    Opis:
    The Upper Silesian Branch of the Polish Geological Society (PGS) was established in 1962 as one of the first regional branches of the PGS. Due to the specificity of the region, geologists working in Upper Silesia were most often concerned with the exploration and exploitation of hard coal in the USCB, but also undertook research on the geology of the USCB margin, polymetallic deposits, hydrocarbons, hydrogeology, and environmental protection in areas of mining activities. These problems were expressed in the topics of PGS annual meetings, field sessions and seminars. During the 60 years of activity, five PGS meetings were organized, the topics of which concerned the latest achievements in geology in the region. Already in the first years of operation of the Upper Silesian Branch of PGS, it was noticed that a special feature of this branch is the considerable dispersion of geologists working in various cities of the voivodeship. However, despite the difficulties resulting from this fact, the Upper Silesian Branch is active and it has been consolidating the scattered community of geologists in the region of Upper Silesia since its establishment.

    Opis:
    W artykule przedstawiono stan rynku sprężonego gazu ziemnego jako alternatywnego paliwa do zasilania silników w transporcie, zwrócono uwagę na wymagania dyrektyw Unii Europejskiej oraz obecny stan spełnienia złożonych deklaracji. Zwrócono uwagę na aspekt ekonomiczny i przedstawiono orientacyjne koszty przejechania 10 tys. km na różnych paliwach. Omówiono proces PtG (Power to Gas) wykorzystujący energię elektryczną (produkcja wodoru) oraz ditlenek węgla wychwycony ze spalin bloku węglowego do produkcji syntetycznego metanu. Zaprezentowano schemat instalacji ze wskazaniem jego najistotniejszych składowych, oraz zwrócono uwagę na wzajemne uzupełnianie się technologii PtG z technologią wychwytu ditlenku węgla. Przedstawiono korzyści płynące z produkcji syntetycznego metanu. Opisane zostało zastosowanie sprężonego gazu ziemnego do zasilania silników w pojazdach. Skupiono się na drodze jednopaliwowego zasilania CNG (Compressed Natural Gas) w silnikach autobusów i samochodów ciężarowych, zwracając szczególną uwagę na aspekt ekologiczny zastosowanych rozwiązań. Pokazano, iż stosowanie sprężonego gazu ziemnego pozwoli ograniczyć niemalże o 100% emisję cząstek stałych z procesu spalania. Podano wady i zalety zasilania alternatywnym paliwem. Następnie przeanalizowano aspekt dwupaliwowego zasilania silników wysokoprężnych na przykładzie mniejszego silnika. Pokazano stopień ograniczenia emisji szkodliwych związków z procesu spalania. Na koniec zwrócono uwagę na możliwy efekt skali, powołując się na ilość pojazdów silnikowych w Polsce.
    The article presents the current state of the CNG market used as an alternative fuel for car engines. Attention was paid to European Union directives requirements and the current state of the directives’ fulfillment. The economic aspect of CNG usage was analyzed and the approximate costs of driving 10,000 km on different fuels in the last four years were presented. The PtG process which uses electric energy (hydrogen production) and carbon dioxide captured from the flue gas for the production of synthetic methane were discussed. The scheme of the SNG plant with the indication of its most important components was presented, and attention was paid to the mutual complementation of PtG technologies with carbon dioxide capture technology. The benefits of synthetic methane production are presented and the use of compressed natural gas to power engines in vehicles has been described. First, the focus was on the single-fuel use of CNG in bus and truck engines, paying particular attention to the ecological aspect of the implemented solutions. It has been shown that the use of compressed natural gas will reduce almost 100% of the particulates emission from the combustion process. The advantages and disadvantages of the alternative fuel supply are given. Next, the aspect of dual-fuel use in diesel engines was analyzed on the example of a smaller engine. The degree of reduction of harmful compounds emission from the combustion process is shown. Finally, attention was paid to the possible scale effect, referring to the number of motor vehicles in Poland.

    Opis:
    The Structural Geology and Geohazards Research Group (SRGR) of the Polish Geological Society (PGS) was established in 2017 on the initiative of employees of the Polish Geological Institute - National Research Institute, the University of Wrocław, and the Jagiellonian University in order to integrate structural geologists, exchange views and information, and undertake various forms of cooperation. Geologists from over a dozen Polish scientific and commercial institutions, as well as foreign ones, participate in the works of the section. The activity of the section focuses on improving the research skills of its members and supporting them in achieving the best possible research results. An important element of the section's work is the promotion of issues related to structural research and the dissemination of research results through organizations, and participation in national and international conferences. During the first five years of its activity, the section organized, among others, the 16th CETEG Meeting in 2018 in Rytro (southern Poland), and its members delivered several lectures at conferences organized by PGS and during the “Polish National Scientific Meetings of the Polish Geological Society”, which was organized on the 100th anniversary of the organization's existence.

    Opis:
    Years go by. Time obliterates the memory of people and events that they initiated or inspired. Events, being fruits of efforts made by individuals, frequently driven by fascination, necessity or even chance, build the history of different spheres of social life, and in the case which is of interest to us – of the discipline which is now known as remote sensing. This sketch aims to outline the origin of remote sensing in Poland and the milestones in its development during the past five decades. It does not intend to offer a detailed substantive analysis of various studies, directions of research or numerous practical applications. In the sketch’s final part, the programme of training specialists in geinformatics and remote sensing offered at the University of Warsaw is shortly discussed. In 2009, 45 years passed since the conference of geographers and specialists in aerial photographs interpretation which was held in Warsaw, at the Institute of Geography, Faculty of Biology and Earth Sciences of the University of Warsaw. The conference was organised by the Laboratory of Aerial Photographs Interpretation at the Chair of Regional Geography of the Institute of Geography. The aim of the meeting – which took place in May 1964 – was to familiarise the participants with the findings of research and didactic work at academic centres abroad and at home, in order to develop a new and uniform curriculum for all geography specialisations in Poland. In addition to that, directions of research work conducted by individual laboratories of aerial photograph interpretation were also discussed. The first classes in remote sensing were conducted at geographical studies at the University of Warsaw, specialisation of regional geography, as early as the academic year 1960/1961. Similar classes were also held at the University of Wrocław, Adam Mickiewicz University in Poznań and Maria Curie Skłodowska University in Lublin. In Poland, aerial photography started to be in use from the very first years of independence. In 1921-1924, photoplans on the scale of 1:10 000 covering an area of 3000 km² were made for the Polish-Soviet border areas. 1930 saw the setting up of a specialised enterprise, FOTOLOT. The establishment of the Polish Photogrammetic Society in 1930 was a momentous event as its activity played an important role in the development of photogrammetric methods based on aerial photographs, catering to different needs of the national economy. The most significant achievements in the years 1920-1939 included: a 1931 study by Roman Gryglaszewski, which described the methodology of taking and interpreting aerial photographs for land improvement works on the rivers of the Polesie region, and a 1935 study by Roman Feliński on the analysis of cities, villages and spas in the settlement organisation of the country, in which he highlighted the role of aerial photographs in studies on the country’s spatial development. In 1937-1939, aerial photographs were used in land classification and forestry. We should also mention the work of the Polish geologist Stanisław Zuber, who conducted geological surveys on the Caspian Sea and was a pioneer of using aerial photographs in geology and geotectonic research. In the inter-war period, the Lvov Polytechnic Professor Kasper Weigl, organiser of aerial photography courses, was the most eminent personality in the teaching of remote sensing. Some aerial photographs taken by the German army survived until today from the times of the Second World War; one of such photographs is an aerial photograph of Warsaw taken on 5 August 1944, at the very beginning of the Warsaw Uprising. In it, one can see areas engulfed by fi res and military operations, and the area of the ghetto, razed to the ground, in the form of a light tone. The first aerial photographs after the Second World War were taken already in 1945. The first years after the War, and later, until the end of the 1950s, were not easy for the development of remote sensing in Polish geography despite the systematic character of aerial photography of Poland at the time. In 1957, Bogodar Winid set a long-term plan for himself to change the neutral to negative approach of the geographers’ community to a new research methodology – interpretation of aerial photographs. The plan included familiarisation with the theoretical foundations of photointerpretation, development of materials for this type of classes, gradual training of specialists, gradual introduction of classes in interpretation of aerial photographs for students specialising in regional geography, and later in other specialisations and disciplines, conducting research in this field, and starting cooperation with state bodies and institutions to familiarise them with the socalled “aeromethods”. Looking at this programme fifty years later, we can say that – probably mostly owing to Bogodar Winid’s outstanding drive and energy – this programme was implemented in full. In 1966, interpretation of aerial photographs was made a compulsory subject in geographical studies. To coordinate the development of photointerpretation, on 23 October 1964 a specialised body, the Photointerpretation Committee, was set up as part of the Polish Geographical Society (PTG). A specialised series entitled Fotointerpretacja w geografii [Photointerpretation in geography] was initiated for scientific exchange purposes; currently, it is known as the Teledetekcja Środowiska [Remote sensing] series. By the end of 2008, a total of 40 volumes with 480 papers was published. The Photointerpretation Committee, later transformed into the Remote Sensing Club of the Polish Geographical Society, in the years 1964-2009 organised 19 nation-wide conferences on issues of photointerpretation and remote sensing. The range of remote sensing applications was expanded to other areas ane institutions owing to cooperation with government institutions, as a result of which OPOLIS, the Centre for Processing Aerial Photographs and Satellite Images, was set up as a part of the Institute of Geodesy and Cartography.

    Opis:
    The Gdańsk Branch of the Polish Geological Society was established in 1962. Earlier, geologists from Gdańsk were active within the framework of the Kraków Branch. The number of members of the branch varied over time -from about 30 to over 100 people. The Gdańsk Branch plays an important role in integrating the geological community of the Tri-City. Over 180 lectures were delivered at regular meetings of the branch members. The Gdańsk Branch was also the organizer of several annual meetings of the Society - in 1958,1990 and2002 in Gdańsk, and in 1972 in Cetniewo. The first annual meeting at the seaside took place in 1935 in Gdynia, before the creation of the Gdańsk Branch. The research results presented at the annual meetings showed a continuous progress in geological exploration of the Pomerania region and the Baltic Sea bottom.

    Opis:
    W ostatnim czasie można zaobserwować rosnące zainteresowanie dodawaniem do sieci gazowej wodoru pochodzącego ze źródeł odnawialnych, tzn. technologią power-to-gas. Umożliwia ona przekształcenie wyprodukowanej energii elektrycznej do postaci wodoru i zmagazynowanie go w systemie gazowniczym. Technologia ta może stać się jednym z istotnych czynników zwiększenia udziału energii odnawialnej w całkowitym bilansie energetycznym. Skutkiem dodawania wodoru do gazu ziemnego będzie obecność w sieciach gazowych mieszaniny gazu ziemnego oraz wodoru, która siecią tą docierać będzie do odbiorców końcowych, w tym odbiorców w gospodarstwach domowych. Właściwości fizykochemiczne wodoru, takie jak np. gęstość właściwa czy lepkość, istotnie różnią się od właściwości fizykochemicznych składników gazu ziemnego, takich jak metan, etan, propan, butan, azot itd. W związku z powyższym właściwości mieszaniny gazowej po dodaniu do niej wodoru będą się znacznie różnić od właściwości obecnie stosowanego gazu ziemnego. Tym samym elementy systemu gazowniczego, a także odbiorniki gazu u odbiorców końcowych będą podlegać oddziaływaniu wodoru. Konieczne staje się zatem zapewnienie, że w granicach przewidywanych stężeń wodoru elementy systemu gazowniczego, a także odbiorniki gazu będą w stanie długotrwale pracować bez pogorszenia swych właściwości funkcjonalnych oraz zmniejszenia bezpieczeństwa technicznego. W niniejszym artykule omówiono wyniki dotychczasowych badań prowadzonych w INiG – PIB dotyczących wpływu mieszaniny gazu ziemnego i wodoru na: urządzenia gazowe użytku domowego oraz komercyjnego, rozliczenia i pomiary paliw gazowych, jakość paliw gazowych, gazomierze miechowe oraz reduktory średniego ciśnienia.
    Recently, there has been a growing interest in adding hydrogen from renewable sources to the gas network, i.e. Power-to-Gas technology. This technology makes it possible to convert the produced electrical power into hydrogen and to store it in the gas network. It may become one of the significant factors of increasing the share of renewable energy in the overall energy mix. The addition of hydrogen to natural gas will result in the presence of a mixture of natural gas and hydrogen in the gas networks through which it will reach end users, including household customers. The physicochemical properties of hydrogen, such as specific density or viscosity, differ significantly from those of natural gas components, such as methane, ethane, propane, butane, nitrogen, etc. As a result, the properties of a gas mixture, after adding hydrogen, will be significantly different from those of the natural gas currently in use. Thus, both gas network components and gas appliances of end users will be exposed to hydrogen. It is therefore necessary to ensure long-period operation of gas network components and gas appliances, within the limits of anticipated hydrogen concentrations, without deterioration in their functional properties and technical safety. This paper discusses the results of research conducted at INiG – PIB in terms of resistance to a mixture of natural gas and hydrogen (up to 23%) on: gas appliances for household and commercial use, gaseous fuels metering and billing, gaseous fuels quality, diaphragm gas meters and medium pressure regulators.

    Opis:
    Since 2016, Oil and Gas Institute – National Research Institute (INiG – PIB) has been conducting new research to determine the relationship between ambient temperature and gas temperature in industrial diaphragm gas meters during the measurement, and to develop new recommendations for billing systems using industrial diaphragm gas meters with a throughput of until 25 m3 /h. In the first stage, work was carried out, in which the obtained test results confirmed that the heat exchange process in an industrial diaphragm gas meter depends on the ambient temperature, the gas temperature at the inlet to the gas meter, the flow rate of the gas flowing, as well as the casing surface and the gas volume of the gas meter. In the next stage, work was carried out to determine the relationship between ambient temperature and gas temperature at the industrial diaphragm gas meter connection during the measurement. The obtained results undermined the thesis, which indicated that the gas inlet temperature is equal to the gas temperature at the depth of the gas network. In the last stage, work was carried out to determine the course of changes in gas temperature in industrial diaphragm gas meters as a function of ambient temperature and cyclical changes of the gas flow rate, which were to reflect the work of gas meters installed at customers’ premises. The analysis of the obtained test results once again showed a strong dependence of the gas temperature inside industrial diaphragm gas meters on the ambient temperature, but also on the flow rate of gas. The obtained results of laboratory tests will be used to carry out a thermodynamic description of the heat exchange process in an industrial diaphragm gas meter, which would allow the determination of the gas billing temperature as a function of the ambient temperature, the temperature of the inflowing gas and the gas flow rate. The calculated gas temperature values could be used to determine the temperature correction factors applicable when settling gas consumers billed on the basis of measurement with the use of industrial diaphragm gas meters.
