Yalamov, D., Georgiev, P. and Garbatov, Y. (2022), “Liquefied natural gas (LNG) as an alternative for retrofitting ageing ships”, 16th International Conference on Marine Sciences and Technologies (Black Sea 2022), October, Varna, Bulgaria, pp. 87-95.

Considering the long-term economic and energy scenarios, greenhouse gas emissions, carbon dioxide, methane, and nitrous oxide, are expected to increase concerning the emissions from around 90% in 2018 to 90-130% in 2050. Different mitigation solutions are employed, including liquefied natural gas (LNG) as an alternative fuel. The present work reviews the current state of the art of using LNG as an alternative to fossil fuels derived from crude oil (e.g., diesel) for retrofitting ageing ships. Reducing greenhouse gas emissions, especially for short sea shipping, is associated with several challenges related to employing an innovative ship propulsion system and developing a port supply infrastructure. Recently very intensive transportation activities have been observed in the region of the Black Sea, where the correlation between carbon emissions and transported cargo increased. Alternative solutions to mitigate the region’s carbonisation are analysed and discussed here.
