Comparison of the cumulative energy demand of BEV’s and FCEV’s in their long-term operation

Sitnik Lech J.

Combustion Engines

2024

R. 63, nr 1

24--29

The paper presents a method of using the theory of cumulative energy demand to assess this demand in long-term operation of vehicles with a mileage forecast of up to 350,000 km. Based on the results of operational "consumption" of energy and taking into account the energy "costs" of obtaining it, a comparison of the currently popular BEV’s (Battery Electric Vehicles) and FCEV’s (Fuel Cell Electric Vehicles) was presented. The question arises how much energy must be used to propel vehicles in their natural operation. After calculating using available data, the answer is - by operating FCEV’s on average, two times more electricity is needed than by operating BEV’s.

Purpose: The aim of this paper is to present the possibilities of using hydrogen buses in urban transport taking into account technological, economic and environmental conditions. Design/methodology/approach: Analysis of international literature, Polish literature and reports related to the development of alternative energy sources in vehicles and urban transport development. Findings: The Polish government to achieve the environmental requirements of the European Union obliges local government units to ensure the share of zero-emission buses in the fleet of vehicles in use. On the basis of the conducted analysis we can say that a significant advantage of hydrogen vehicles is the total lack of emissions, a long range of up to 350-400 km and short charging times. However, a significant problem is insufficient infrastructure - not enough hydrogen stations. Despite this difficulty, more and more manufacturers are interested in producing hydrogen vehicles, and investors are seriously considering the costs and benefits of zero-emission buses. Unfortunately, none of the economic analyses that have been commissioned by Polish companies providing transport services have shown the viability of using hydrogen buses. Originality/value: The paper shows the global trends in the development of city buses with particular attention to hydrogen buses.
