Opis:
Pozyskiwanie energii elektrycznej jest istotnym wyzwaniem XXI wieku. Na świecie w elektroenergetycznych projektach cywilnych coraz silniej dominują tendencje proekologiczne: energia wiatru, promieniowania słonecznego i energia elektryczna z tzw. baterii wodorowych i ich mutacji. W zastosowaniach wojskowych wykorzystanie tego typu źródeł również jest korzystne, gdyż znacznie poprawia możliwości maskowania, m.in. umożliwia zmniejszenie poświaty termicznej i natężenia hałasu. Autorzy artykułu opracowali przegląd ekologicznych systemów zasilania oraz przedstawili aktualny stan wdrożeń.
Obtaining electrical energy is a substantial challenge for the 21st century. The world is increasingly dominated by pro-ecological tendencies: wind energy, solar radiation and electric energy from the so-called hydrogen batteries and their mutations. In military applications, using these source types is also beneficial since it substantially improves camouflage possibilities, e.g., it enables the reduction of the thermal afterglow and noise intensity. The manuscript’s authors developed the overview of pro-ecological power systems and presented the current state of implementations.

Opis:
In 2018 during the 72nd session of the Maritime Environmental Protection Committee (MEPC) IMO adopted its initial strategy for the reduction of greenhouse gas emissions (GHG) from the ships to meet the Paris Agreement Goals, 2015. This is considered as a major milestone in formulizing a clear strategy by IMO towards its objective of reducing the global GHG emissions from the ships. The strategy had two primary objectives: the first was to decrease total annual GHG emissions by at least 50% by 2050 compared to 2008 levels. The second objective was to promote the phasing out of GHG emissions entirely. In 2020, the International Maritime Organization (IMO) conducted a study which revealed that greenhouse gas (GHG) emissions from shipping had increased by 9.6%. The rise in global maritime trade was identified as the main factor behind this increase. IMO's 2020 study also concluded that reducing GHG emissions by focusing only on energy-saving technologies and ship speed reduction would not be enough to meet the IMO's 2050 GHG reduction target. Therefore, greater attention needs to be given to the use of low-carbon alternative fuels. To understand the effectiveness of currently available technologies in reducing GHG emissions from ships, a literature survey was conducted in this study. The survey examined a range of related articles published between 2018 and 2022. This study aimed to identify the current stage and the quantity of literature available on various technologies and, more importantly, serve as a decision-making support tool for selecting a technology under specific circumstances in a quantitative manner. The technologies were divided into four groups: those that utilize fossil fuels, those that use renewable energy, those that use fuel cells, and those that use low-carbon or alternative fuels. The literature survey was conducted using Web of Science (WoS) and Google Scholar. The results of this study will also help to identify clear research gaps in comparing the effectiveness of various available technologies to reduce GHG emissions. Ultimately, the aim is to develop a comprehensive strategy that can be used to reduce GHG emissions from shipping and contribute to the global fight against climate change.

Opis:
A hybrid energy system (HES) including hydrogen fuel cell systems (FCS) and a lithium-ion (Li-ion) battery energy storage system (ESS) is established for hydrogen fuel cell ships to follow fast load transients. An energy management strategy (EMS) with hierarchical control is presented to achieve proper distribution of load power and enhance system stability. In the high-control loop, a power distribution mechanism based on a particle swarm optimization algorithm (PSO) with an equivalent consumption minimization strategy (ECMS) is proposed. In the low-level control loop, an adaptive fuzzy PID controller is developed, which can quickly restore the system to a stable state by adjusting the PID parameters in real time. Compared with the rule-based EMS, hydrogen consumption is reduced by 5.319%, and the stability of the power system is significantly improved. In addition, the ESS degradation model is developed to assess its state of health (SOH). The ESS capacity loss is reduced by 2% and the daily operating cost of the ship is reduced by 1.7% compared with the PSO-ECMS without considering the ESS degradation.

Opis:
Many new zero-emission propulsion technologies are being developed today due to the need to reduce the atmospheric carbon dioxide emissions. The impact of the transport sector on the environment drives a need for innovation, including innovation in the rail transport sector specifically. At the TRAKO fair of rail vehicles the newest technological solutions have been presented. These new vehicles are expected to take over the rail transport sector in the coming decades. Many of the presented solutions and prototypes focused on using hydrogen as fuel for a system of hydrogen fuel cells, which are then used to produce the electricity needed to drive the vehicle. The development of hydrogen fuel technologies in vehicle drives in recent years allowed for a set of new solutions to appear for all types of rail vehicles and applications. Hydrogen powered rail vehicles for transporting cargo, passengers, and shunting vehicles have been shown. This article provides a discussion of the newest hydrogen solutions and vehicles sent to the market. It was determined that the adoption of such solutions will be mainly restricted by the relative cost of the hydrogen fuel rather than the vehicles or fuel cell technologies themselves. The cost of hydrogen production, when powered by renewable Energy sources to enable reduced carbon dioxide emissions, would need to be reduced to at least $2.50 /kg of fuel in order to satisfy the requirements for widespread adoption.

W artykule scharakteryzowano podstawowe warianty wykorzystania wodoru jako magazynu i nośnika energii, a także ogniw paliwowych w energetyce rozproszonej. Przedstawiono możliwości integracji rozwiązań technologii wodorowych i ogniw paliwowych z odnawialnych źródeł energii w systemach niezależnego zasilania dla budownictwa. Wodór wytwarzany w procesie elektrolizy może być magazynowany w skalowalnych zbiornikach wysokociśnieniowych (200–350 barów) oraz w niskociśnieniowych magazynach wodoru, a następnie wykorzystany do produkcji energii elektrycznej z ogniw paliwowych. Interesującą opcją jest również wykorzystanie alternatywnych paliw (np. metanolu) jako nośników wodoru do budowy pomocniczych układów zasilania w budownictwie. Kolejną ważną cechą rozważanych układów rozproszonych jest możliwość uzyskania wariantowego ciepła, zarówno z ogniw paliwowych, jak i w procesach wodorowych.
The article describes the main options for using hydrogen as an energy storage and carrier, and for using fuel cells in distributed energy. It presents the possibilities of integrating hydrogen and fuel cell technology solutions with renewable energy sources in independent power systems for the building industry. Hydrogen produced by electrolysis can be stored in scalable high-pressure (200–350 bar) and low-pressure hydrogen storage tanks and then used to generate electricity from fuel cells. The use of alternative fuels (e.g. methanol) as hydrogen carriers for auxiliary power systems in building industry is also an interesting option. Another important feature of the distributed systems under consideration is the possibility of recovering and using waste heat, both from fuel cells and hydrogen processes.

Opis:
Among the possible electric powerplants currently driving low-payload UAVs (up to around 10 kg of payload), batteries offer certain clear benefits, but for medium-payload operation such as aerotaxis and heavy-cargo transportation UAVs, battery capacity requirements restrict their usage due to high weight and volume. In light of this situation, fuel cell (FC) systems (FCS) offer clear benefits over batteries for the medium-payload UAV segment (> 50 kg). Nevertheless, studies regarding the application of FCS powerplants to this UAV segment are limited and the in-flight performance has not been clearly analysed. In order to address this knowledge gap, a feasibility analysis of these particular applications powered by FCS is performed in this study. A validated FC stack model (40 kW of maximum power) was integrated into a balance of plant to conform an FCS. As a novelty, the management of the FCS was optimized to maximize the FCS efficiency at different altitudes up to 12500 ft, so that the operation always implies the lowest H2 consumption regardless of the altitude. In parallel, an UAV numerical model was developed based on the ATLANTE vehicle and characterized by calculating the aerodynamic coefficients through CFD simulations. Then, both models were integrated into a 0D-1D modelling platform together with an energy management strategy optimizer algorithm and a suitable propeller model. With the preliminary results obtained from the FCS and UAV models, it was possible to ascertain the range and endurance of the vehicle. As a result, it was concluded that the combination of both technologies could offer a range over 600 km and an endurance over 5 h. Finally, with the integrated UAV-FCS model, a flight profile describing a medium altitude, medium endurance mission was designed and used to analyse the viability of FC-powered UAV. The results showed how UAVs powered by FCS are viable for the considered aircraft segment, providing competitive values of specific range and endurance.

The article presents the situation regarding the hydrogenisation of motor transport in Northwestern Europe, a region leading in this regard in Europe. The following countries were included in the analysis of national plans in this area, taking into account both technical issues - among others - concerning HRS and FCEV, their number, as well as economic issues (among other things relating to the costs of using hydrogen): Belgium, Denmark, France, Germany, the Netherlands, Norway and England. Reference was also made to the situation in Poland, where major fuel and energy companies (among others: Orlen, Lotos, PGNiG and ZE PAK Capital Group) are strongly interested in hydrogenisation of motor transport and manufacturers of vehicles - for example - Solaris or Autosan in producing vehicles equipped with fuel cells. Based on the analyses carried out at the Institute of Motor Transport, it was found that the good location of basic hydrogen refuelling stations is along the TEN-T corridors running across Poland. The order of their location is as follows: 1 - Poznan, 2 - Warsaw,3 - Bialystok, 4 - Szczecin, 5 - Łódź region, 6 - Tricity, 7 - Wroclaw, 8 - Katowice region, 9 - Kraków.

W artykule przedstawiono tematykę zagospodarowania wodoru w kontekście polityk krajowych (np. Porozumienie sektorowe na rzecz rozwoju gospodarki wodorowej w Polsce) i unijnych (pakiet aktów prawnych „Fit for 55”). Jednym ze sposobów wykorzystania wodoru do produkcji energii elektrycznej lub cieplnej jest technologia ogniw paliwowych. Umożliwia ona wytwarzanie ww. energii bez emisji szkodliwych substancji, np. pyłów. W dalszej części artykułu przedstawiono stan ogniw paliwowych w Polsce. Omówiono, jakie projekty i działalności podejmują polskie jednostki na rzecz rozwoju technologii ogniw paliwowych w Polsce. Następnie scharakteryzowano rynek urządzeń dla użytkowników domowych. Obecnie rynek tego typu urządzeń dla gospodarstw domowych jest stosunkowo mały. W katalogach producentów znajdują się agregaty prądotwórcze oraz kogeneratory lub mikrokogeneratory. Krótko omówiono dostępne urządzenia: jakie ogniwa paliwowe wykorzystują, jakim rodzajem paliwa są zasilane, jakie są ich parametry eksploatacyjne (tj. moc cieplna, moc elektryczna, sprawność). W dalszej części artykułu przedstawiono sposoby wprowadzania produktów na rynek Unii Europejskiej. Jeśli ogniwa paliwowe i urządzenia je wykorzystujące mają być dopuszczone do obrotu w Unii Europejskiej, muszą spełniać wymagania odpowiednich rozporządzeń i dyrektyw. Wymieniono rozporządzenia i dyrektywy, którym mogą podlegać urządzenia wykorzystujące ogniwa paliwowe. Następnie przedstawiono zagadnienia związane z certyfikacją i badaniami potwierdzającymi właściwości deklarowane dla urządzeń z ogniwami paliwowymi w Laboratorium Badań Urządzeń Gazowych i Grzewczych Instytutu Nafty i Gazu – Państwowego Instytutu Badawczego. Omówiono zagadnienia związane z zakupem generatora energii elektrycznej wykorzystującego stos ogniw paliwowych, a także konfigurację stanowiska pomiarowego przygotowanego na potrzeby prowadzenia badań realizowanych w ramach pracy statutowej. Podano, jakie instalacje oraz ich opomiarowanie są konieczne do prowadzenia badań. Po stronie zasilającej urządzenia z ogniwem paliwowym znajdują się: paliwo, utleniacz (np. powietrze), energia elektryczna potrzebna do rozruchu urządzenia, natomiast po stronie wyjścia: energia elektryczna i cieplna produkowana przez urządzenie, gazy wylotowe oraz woda.
The article presents the topic of hydrogen management in the context of national (Sectoral agreement for the development of the hydrogen economy in Poland) or EU policies (the document “Fit for 55”). Possible way of using hydrogen to produce electricity or heat is through fuel cell technology. It enables the production of the above-mentioned energy without the emission of harmful substances, e.g. particulate matter. The further part of the article presents the state of art of fuel cells in Poland. The projects and activities undertaken by Polish organization for the development of fuel cell technology in Poland were discussed. Then, the household appliances market was characterized. Currently, the market for this type of appliances is relatively small. Manufacturers' catalogues include power generators and cogenerators or micro-cogenerators. The available devices were briefly discussed: what fuel cells they use, what kind of fuel they are powered by, their operational parameters are given (thermal power, electric power, efficiency). The further part of the article presents the ways of introducing products to the European Union market. If fuel cells and devices that use them are to be marketed in the European Union, they must comply with the relevant regulations and directives. The regulations and directives that fuel cell equipment may be subject to were listed. The issues related to certification and tests confirming declared properties of appliances with fuel cells at the Gas and Heating Equipment Test Laboratory of the Oil and Gas Institute – National Research Institute were presented. The purchase of an electric energy generator using a stack of fuel cells, as well as the configuration of a measuring stand, prepared for the needs of research carried out under the statutory work, were discussed. It was indicated which installations, along with their metering, are necessary for the research. On the supply side of a fuel cell device there is: fuel, oxidant (e.g., air), electricity needed to start the device, while on the output side: electricity and heat produced by the device, exhaust gases and water.

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.

Ogniwa paliwowe nie są technologią nową, ale zyskują na popularności i są intensywnie rozwijane. W artykule przedstawiono i scharakteryzowano różne rodzaje ogniw paliwowych będących obecnie w kręgu zainteresowania ośrodków naukowo-badawczych zajmujących się problematyką ochrony środowiska naturalnego. Są to ogniwa paliwowe typu: alkaliczne (AFC, ang. alkaline fuel cell), z kwasem fosforowym (PAFC, ang. phosphoric acid fuel cell), stałotlenkowe (SOFC, ang. solid oxide fuel cell), ze stopionym węglanem (MCFC, ang. molten carbonate fuel cell), z membraną do wymiany protonów (PEMFC, ang. proton exchange membrane fuel cell), w tym ogniwo zasilane bezpośrednio metanolem (DMFC, ang. direct methanol fuel cell). Porównano parametry pracy wymienionych ogniw paliwowych oraz opisano zasadę ich działania. Rosnące zainteresowanie urządzeniami wykorzystującymi wodór jako paliwo wynika również z rozwoju technologii power-to-gas (P2G). Ponadto w artykule przedstawione zostały potencjalne kierunki rozwoju i możliwości wykorzystania ogniw paliwowych w różnych dziedzinach i sektorach gospodarki. Ogniwa paliwowe mogą znaleźć zastosowanie np. w transporcie. Przedstawiono charakterystykę pojazdów samochodowych używanych w Unii Europejskiej, a także specyfikację techniczną samochodów osobowych komercyjnie dostępnych wykorzystujących ogniwa paliwowe z membraną do wymiany protonów. Omówiono możliwość użycia ogniw paliwowych w transporcie zbiorowym (autobusy, pociągi). Przedstawiono możliwości pracy ogniw paliwowych w układach skojarzonych (wytwarzających energię elektryczną i ciepło na cele grzewcze i/lub chłodnicze). Rozważono wykorzystanie technologii ogniw paliowych w dużych jednostkach kogeneracyjnych oraz w układach mikro. Jednym z przedstawionych układów kogeneracyjnych jest połączenie ogniw paliwowych z turbiną gazową. Innym sposobem wykorzystania ogniw paliwowych jest magazynowanie energii w systemach EES. Interesującym rozwiązaniem mogą być również systemy power-to-power, które także zostały krótko scharakteryzowane.
Fuel cells are not a new technology, but they are gaining in popularity and are being intensively developed. The article presents and characterizes various types of fuel cells that are currently of interest to research and development centers dealing with environmental protection issues. These include: alkaline fuel cell (AFC), phosphoric acid fuel cell (PAFC), solid oxide fuel cell (SOFC), molten carbonate fuel cell (MCFC), proton exchange membrane fuel cell (PEMFC), including direct methanol fuel cell (DMFC). The operating param- eters of the previously mentioned fuel cells were compared. The principle of operation of a fuel cell was described. The growing interest in devices using hydrogen as a fuel also results from the development of Power to Gas technology (P2G). Furthermore, the article presents the potential directions of development and use of fuel cells in various fields and sectors of the economy. Fuel cells can be used in transport. The characteristic of motor vehicles fleet by fuel type in usage in the European Union was presented. The technical specification of commercially available passenger cars using fuel cells with proton exchange membrane was presented. The possibility of using fuel cells in public transport (buses, trains) was discussed. The possibilities of operation of fuel cells in combined heat and power systems (CHP) were presented. Usage of fuel cell technology in large cogeneration units and micro systems was considered. One of the presented cogeneration systems is a combination of fuel cells with a gas turbine. Another possibility of using fuel cells is energy storage systems (EES). Interesting way of using fuel cells can also be Power to Power systems, which were briefly characterized.

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:
Renewable energy application is gaining a wide acceptance by end users; however, considering the fact that renewable energy is intermittent, variable and cannot be predicted, the need of storage systems is becoming a necessity at both micro and macro levels. Fuel cell technology is one of the most promising storage systems due to the fact that hydrogen has high energy density. This paper presents a design of stand-alone PV-PEMFC hybrid system for a small house under Amman climate. The simulation results show that the optimal size of PV array, fuel cell (PEMFC), inverter, electrolyzer (ELE) and H2 Tank capacity were 10 kW, 1 kW, 5 kW, 6 kW, and 5 kg respectively. Hydrogen proved itself as a low carbon energy source, which is environmental friendly and characterized with high energy content per unit mass. Due to fuel cells technology, hydrogen can be used for inter-season storage.

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.
