Hydrogen has the potential to be combined with IC engines like CI and SI, which is discussed. Also, hydrogen can supply the whole energy of the vehicle by using a fuel cell, which is a zero emission and sustainable approach. Among the various types of fuel cell vehicles, PEMFC is the most suitable for automotive applications.
Hydrogen storage and batteries should not be viewed as competitors for providing flexibility to the power system; instead, they complement each other in important ways. The ideal mix may be using batteries to provide short-term flexibility (minutes or hours), while reserving hydrogen for long-term flexibility over weeks or months.
