Summary
The transition toward sustainable transportation is accelerating globally due to rising energy demand, stringent emission regulations, and the urgent need to mitigate climate change. Electric mobility has emerged as a key solution; however, its widespread adoption depends heavily on advancements in energy storage systems, hydrogen technologies, and fuel cell integration.
Conventional lithium-ion batteries face challenges related to energy density, charging time, lifecycle degradation, and raw material limitations. In this context, next-generation energy storage systems, hydrogen-based energy carriers, and fuel cell technologies offer promising pathways to overcome these barriers and enable long-range, high-efficiency, and low-emission transportation systems.
The aim of this Special Issue is to bring together cutting-edge research contributions addressing innovative materials, system designs, modeling approaches, and hybrid energy systems for electric mobility applications. The scope includes experimental studies, numerical simulations, AI-driven optimization, and techno-economic analyses focused on improving performance, safety, and sustainability of advanced propulsion systems.
Suggested themes include:
· Advanced battery technologies (solid-state, lithium-sulfur)
· Hydrogen production and storage methods
· Proton exchange membrane fuel cells (PEMFC)
· Hybrid battery–fuel cell systems
· Thermal management strategies
· Power electronics integration
· AI/ML-based energy optimization
· Lifecycle assessment
· Infrastructure development for hydrogen
· Electric mobility ecosystems
This Special Issue aims to foster interdisciplinary collaboration to accelerate the commercialization of next-generation clean mobility solutions.
