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.

Nearly every other year the transistors that power silicon computer chip shrink in size by half and double in performance, enabling our devices to become more mobile and accessible. But what happens when these components can't get any smaller? George Tulevski researches the unseen and untapped world of nanomaterials. His current work: developing chemical processes to compel billions of carbon nanotubes to assemble themselves into the patterns needed to build circuits, much the same way natural organisms build intricate, diverse and elegant structures. Could they hold the secret to the next generation of computing?
