Due to environmental, energy, and operating cost constraints, the number of liquefied natural gas (LNG)–powered ships is increasing. To avoid decreasing the thermal efficiency of two-stroke, low-speed diesel engines, high-pressure gas injection is used. The specific energy consumption of a gas fuel compressor is around 0.35 kWh/kg, which has a negative impact on the efficiency of ship power plants...
The paper presents technologies currently being developed for methanol production and its applications. Particular attention was paid to energy storage technology in the form of “renewable” methanol, which is produced from hydrogen generated from surplus energy from renewable energy sources and from captured CO2. The global methanol market was characterized, i.e. global demand, major producers and...
Currently, about 90% of world transport is via water, which means that maritime transport is a decisive factor in the development of civilization. In order for it to effectively continue and compete with other means of transport, it is necessary to use the cheapest marine fuels on ships. The demand for machines generating mechanical energy to propel ships resulted in their dynamic development and,...
