“…Honda states that their 2014 model of 1.6 litre diesel engine weighs 160 kg and can output 88 kW, giving it a power-to-weight ratio of 0.55 kW/kg [43]. The 2005 Mercedes OM642 is stated to weigh 208 kg at a power rating of 173 kW, resulting in a power-to-weight-ratio of 0.83 kW/kg [44]. In 2011, the engine was improved to output 195 kW, but no weight is mentioned [45].…”

Climate change is one of the major problems that people face in this century, with fossil fuel combustion engines being huge contributors. Currently, the battery powered electric vehicle is considered the predecessor, while hydrogen vehicles only have an insignificant market share. To evaluate if this is justified, different hydrogen power train technologies are analyzed and compared to the battery powered electric vehicle. Even though most research focuses on the hydrogen fuel cells, it is shown that, despite the lower efficiency, the often-neglected hydrogen combustion engine could be the right solution for transitioning away from fossil fuels. This is mainly due to the lower costs and possibility of the use of existing manufacturing infrastructure. To achieve a similar level of refueling comfort as with the battery powered electric vehicle, the economic and technological aspects of the local small-scale hydrogen production are being investigated. Due to the low efficiency and high prices for the required components, this domestically produced hydrogen cannot compete with hydrogen produced from fossil fuels on a larger scale.
