“…This might be partly explained by the widening of the biogas flammability limits caused by the added hydrogen. The favorable results of previous studies has encouraged the research of biogas-hydrogen blends in other combustion systems, such as combustion engines or power-to-methane cycles [30,31]. The results agree with former research works, proving the increase in detonation characteristics of biogas by adding hydrogen percentages between 0 and 20% [32].…”

Biogas is a renewable gas with low heat energy, which makes it extremely difficult to use as fuel in conventional natural gas equipment. Nonetheless, the use of hydrogen as a biogas additive has proven to have a beneficial effect on flame stability and combustion behavior. This study evaluates the biogas–hydrogen combustion in a conventional natural gas burner able to work up to 100 kW. Tests were performed for three different compositions of biogas: BG70 (30% CO2), BG60 (40% CO2), and BG50 (50% CO2). To achieve better flame stability, each biogas was enriched with hydrogen from 5% to 25%. The difficulty of burning biogas in conventional systems was proven, as the burner does not ignite when the biogas composition contains more than 40% of CO2. The best improvements were obtained at 5% hydrogen composition since the exhaust gas temperature and, thus, the enthalpy, rises by 80% for BG70 and 65% for BG60. The stability map reveals that pure biogas combustion is unstable in BG70 and BG60; when the CO2 content is 50%, ignition is inhibited. The properties change slightly when the hydrogen concentrations are more than 20% in the fuel gas and do not necessarily improve.

“…It is worth noting individually the electric energy, that is the most ecologically friendly type of fuel. Most widely spread sources of energy for transport vehicles are lithium-ion cells, fuel and hydrogen elements, solar cells and supercapacitors [4,5,6]. Classification of the motor vehicles, using electrical and hybrid drives is shown in the paper [7].…”

Development of the automobile industry leads to annual increase of the quantity of the automobiles. In 2020 more than 78 mil. motor vehicles were manufactured in the world, lion share of the quantity falls on such manufactures as Toyota Motor Corporation (9.5 mil) and Volkswagen Group (8.7 mil). It is obvious that such amount of the world auto pool will cause numerous problems, first of all, it is the pollution of the environment by the exhaust gases and traffic jams. In particular, over 20% of all carbon dioxide (СО 2 ) emissions is generated by motor vehicles.The paper contains the list of the basic alternative sources of fuel, used in transport vehicles, such as ethanol, butanol, liquefied natural gas (LNG) and compressed natural gas (CNG), hydrogen, biogas, also the sources of electric energy for transport vehicles are: power lithium-ion batteries, fuel and hydrogen cells, solar cells and supercapacitors.Technique for determination of the fuel and equivalent efficiency, used in the USA and problems dealing with its implementation in Ukraine is considered. It was established that the Ukrainian legislation does not contain statutory-instruments, regulating the technique for determination of fuel efficiency of the transport vehicles, including the vehicles which use the alternative sources of energy. Equivalent fuel efficiency of the following motor vehicles was studied and analyzed: Chevrolet Lacetti (petrol), Renault Logan (diesel), Honda FCX Clarity (hydrogen), Ford C-Max (alcohol-containing fuel), Renault Sandero (biodiesel fuel), Nissan Qashqai (biogas), Citroёn C4 (liquefied natural gas), Nissan Leaf (electric energy). Results are presented in the form of graphic dependences.

“…Окремо варто зазначити електроенергію, використання якої на автотранспорті є найбільш екологічним. Найпоширенішими джерелами електроенергії для транспортних засобів стали силові літій-іонні акумулятори, паливні та водневі елементи, сонячні батареї та суперконденсатори [4,5,6]. Класифікація автомобільних транспортних засобів, які використовують електричні та гібридні приводи наведено у роботі [7].…”
