*'''Scope:''' Use of hydrogen as an energy carrier for transport applications is mostly associated with fuel cells. However, an internal combustion engine converted to or designed for hydrogen, can attain high power output, high efficiency and ultra low emissions, at a cost currently far below that of fuel cells. More importantly, because of the possibility of bi-fuel operation, the hydrogen engine can act as an accelerator for building up a hydrogen infrastructure. This article presents the current state and future prospects for hydrogen engines.
