Hydrogen, as an energy carrier, is widely regarded as a potential cost-effective, renewable, and clean energy alternative to fossil fuels in order to mitigate the energy shortage and environmental pollution that are currently being faced. The rapid development of advanced materials in hydrogen production, storage, and utilization has opened up a new avenue for the conversion and utilization of hydrogen energy. This book summarizes the current research progress in these areas and is expected to aid in the development and design of advanced materials to improve hydrogen production, storage, and utilization.
