- Investments in the hydrogen industry have been recently intensified as this fuel is considered to be a relevant part of the green energy transition. Since the transportation sector is one of the main targets to reduce fossil fuel utilization, it is crucial to investigate the use of hydrogen fuel for automotive applications. Therefore, in this paper, the powertrain of a battery electric vehicle versus a hydrogen fuel cell was compared considering for both scenarios hydrogen as the fuel. Accordingly, in the first scenario, hydrogen is used as the source of electricity to power the battery electric vehicle while in the second scenario, it is used as the fuel for the propulsion of a fuel cell vehicle. For the boundary and criteria utilized here, the hydrogen fuel cell vehicle consumed 13% less hydrogen per km compared to the battery electric vehicle. Thus, the results show that in the case that hydrogen is available as fuel, a hydrogen fuel cell vehicle would be more energy efficient, in terms of driving range.

- The high energy consumption by the residential sector makes it a relevant sector to address efficient and clean electricity use, and thus, a potential application for hydrogen fuel cells. Therefore, in this work, proton-exchange membrane (PEM) fuel cell systems of different sizes are simulated as combined heat and power technologies for a house in Sweden. Two cases are investigated: with no energy storage besides the hydrogen storage and, with a lithium-ion battery as energy storage. For all the cases, we have shown that fuel cells are promising devices to be applied as combined heat and power technologies. Using the battery as the energy storage, the house energy systems could reach efficiencies of 84-88%. The results obtained indicate a promising path for hydrogen application and thus, for a cleaner energy transition.
