Opis:
According to (McKinsey & Company, 2020), drilling and extraction operations are responsible for 10% of approximately 4 billion tons of CO2 emitted yearly by Oil and Gas sector. To lower carbon emissions, companies used different strategies including electrifying equipment, changing power sources, rebalancing portfolios, and expanding carbon-capture-utilization-storage (CCUS). Technology evolution with digital transformation strategy is essential for reinventing and optimizing existing workflow, reducing lengthy processes and driving efficiency for sustainable operations. Details subsurface studies take up-to 6–12 months, including seismic & static analysis, reserve estimation and simulation to support drilling and extraction operations. Manual and repetitive processes, aging infrastructure with limited computing-engine are factors for long computation hours. To address subsurface complexity, hundred-thousand scenarios are simulated that lead to tremendous power consumption. Excluding additional simulation hours, each workstation uses 24k kWh/month for regular 40 hours/month and produces 6.1kg CO2. Machine Learning (ML) become crucial in digital transformation, not only saving time but supporting wiser decision-making. An 80%-time-reduction with ML Seismic and Static modeling deployed in a reservoir study. Significant time reduction from days-tohours-to-minutes with cloud-computing deployed to simulate hundreds-thousands of scenarios. These time savings help to reduce CO2-emissions resulting in a more sustainable subsurface workflow to support the 2050 goal.

Opis:
This paper investigates the relation between the prices of CO2 emission allowances in the EU ETS (Emission Trading System) and wholesale prices of electricity in Poland. Linear regression models were used to assess carbon price pass-through rate to wholesale electricity prices during the entire III phase of ETS (2013-2020). It has been found that the entire cost of CO2 emission allowances was included in the wholesale electricity price. As expected, the peak transmission parameter is higher than the off-peak one. Nevertheless, the difference is small and statistically insignificant. Hence the model does not allow for any far-reaching conclusions in this regard. Results show that electricity producers were able to pass the entire emission-related costs to the customers, which might raise a question of whether EU ETS is an effective tool to give sufficient incentives to decarbonise electricity production.
W artykule zbadano zależność pomiędzy cenami uprawnień do emisji gazów cieplarnianych w systemie EU ETS (unijny system handlu uprawnieniami do emisji), a hurtowymi cenami energii elektrycznej w Polsce. Wykorzystano modele regresji liniowej do oszacowania parametru transmisji cen uprawnień do emisji na hurtowe ceny energii elektrycznej podczas III fazy EU ETS (2013-2020). Wyniki modelowania wykazały, że cały koszt uprawnień do emisji CO2 był uwzględniany w hurtowej cenie energii elektrycznej. Zgodnie z oczekiwaniami szczytowy parametr transmisji okazał się wyższy niż pozaszczytowy, niemniej jednak różnica jest niewielka i statystycznie nieistotna, model nie pozwala więc na wyciąganie daleko idących wniosków w tym zakresie. Wyniki pokazują, że producenci energii elektrycznej byli w stanie przerzucić całość kosztów związanych z emisjami na odbiorców, co może rodzić pytanie, czy EU ETS jest skutecznym narzędziem dającym wystarczające zachęty do dekarbonizacji produkcji energii elektrycznej.

Opis:
An analysis of the methods used in Bulgaria for estimating CO2, SO2 and dust emissions has been conducted. The first methodology, which is officially used by all energy auditors at the Agency for Sustainable Energy Development targets the energy efficiency of combustion devices installed mainly at industrial enterprises. The second methodology, used by the Ministry of Environment and Water, is more comprehensive and can be applied to thermal power plants, small combustion plants as well as industrial systems. In recent years, many projects related to energy efficiency and renewable energy projects, including hydrogen technologies, which require an assessment of reduced greenhouse gas emissions, have been implemented as a priority. The use of reliable and accurate methods is essential in the assessment of greenhouse emissions. A novel methodology, based on stoichiometric equations of the combustion process for solid, liquid and gaseous fuels has been proposed and comprised. This novel methodology is characterized by higher precision compared to the methods currently in place and this is achieved through calculating emissions from the combustion of energy fuels accounting for the full elemental composition of the fuel and its heating value, whereas the current commonly applied methods use only the fuel type and the carbon content. A further benefit of the proposed methodology is the ability to estimate emissions of fuels for which there is no alternative method for calculating CO2, SO2 and dust. Results of emission calculations according to the analysed methods are presented. Finally, a comparative analysis between the presented methodologies including an assessment of their accuracy and universal applicability has been made.

Opis:
Poland is a participant to the European Union Emissions Trading System, which aims at reducing greenhouse gas emissions. Trading CO2 emission rights has become a strategic area from the point of view of managing entities that emit CO2. The aim of the paper is to investigate and identify discrepancies in the presentation and valuation of CO2 emission allowances, CO2 emission provision liabilities in reporting, and to assess the impact of these discrepancies on compliance with the true and fair view principle on top of the informative value of the financial statements. An in-depth qualitative analysis was used to examine disclosures of CO2 emission rights in the 2020 consolidated financial statements coming from the largest energy sector groups listed in the WIG Energy Index of the Warsaw Stock Exchange in light of the relevant legal acts and literature. As a result of the research conducted, it was confirmed that groups of companies carry out a range of CO2 emission rights balance classification and valuation. There were also significant discrepancies in the disclosure of information about the creation and valuation of provisions for liabilities due to CO2 emissions. The discrepancies observed in the audited entities’ balancesheet presentations and valuation of the acquired CO2 emission allowances and reserves resulting from IAS/IFRS in practice distorts the comparability of data presented in the financial statements. The research also revealed differences in scope of disclosed information, as well as its fragmentary nature. As a result, the comparison of data between groups in the energy sector in terms of their assets is impossible. Our study fills a research gap on the effects of using IFRS for the presentation and valuation of CO2 emission rights in the Polish energy sector and the impact of a differentiated approach to disclosures on the true and fair view conception in financial reporting.

In terms of climate forecasting, the Mediterranean region is among the most difficult. It is correlated with the five significant subtropical high pressure belts of the oceans and is symbolized by dry and hot summer and cold and rainy winter. Due to its location in the area, Albania is particularly susceptible to climatic changes. It has been noted that summertime sees the greatest temperature increases. More intense heat waves that stay longer and occur more frequently are anticipated in the eastern Mediterranean. The seasonal patterns of precipitation have not changed, but the amount of rain has become more intense. The effects of climate change have drawn attention to various renewable energy sources, including solar and wind power. In this study, the changes and prospective in average temperature, rainfall, humidity, CO2 emission and their impact in energy production were investigated. Several different models such as Auto Regressive Integrated Moving Average method; Prophet algorithm; Elastic-Net Regularized Generalized Linear Model; Random Forest Regression models; Prophet Boost algorithm; have been built for the study and prediction of each variable. The appropriate models are used to determine the anticipated values of the indicators for a period of four years. The prediction shows an increase in CO2 emission which leads to a decrease in energy production by hydropower. These findings suggest the use of other renewable sources for energy production in the country and the Mediterranean region.

Opis:
The aim of this study is to investigate how the daily electricity demand from road transport related to the implementation of an electric road system on the eight roads with the highest traffic flow connecting the seven largest cities in Turkey varies according to time and location. Intercity highway route O-7, O-5, O-21, D715, D687, E96, and E87 in Western Turkey was used as a case study. The daily electricity demand on the eight roads working on the full electrification of the existing traffic flow can be increased by 3.7% in the case of the reference point. However, if all roads in Turkey are converted to an electric road system and all land vehicles use this system, the corresponding peak power increase will be 100%. The daily electricity demand along the roads is derived from the available measuring points for the daily road traffic volumes. The study also compares the CO2 reduction potentials and energy demands of the electrified road system with the use of fossil fuels to achieve the same transportation volume. The results show that an electric road system application on eight Turkish roads with considerable traffic flow can reduce 18.8 million tons of CO2 emissions from the road transport sector. The research can find practical application in assessing the validity of developing a strategy for the development of electromobility on highways in Turkey.
Celem tego artykułu jest zbadanie, w jaki sposób dobowe zapotrzebowanie na energię elektryczną w transporcie drogowym związane z wdrożeniem elektrycznego systemu drogowego na ośmiu drogach o największym natężeniu ruchu, łączących siedem największych miast w Turcji, zmienia się w zależności od czasu i lokalizacji. Jako studium przypadku wykorzystano autostradę międzymiastową O-7, O-5, O-21, E96 i E87 w zachodniej Turcji. Dobowe zapotrzebowanie na energię elektryczną na ośmiu drogach pracujących nad pełną elektryfikacją istniejącego ruchu może w przypadku punktu odniesienia wzrosnąć o 3,7%. Jeśli jednak wszystkie drogi w Turcji zostaną przekształcone w elektryczny system drogowy i wszystkie pojazdy lądowe będą korzystać z tego systemu, odpowiedni wzrost mocy szczytowej wyniesie 100%. Dobowe zapotrzebowanie na energię elektryczną wzdłuż dróg pochodzi z dostępnych punktów pomiarowych dobowego natężenia ruchu drogowego. Badanie porównuje również potencjały redukcji CO2 i zapotrzebowanie energetyczne zelektryfikowanego systemu drogowego z wykorzystaniem paliw kopalnych w celu osiągnięcia tej samej wielkości transportu. Wyniki pokazują, że zastosowanie elektrycznego systemu drogowego na ośmiu tureckich drogach o znacznym natężeniu ruchu może zmniejszyć emisję CO2 o 18,8 mln ton z sektora transportu drogowego. Badania mogą znaleźć praktyczne zastosowanie w ocenie zasadności opracowania strategii rozwoju elektromobilności na autostradach w Turcji.

Opis:
Cruising tourism is becoming increasingly popular, the number of cruises having seen a continuous increase since the 1970s. In Croatia as well there is an upward trend in the number of cruise passengers and ports. Of all Croatian ports, it is the port of Dubrovnik that has had the most calls by foreign cruisers. The paper analyses the available statistical data on the maritime cruise market in Europe with special reference to the Mediterranean countries. In the national context, a presentation of cruise traffic in the port of Dubrovnik is given. Although this type of tourism contributes to the development and improvement of the economy, it also has a negative impact on the environment through air pollution by CO2 emissions, subsequently affecting human health as well. The authors investigate the level of CO2 emissions in the area of the port of Dubrovnik. CO2 emissions were calculated based on cruiser activity, the calculations being based on CO2 emissions for three ship navigation modes - slow steaming on arrival and departure, manoeuvring on arrival and departure, and for a berthed ship. The aim of the research was to provide a better insight in the emission inventories in this area. This research can also be applied to other port areas.

W artykule poruszono zagadnienia związane z modelowaniem emisji spalin z wykorzystaniem mikroskopowych symulacji ruchu drogowego. Celem pracy było opracowanie modelu ruchu, na podstawie którego możliwe jest obliczenie emisji z pojazdów z uwzględnieniem typu skrzyżowania oraz wartości natężeń ruchu. W artykule skupiono się na wartościach zużycia paliwa i emisji dwutlenku węgla. Przeanalizowano literaturę w zakresie czynników wpływających na emisję, które zależne są od człowieka, pojazdu i infrastruktury. Dokonano przeglądu matematycznych modeli pozwalających na obliczenie wartości chwilowych, często związanych ze zużyciem paliwa, które stanowią podstawę do oszacowania emisji. Wybrany model został zaimplementowany do modułu oprogramowania mikrosymulacyjnego w celu analizy wielkości emisji, w zależności od natężenia ruchu na skrzyżowaniu o ruchu okrężnym i skrzyżowaniu z pierwszeństwem przejazdu. Przedstawiono wyniki badań z uwzględnieniem wariantów modeli sieci obejmujących jedynie dojazd i przejazd przez skrzyżowanie oraz niezależnie uwzględniających rozpędzanie pojazdów za skrzyżowaniem. W końcowym fragmencie artykułu objęto dyskusją wybrane założenia, możliwe do uwzględnienia w analizach i mające wpływ na osiągnięte wyniki, omówiono kwestie dokładności modelu oraz zaproponowano rozwiązania pozwalające na zwiększenie poziomu szczegółowości osiąganych wyników.
The article deals with issues related to modeling of exhaust emissions using microscopic traffic simulations. The aim of the study was to develop a traffic model that can be used to calculate vehicle emissions taking into account the type of intersection and traffic volumes. The article focuses on fuel consumption and carbon dioxide emission values. The literature was analyzed for factors affecting emissions that depend on human, vehicle, and infrastructure. Mathematical models were reviewed to calculate instantaneous values, often related to fuel consumption, which form the basis for estimating emissions. The selected model was implemented in a microsimulation software module to analyze emissions as a function of traffic volume at a roundabout intersection and a priority intersection. The results are presented for variants of network models that include only the approach and crossing of the intersection and those that independently account for vehicle acceleration beyond the intersection. The final part of the article discusses the selected assumptions that can be taken into account in the analyses and have an impact on the results obtained. It also discusses the issues of model accuracy and proposes solutions that enable an increase in the level of detail of obtained results.

Opis:
Negative Emission Technologies (NETs) are generally considered as vital methods for achieving climate goals. To limit the rise in the global average temperature below 2°C, a large number of countries that participated in the Paris agreement was virtually unanimous about the effective collaboration among members for the reduction of CO2 emissions throughout this century. NETs on the ground that can remove carbon dioxide from the atmosphere, provide an active option to achieve this goal. In this contribution, we compare limiting factors, cost, and capacity of three different NETs, including bioenergy with carbon capture and storage (BECCS), absorption and adsorption. Although there are several advantages for capturing CO2, still some constraints regarding the high operational cost of NETs and industrial condition of these technologies as a method of climate change mitigation is not clear. Thereby no single process can be considered as a comprehensive solution. Indeed, any developed technologies, in turn, have a contribution to the reduction of CO2 concentration. Extensive research needs to be done to assess and decrease NETs costs and limitations.

Opis:
Decarbonisation of the European economy is one of the most important megatrends that will shape economic and social development in the coming years. This paper discusses the basic concepts of decarbonisation in terms of climate change, the history of this idea development and the legal basis introduced in the European Union, including key European documents and tools influencing the process, like ETS or CO2 emission allowances. Background on decarbonisation has been presented as a European roadmap to achieve a low-carbon economy in Europe. In the article the main assumptions of the EU strategy papers like Clean Energy for All Europeans or the European Green Deal are presented. Casus Silesia indicates the basic problematic issues that coal regions will have to tackle to due to the transition away from coal. For European societies, the new environmental policy of the European Commission means the intensification of activities to reduce greenhouse gas emissions and switching the economy to low- or zero-carbon energy sources and technologies. The decarbonisation of the economy is an ongoing process which has been gaining momentum in recent years. The coal transition is a huge challenge, particularly for Poland.

Opis:
Vehicle exhaust emissions depend on multiple factors, such as the emission norm, driving parameters (speed, acceleration) or the technical condition of the vehicle. These driving parameters may often depend on the condition of the road infrastructure and other factors influencing road conditions. The article attempted to assess the emissivity during acceleration of a vehicle powered by a compression ignition engine. Mapping the actual values is possible with the use of exhaust emission measurement equipment that operates under the actual operating conditions of a vehicle. Recently, an increase in the use of simulation methods in research of this type has been observed. The authors decided to check the suitability of using road traffic simulation software to estimate the $CO_2$ emissions during vehicle acceleration. The obtained results are promising, because in terms of the emissions of the analyzed exhaust gas component, the simulation results differed from the results obtained during measurements with the use of Portable Emissions Measurement System (PEMS) equipment by less than ±20%.

Opis:
The energy sector worldwide is a significant source of air pollutant emission. In Poland, the vast majority of heat and electricity is generated in coal-fired heat and power plants. There is a common belief that high greenhouse gas emissions from the energy sector in Poland are mainly due to the technological processes involving the conversion of energy by burning fossil fuels. However, coal mining also causes a high environmental burden. This paper aimed to determine the carbon footprint of a typical hard coal-fired heating plant in Poland, taking into account mining of hard coal, its transport to the heating plant and useful energy generation in the heating plant. The investigation carried out allowed comparing the process steps and determining which of them is the dominant source of the greenhouse gas emissions. The obtained results show that hard coal mining and hard coal transport account for almost 65% and 5% of total equivalent carbon dioxide emission, respectively. Energy transformations in the heating plant account for 30% of total equivalent carbon dioxide emission, where approx. 29% is due to hard coal burning and 1% due to electricity consumption. The relative shares of carbon dioxide, methane and nitrous oxide in total equivalent carbon dioxide emission account for approx. 91%, 4% and 5%, respectively.
