Opis:
In the time, when the whole world is increasingly engaged in environmental protection, it is necessary to come up with a fuel alternative for transportation, which means generally abandon the use of non-renewable resources (petrol, oil and fossil fuel in general), as they are one of the many factors influencing the emergence of greenhouse gases and the associated global warming. In today's Europe, the pressure is put mainly on automotive companies, to search for sources other than conventional fuels. At present, there is a big boom in the area of electric cars powered from the power network – the vast majority of electric energy, however, is produced in fossil fuel power plants. The second option of possible development in this area is the use of hydrogen as an alternative fuel. This technology, whether it be direct combustion as in diesel or eventually in petrol engines, or energy production in a hydrogen fuel cell, is certainly the way suitable for further development. With hydrogen as a fuel, it is possible to reduce pollutants almost to zero. The article presents a comparison of electricity generated using renewable and non-renewable sources and focuses on a closer understanding of the myth of the dangers connected with using hydrogen as fuel. Furthermore, compares conventional fuels to re-newable hydrogen technologies and focuses on the hydrogen combustion engines together with hydrogen storage and application in transportation.

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.
