The maritime industry is facing a critical need to transition towards sustainable practices, particularly in the tugboat sector. Tug owners are eager to invest in onboard energy storage for reducing greenhouse gas emissions, but they are hindered by the lack of dedicated shore-power charging stations at ports and harbours. The existing challenges include the higher costs associated with battery-powered tugs compared to traditional diesel-fuelled ones. However, there is optimism as the necessary battery and charging technology is available. To make the business case for low-emission newbuildings or retrofitting existing tugs financially feasible, multiple ports need to deploy charging infrastructure. Tug owners emphasize the importance of having certainty in technology, power supply, and profitability before committing to sustainable practices. The industry is shifting towards electrifying harbour vessels, with initiatives such as the installation of charging stations for battery-powered tugs in various countries like Canada, Norway, and Turkey. The call for action has been made to port authorities, governments, and terminal operators to invest in dedicated berths and charging stations to enable the construction and operation of a new generation of sustainable tugboats. The upcoming TugTechnology 2025 conference in Antwerp aims to provide technical insights and solutions for advancing the towage and tug sector towards greener practices.
