Hydrogen is becoming an important energy carrier of the future. It can be produced from renewable electricity, can be stored and transported in gaseous or liquid state as well as using hydrogen derivatives. Hydrogen will contribute to well-to-wheel and life cycle CO2 neutral solutions for future mobility. Important automotive markets like China, United States, EU, Korea and Japan have already started and will accelerate the build-up of a hydrogen refueling infrastructure.
Following a technology open approach, and complementary to fuel cells, hydrogen engine powertrains are considered as attractive option. Potential starting points could be commercial vehicle applications, where high load operation, long driving distances as well as short refueling times are important. Next up could be light commercial vehicles, especially for fleet applications where a fully developed hydrogen refueling infrastructure is not required. With further development of the refueling station network, hydrogen engine powertrains can be attractive also for passenger car applications.
This presentation focuses on hydrogen engine applications, powertrain topologies and operating strategies. Subsystems and components like fuel injection and exhaust gas treatment are considered. The results demonstrate feasibility and attractive characteristics of hydrogen engine powertrains for future mobility
