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, simultaneously, forced the search for primary energy sources (fuels) that enable the production of the working medium. The era of coal and petroleum fuels began in the 19th and 20th centuries, respectively. Today, in the 21st century, we stand at a crossroads – what next? The transition fuel will likely be LNG and biofuels. Ammonia will also occupy a significant share of the fuel market, but the target fuel will be hydrogen. Based on historical and contemporary sources, this article discusses the changes in the use of marine fuels that have occurred since the 19th century.
