Speech: Navigating Challenges and Opportunities for Hydrogen as Sustainable Energy Future
The escalating hydrogen demand, expected to surge eightfold by 2050 compared to 2020, poses multifaceted challenges for its energy sector deployment. Hydrogen's exceptional calorific value, ranking second at 120-142 MJ/kg, positions it as the prime energy-to-weight ratio among conventional fuels. Green hydrogen production, with readiness levels around 7-8 and commercial readiness indices of about 4-5, commands a significant 30% market share with 55-80% efficiency and production costs of $4-7/kg H2. While costs are projected to reach $1-2/kg H2 in the future, integrating various production processes is crucial, transcending mass-scale production. Metal hydride emerges as an economical hydrogen storage solution at $125/m3, while ammonia leads with a low specific energy cost of $13/GJ. Streamlined infrastructure development is imperative for efficient storage, transportation, and delivery. This exhaustive review encompasses hydrogen production, storage, costs, and applications, offering insightful analysis and guidance on hydrogen's energy carrier challenges. Achieving sustainable development goals by 2050 necessitates integrated planning, infrastructure, cost reduction, net-zero emissions, and innovative storage. Policymakers, researchers, and scientists can utilize this review as a blueprint to shape hydrogen's future role in energy.

Speech: Some recent development of compressed air energy storage technologies
This presentation discusses the current development and advances of compressed air energy storage technology. The general concept of compressed air energy storage technology will be first introduced. Then a new concept of combined pump hydro and compressed air energy storage systems was proposed and the performance of the combined system was evaluated under different working conditions. The effect of the key parameters such as storage pressure, initial pressure, and compression process on the system performance was further studied and reported. Furthermore, the heat and mass transfer in the compression air storage vessel was analysed, and its impact on the compression process and system performance was investigated. Finally, the latest research on wave-driven compressed air energy storage was briefly presented. This lecture highlights the potential and design consideration of the compressed air energy storage system in real applications.

Speech: High Performance Textile Aerodynamics in Elite Sports
The application of science and technology can improve sports performance. Particularly in high-speed sports like ski jumping, cycling, skiing, bobsledding, sprinting, speed skating, and swimming, aerodynamics is seen as a decisive element in winning margins and elite sporting competitions. Wearing sports apparel has advantages over traditional clothing for athletes. As a result, aerodynamic performance in sportswear is increasingly being considered while designing sportswear. Evaluating the aerodynamic performance of sports textiles is essential to producing aerodynamically successful sports gear for faster-paced activities. The main goal of this article is to highlight some aero/hydrodynamic research done at RMIT University on high-performance textiles used in speed sports and the ramifications of the research findings for competitive sports and other domains.
