It is one of the most efficient means of transportation, wherein over 11 billion tons of goods are transported annually, accounting for nearly 90% of global trade, as estimated by the United Nations Conference on Trade and Development (UNCTAD). However, the industry is primarily based on fossil fuels, of which nearly half (as of 2021) is powered by heavy fuel oil (HFO), a sludge-like residue left over from petroleum cracking. The International Maritime Organization (IMO) forecasts that CO2 emission from commercial shipping could increase by 50-250% before 2050.<\/p>\n<p>Emphasized by the urgency to reduce carbon footprint, the challenge is not technologically trivial as electrification of the entire sector. For instance, one of the most successful battery electric technology demonstration till date is Yara Birkeland, a 120 TEU (Twenty-foot Equivalent Units) capacity vessel, which covered a range of 65 nautical mile. Disregarding complexities in raw materials and sourcing electric power, a mix of solutions are necessary, and the topic of energy transition is one of the most pressing issues of our time.<\/p>\n<p>The drive for decarbonization in the shipping sector, at present,\u00a0mainly follows legislation, with IMO introducing radical changes. This began with cleaning up\u00a0of\u00a0the combustion process from usage of HFO via implementation of the Global Sulphur Cap (2020). Furthermore, the Energy Efficiency Design Index (EEDI) and more recently Carbon Intensity Index (CII), aim to holistically account for and reduce energy consumption on board. Compliance with these regulations presents many options for merchant vessel operators such as engine upgrades, exhaust aftertreatment systems, hull and propeller overhaul or use of clean fuels. Worth noting that each percentage point improvement in efficiency translates to roughly \u00a0\u20ac40,000 annual saving in operational costs.<\/p>\n<p>Being located in close proximity to the energy cluster of Finland, our research at the university deals with this issue, especially focused on the propulsion systems. Our state-of-the-art laboratory facilities and close collaboration with industry enable us to lead large projects such as:<\/p>\n<p><a href=\"https:\/\/cleanpropulsion.org\/\">Clean Propulsion Technologies<\/a><\/p>\n<p><a href=\"https:\/\/www.projectchek.eu\/\">Decarbonizing Shipping by Enabling Key Technology Symbiosis on real vessel concept designs<\/a><\/p>\n<p><a href=\"https:\/\/sites.uwasa.fi\/silentengine\/\">Silent Engine<\/a><\/p>\n<p><a href=\"https:\/\/www.uwasa.fi\/fi\/tutkimus\/hankkeet\/casemate-computationally-aided-systems-engineering-marine-advanced-technology\">Computationally Aided Systems Engineering for Marine Advanced Technology for the Environment<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>About the author:<\/p>\n<p>&nbsp;<\/p>\n<div class=\"wp-block-image is-style-rounded\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6522\" src=\"https:\/\/moan-stall-sway.dev02.wphost.fi\/wp-content\/uploads\/2023\/05\/thumbnail-profile-pic-edited.jpg\" alt=\"\" width=\"201\" height=\"201\" \/><\/figure>\n<\/div>\n<p>&nbsp;<\/p>\n<p>Aneesh Vasudev is a PhD scholar in energy technology at University of Vaasa.
