Opis:
In recent years, regarding the influence of the production processes and vehicles on the environment, new technical solutions for reducing air pollutions have been studied and developed. One of the new constructions is fuel cell electric vehicle (FCEV). The production and running conditions of the vehicles are specific in different countries. Hence, a study of these conditions and fuel production process is needed. In this paper, a study of the FCEV efficiency, at different producing technologies of hydrogen (H2), is carried out. Life cycle assessment (LCA) method is used. A comparison, concerning fuel consumption and emissions as CO2 equivalent for the whole life cycle, is done for FCEV and conventional gasoline vehicle (GV). The influence of the energy mix and technology of production of hydrogen on spent energy and air pollution is analyzed. As the results show, in countries with CO2 emissions over 447 g per 1 kWh electricity, the technology of hydrogen production from natural gas is most effective. Now and in the near future, the ecological and financial advantages, connected to renovation of existing vehicle fleet with FCEV, are not absolutely verified.

Opis:
The publication analyses the possibility of separating hydrogen from coke oven gas for further use in the transport sector in the FCEV segment (fuel cell electric vehicles). The construction of the separation installation using the PSA (pressure swing adsorption) method guaranteeing high purity of hydrogen was assumed, according to the requirements of ISO 14678-2:2012 and SAE J-2719 standards. The PSA technology is widely used in industrial gas separation processes, however, due to the composition of coal gas, which apart from hydrogen and methane consists of impurities in the form of hydrocarbons, sulphur compounds, chlorine, etc., it needs to be adapted to the needs of separation of hydrogen from coke oven gas. The study shows the total possible hydrogen production potential and then, in agreement with the JSW Group’s Coking Plants, limits were set for hydrogen production in PSA technology at Przyjaźń, Jadwiga and Radlin Coking Plants, without the negative impact of the separation installation on technological processes associated with coke oven battery firing, operation of existing power units, gas compression systems and taking into account securing the needs of external customers for coke oven gas. Additionally, in order to determine the Polish market demand for high-purity hydrogen, an analysis was carried out which indicates that in 2030 the share of FCEVs will be 2%, so the demand for hydrogen in this segment would be negligible compared to the supply of hydrogen produced in a large-scale installation. Due to the need to build such a market and adapt the parameters of the installation to the variable parameters of coke oven gas, the pilot scale of the installation and the target location of the installation at the Przyjaźń Coking Plant were indicated as the most optimal.

Opis:
This study analysed the greenhouse gas (GHG) emissions of hydrogen fuel cell vehicles’(FCEVs’) life cycles. These included models running on hydrogen derived from coke oven gas (COG), which is a by-product of the coking process of coal and includes hydrogen, methane, and other gases. FCEVs and hydrogen have the potential to drive future mobility. Hydrogen can be separated from the COG in the process of pressure swing adsorption to obtain a purity of hydrogen that meets the requirements of a hydrogen FCEV. An environmental life cycle assessment (LCA) of FCEV powered by hydrogen produced from Polish COG was conducted. The direction of hydrogen production strategies in Poland was also presented. The analyses included the entire life cycle of FCEVs with the production of hydrogen from COG in a Polish coke plant. A comparative analysis of FCEVs and other alternative fuels was conducted, and the main determinants of GHG emissions of FCEV were given. Importantly, this is the first attempt at an environmental assessment of FCEVs in Poland.
