internal surface area, these structures can efficiently drive the Faradaic reactions in a RFB. However, the electrochemical characterization of novel CFs, or modified CF-materials is a cumbersome task. This is essentially related to the complex mass-transport phenomena which are convoluted with the electrode kinetics. This talk will focus on ex-situ cyclic voltammetry and operando electrochemical impedance spectroscopy as electroanalytical techniques for porous RFB electrodes. Common pitfalls in the voltammetric analysis of CFs are elucidated and recent strategies for modeling and evaluating CV experiments on porous structures are introduced. Finally, a method based on electrochemical impedance spectroscopy is introduced which allows for an operando fingerprinting of electrochemical reactions in a vanadium-based RFB.
