Hydrogen-based automotive applications: a promising future

Transportation is one of the main sectors responsible for greenhouse emissions worldwide. Its transformation will be crucial for facing problems related to climate change. The massive use of hydrogen as the main energy vector in transportation may represent a great opportunity to transform the mobility industry, especially if this fuel is produced through renewable resources. However, the use of hydrogen as an energy vector presents an important challenge for efficiency and transportation. This chapter presents an updated description of advances in automotive applications based on hydrogen fuel. It also identifies main applications in public transport based on hydrogen, and their limitations and benefits. Advances in multienergy service stations, which include hydrogen refueling and energy management, and possible limitations, are studied. Finally, a brief description is provided of the future of hydrogen technology in automotive and public transport applications as well as refueling.
