For passenger cars, various powertrains compete in terms of reducing environmentally-harmful emissions, smooth integration into future energy systems and economic performance. Developing a sound long-term projection of the total cost of ownership (TCO), however, remains challenging. Highlights of our present assessment, include a detailed, component-based manufacturing and operating cost analysis, as well as simulation-based component scaling and fuel consumption analysis. We apply this methodology to eight passenger car concepts based on batteries, fuel cells and combustion engines , spanning four passenger car segments and five different market development scenarios through 2050. With respect to the TCO, our analysis reveals that fully-electric powertrains utilizing batteries (BEVs) and fuel cells (FCEVs) offer the lowest-cost solutions. FCEVs exhibit small but robust benefits compared to BEVs. BEVs will undergo the earliest break-even point with internal combustion engine vehicles (ICEVs), already before 2030. Different market development scenarios would not significantly affect the long-term results. |
