Over the past few decades, the liquefied natural gas (LNG) business has experienced astounding expansion and gained global relevance. LNG has emerged as a key element in meeting the world's rising energy demand while working to cut carbon emissions, since it is a cleaner and more adaptable energy source. The entire process from natural gas extraction to consumption is covered in the presented analysis of the LNG value chain, starting out by looking at the discovery and production of natural gas reserves, highlighting important innovations and methods used during the extraction stage. The procedures used to treat and purify natural gas in order to meet the strict standards for liquefaction are detailed. Analysis of the liquefaction process reveals numerous liquefaction technologies, e.g. the well‐known conventional liquefaction and the cutting‐edge floating LNG and small‐scale LNG facilities. LNG storage and transportation, as critical components in the value chain, are examined in great detail. When the LNG reaches its destination, regasification plays a crucial role in repurposing it as a gas for distribution and consumption. Regasification technologies, such as conventional onshore terminals, floating storage and regasification units, and land‐based regasification facilities, are covered. Concerns regarding methane emissions and the carbon footprint, the potential for reducing greenhouse gas emissions through new technology, the environmental impact of LNG, and the economics of LNG are also considered across its value chain.

The problems of worldwide environmental degradation, global warming, scarcity of fossil fuels hascaused the replacement of ICE vehicles with electric ones. For the countries with underdeveloped economy, it is important to find more affordable ways to solve this problem. One of them is to convert the cars with ICE into more environmentally friendly and economical ones, such as gas-powered cars. Yet, the conversion of diesel cars usually results in power loss. The work of the electromagnetic gas dispenser (EGD) of the engine power supply system significantly affects the efficiency of the gas engine. Therefore, the aim of the study was to determine the dynamic and flowcharacteristics of the EGD of the KrAZ truck (Ukraine) converted to gas, and to provide recommendations for improving the efficiency of its operation. The object of the research was the working processes of the EGD power supply system of 6ChGN13/14 engine, converted from diesel engine and equipped with a gas turbine supercharger. The paper presents the results of experimental studies on determining the effect of operating voltage on the dynamic characteristics of EGD. The dependences of dynamic and flow characteristics of the EGD on the change of the control signal frequency and the dependence of efficiency through the EGD flow nozzle on the control signal duration were obtained; the effect of the return spring stiffness on the dynamic and flow characteristics of the EGD were determined. The results of the work are designed to increase the efficiency of diesel trucks converted to gas.

“…A unique measuring system was designed to ensure the uniformity of the gas supply to the internal combustion engine cylinders, providing the stability of its operation, excluding detonation under dual-fuel operation, and, finally, monitoring gas consumption at the current time and for a certain period. Currently, more than 60 dual-fuel BelAZ 75131 mining dump trucks with Cummins KTA 50 diesel engines are equipped with onboard cryogenic fuel systems and successfully operated in the open-pit mines of Kuzbass (Azikhanov, Bogomolov, Dubov & Nikhrin, 2019;Dubov, Trukhmanov, Kuznetsov & Nokhrin, 2019b;.…”

The paper aims to compare the CO2, CO, CH, and O2 concentrations in the exhaust gases of Cummins KTA 50 diesel engines of BelAZ 75131 mining dump trucks equipped with an onboard cryogenic fuel system and running on diesel and gas-diesel fuel at coal mines of Kuzbass (Russia). The research novelty lies in determining ecological efficiency when using liquefied natural gas (methane) as a motor fuel for heavy-duty mining dump trucks. In the near future, the use of this type of motor fuel will minimize the anthropogenic impact on the environment by reducing harmful emissions and provoking the environmental safety of the region where a large amount of mining equipment is used in coal mining enterprises. The demand for mining dump trucks, their operating conditions, and the world experience in converting mining equipment to liquefied natural gas (methane) were briefly analyzed. The use of alternative fuel sources for heavy-duty mining trucks is a promising way to reduce harmful emissions into the atmosphere. This paper presents a research technique. The data on the study of the CO2, CO, and CH groups and O2 concentrations in the exhaust gases of Cummins KTA 50 diesel engines of BelAZ 75131 mining dump trucks hauling rock mass are presented. The obtained data on the CO2, CO, and CH groups and O2 concentrations during diesel and gas-diesel operation of empty and laden BelAZ 75131 mining dump trucks when going uphill and downhill were substantiated. The results of calculating the average weighted emissions of the CO2, CO, and CH groups in the exhaust gases of Cummins KTA 50 diesel engines were presented.
