Hydrogen Energy and Hydrogen Safety

Dear Colleagues,

Hydrogen energy stands at the forefront of the transition to sustainable energy solutions and is poised to play a pivotal role in shaping a carbon-neutral future. As nations worldwide intensify their pursuit of decarbonization and strive to enhance energy resilience, the hydrogen economy is experiencing robust growth. This versatile energy carrier is increasingly integrated across diverse sectors such as transportation, manufacturing, and even residential settings. Beyond its role in powering vehicles, hydrogen serves as a critical component in a range of applications, from industrial processes to heating in homes and businesses. Moreover, hydrogen is instrumental in harnessing the potential of fluctuating renewable resources, such as solar and wind energies, to ensure a steady and reliable energy supply. While actively using hydrogen as an energy carrier, hydrogen safety concerns must be carefully managed due to its highly flammable nature. Ensuring robust safety protocols and technologies are in place is crucial to preventing potential leaks and explosions, fostering a safe environment for its storage, transportation, and use across various applications.

This Special Issue aims to report and disseminate the latest advances related to hydrogen energy and hydrogen safety. We invite contributions from researchers and industry experts who are pioneering new technologies, methodologies, and safety measures in the hydrogen sector. The goal is to highlight innovative approaches that enhance the efficiency, usability, and safety of hydrogen as an energy carrier, thereby facilitating its integration into the global energy mix. Contributions that address the technical challenges, regulatory issues, and economic aspects of hydrogen energy are particularly welcome.

Topics of interest include, but are not limited to, the following:

• Hydrogen strategies, policies, and roadmaps;
• Hydrogen production, storage, and transportation;
• Hydrogen infrastructure;
• Hydrogen fuel cells and HFCVs;
• Innovative hydrogen energy processes and technologies;
• Hydrogen safety and codes and standards;
• Behaviors of gaseous and liquid hydrogen;
• Physics effects of hydrogen flames and explosions;
• Hydrogen effects on materials and components;
• Risk assessment and safety management.
