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.

The way of directive of the European Parliament and the Council in 2014/94 on October 22nd 2014 in the case of infrastructure development of alternative fuels which was specifically concerned with calls to reduce oil dependence on transport in European countries was imposed due to the necessity to formulate specific provisions in individual nations in the Union. In correlation to this, on the day of 11th January 2018 the act on electromobility and alternative fuels was passed, which came to be on the day of 1st September 2018 with changes implemented later on. The regulations mentioned above oblige public transport to partially replace their diesel engine-based rolling stock and introducing changes to alternative fuels (compressed hydrogen in gaseous form belongs to such fuels). Support systems in Poland are an important element in the implementation of modern and ecological technologies. Very often those solutions are much more expensive compared to the ones used so far. The financing provided by them enables the realization of such projects in our environment. In this work, the idea of emission-free public transport operating on the basis of electric vehicles (Battery Electric Vehicles) as well as hydrogen (Fuel Cell Vehicles) will be presented. Both of these variants will be compared and their working principle are going to be shown. The analysis of support systems for the development of emission-free public transport on a European, national and regional level will also be presented. All collected information will form a compendium of information essential to implementing the public transport project in Polish conditions.

Hydrogen can have great importance in seven areas of necessary changes in the transformation of the power system, including transport (especially motor transport), industrial processes, thermal and energy production in the construction industry and production processes. Hydrogen fuel cell electric vehicles (FCEVs) do not cause local air pollution because they have zero “tailpipe” emissions. Essential are ecological and functional aspects of operating vehicles equipped with fuel cells. However, noteworthy is also the development of the refilling infrastructure. The functionality of FCEVs to a considerable degree depends on the functionality of fuel cells.

Wodór może mieć ogromne znaczenie w siedmiu obszarach niezbędnych zmian transformacji systemu elektroenergetycznego, w tym w transporcie (zwłaszcza w transporcie samochodowym), procesach przemysłowych, produkcji ciepła i energii w budownictwie oraz procesach produkcyjnych. Elektryczne pojazdy wodorowe z ogniwami paliwowymi (FCEV) nie powodują lokalnie zanieczyszczenia powietrza, ponieważ mają zerową emisję z „wydechu”. Istotnymi są ekologiczne i funkcjonalne aspekty eksploatacji pojazdów wyposażonych w ogniwa paliwowe. Jednak istotnym jest także rozwój infrastruktury ich tankowania. Funkcjonalność pojazdów (FCEV) w istotnym stopniu zależy od funkcjonalności ogniw paliwowych.
