Item type:Article, Access status: Open Access , Technological and safety aspects of CNG home fast refueling units(2016) Kuczyński, Szymon; Liszka, Krystian; Łaciak, Mariusz; Olìjnik, Andrìj; Strods, Robert; Szurlej, AdamDespite all global economic shifts and the fact that natural gas is recognized worldwide as the main and the leading alternative to oil products in transportation sector, there is a huge barrier to switch passenger vehicle segment to natural gas – the lack of refueling infrastructure for natural gas vehicles. The key to solving that problem and providing barrier breaking refueling infrastructure solution for natural gas vehicles (NGV) is home fast refueling units. It operates using natural gas (methane), which is being provided through gas pipelines at client’s home, and electricity connection point. It enables an environmentally friendly NGV’s home refueling just in minutes. The underlying technology is one stage hydraulic compressor (instead of multistage mechanical compressor technology) which provides the possibility to compress low pressure gas from residential gas grid to 200 bar for its further usage as a fuel for NGVs. More than efficiency and convenience, the direct hydraulic compressor technology provides compelling cost and lifetime advantages as well as superior convenience over other solutions. Aims of this article is to compare technical, technological and safety aspects of home refueling units and estimate a perspectives of natural gas vehicles as an alternative for regular vehicles.Item type:Article, Access status: Open Access , Analysis of the participation of various components in natural gas transport(Wydawnictwa AGH, 2017) Apostol, Rostislav; Kowalski, Rafał; Liszka, Krystian; Łaciak, Mariusz; Olìjnik, Andrìj; Szurlej, AdamNatural gas is a mixture of hydrocarbons with combustible methane as the main component, the content of which usually exceeds 90%. Among the remaining components of natural gas are ethane, propane, butane, nitrogen, carbon dioxide and sulfur compounds. Helium can be also found in some natural gas fields. The composition of natural gas depends on, e.g. the field from which the gas comes, and also way in which it is transported, i.e. pipelines, LNG technology. The quality of natural gas is regulated by respective standards. Gas transmission pipelines are the most popular and dominant method of gas transport on the international gas market, though LNG technology has recently started to play an increasingly prominent role. The intensive development of renewable energy sources is accompanied by the development of the Power to gas technology - the electric energy excess is used for the hydrogen production, which can be directed to the existing natural gas network and such a mixture of natural gas and nitrogen is transmitted. At present, transmission pipelines for nitride natural gas Ls and Lw exist in Poland. The aim of this paper is to analyze the influence of natural gas admixtures on the operational parameters of transmission pipelines.Item type:Doctoral Dissertation, Access status: Open Access , Rola gazu ziemnego w bilansie paliwowo-energetycznym kraju ze szczególnym uwzględnieniem energetyki w aspekcie wymogów ochrony środowiska(2004-06-24) (Data obrony: 2007) Szurlej, Adam
Wydział Paliw i EnergiiThe main aim of the research was to present the importance and the role of natural gas for the power industry. The aim was achieved on the basis of the economic and ecological analysis. The paper presents multi-dimensional issues concerning the generation of electricity. The discussion covers: the presentation of natural gas as an energy source, the role of natural gas in the national structure of the primary energy resources, the influence of the electricity and thermal generation on the natural environment, the various methods of evaluation of the costs related to the generation of electricity from hard coal, brown coal and natural gas, the optimization of energy resources for the generation of electricity, the analysis of the level of possibility that the energy industry based on natural gas will develop successfully in the future. The study focuses also on the external costs of the electricity generation and their influence on total costs of electricity generation. The analysis of the costs of the electricity generation from natural high- methane gas and nitrogen-rich gas was delved for gas engines, gas turbines and gas-steam blocks.Item type:Article, Access status: Open Access , Role of underground gas storage in the EU natural gas market(2014) Janusz, Piotr; Kaliski, Maciej; Szurlej, AdamOne of the main intentions of the European Union is to create common and liberalizated market of natural gas in Europe. Actions has been taken in this area for a few years, however achived effects do not reach the aims that were assumed at the beginning. The quantity of natural gas consumption in the European Union during last years is characterized by a declining tendency (decreasing usage of natural gas in power sector, higher temperature during autumn and winter season also infulences on limiting of natural gas demand), in 2012 the consumption was forming on the level of 444 billion m$^{3}$, and for example in 2008 it amounted to 497 billion m$^{3}$. The regulations concerning the natural gas market embrace all of the elements which have an impact on building consolidated and liberalizated market, it means: transfer, distribution and LNG, storage. The authors of this article wants to draw one's attention to the particular role of underground gas storages and depict change of the tasks, which they have to fulfill on the liberalizating market of natural gas in Europe (ie. Price arbitration). The purpose of this article is to present the current situation on the market of storage services, which means available storage capacities, the level of their usage and plans regarding extension and constructing of new capacities.Item type:Article, Access status: Open Access , Analysis of the methods for gas demand forecasting(2017) Apostol, Rostislav; Łaciak, Mariusz; Olìjnik, Andrìj; Szurlej, AdamNatural gas is a very important and strategic resource. In the structure of the world’s primary energy, its share is currently approx. 25 % and according to the forecasts it will continue to grow. In addition, the transition the large cities to gas as the main energy resource is an effective solution for reducing harmful emissions and improving air quality. The trend of increasing consumption of natural gas causes the complex technical issues, especially the need of accurate forecasting the gas demand, design the new distribution networks and modernization of the existing systems of gas supply. This article presents a review of existing methods for gas demand forecasting based on the gas engineering literature analysis and the approach for the forecasting of gas consumption based on the analysis of the gas consumption diagrams of gas station.Item type:Article, Access status: Open Access , The effect of hydrogen transported through a gas pipeline on the functioning of gas compression station work(Wydawnictwa AGH, 2017) Zabrzeski, Łukasz; Janusz, Piotr; Liszka, Krystian; Łaciak, Mariusz; Szurlej, AdamThe production of hydrogen based on excess electricity and transporting it by pipeline as a mixture with natural gas may be an excellent completion of an energy system. When dealing with gas transmission over long distances, gas compression stations become an integral part of the natural gas grid, providing desired pressure of this source of power in pipes. In this paper the effect that hydrogen admixture has on the main parameters of the operation of gas compression stations was described.
