Lu began his presentation with a brief outline of the role of functional nanomaterials in addressing global challenges and advancing green hydrogen technologies. He highlighted the critical importance of electrodes, membranes, catalysts and photocatalysts in enhancing the efficiency and scalability of electrolysis and photocatalysis systems, as well as the significance of solid-state storage materials in overcoming challenges related to hydrogen storage and distribution, noting that some low-pressure solutions are already in use.
Still, Prof. Lu emphasised that further technological innovations are needed to reduce costs and enhance performance. He explained that green hydrogen is a valuable energy carrier; it can not only contribute to decarbonisation in the power sector, but also act as zero-emission fuel for sea, land and air freight, which is crucial for the achievement of a net-zero future by 2050. In conclusion, Prof. Lu called on the academic community to accelerate the commercialisation of new materials for the construction of cost-effective hydrogen infrastructure, and urged researchers to bridge the gap between technology R&D and practical applications.

Energy storage will be of major importance when more and more energy is produced using fluctuating renewable sources like wind and solar power. This course concerns two energy storage methods: storage in the form of the artificial fuel hydrogen, and storage in the form of batteries. In the transition to a sustainable-energy future, both hydrogen and batteries will likely play increasingly important roles. Hydrogen has the advantage of effectively limitless scale up potential while batteries have the advantage of high energy efficiency. Methods for sustainable and renewable hydrogen production include solar, wind power, direct photo-electrolysis of water, thermal and nuclear methods as well as biological options. The students will learn about such production methods of hydrogen using renewable energy sources, and separation technologies for clean hydrogen. The application of hydrogen requires cheap, safe, lightweight and easy to handle storage of hydrogen. The course presents current options for storage of hydrogen, including light metal hydrides, large adsorption surface, and nanostructured materials, as well as gaseous and liquid hydrogen storage. It will be explained that the ultimate solution still needs to be found. Students will get an overview of most recent advances and bottlenecks, synthesis and characterization techniques. The electrical energy storage in batteries concerns the principles of (rechargeable) batteries, mainly Li-ion, and the relation of the performance with material properties. The relation between properties at the atomic level with the real life battery performance will be displayed. The principles will be explained in terms of basic electrochemistry and thermodynamics. The course will present recent advantage in the field of Li ion batteries. In addition super-capacitors, allowing fast (dis)charge and based on similar principles, are part of the course.
