Irish Ferries has taken a significant step forward in its commitment to sustainability and innovation with the transition of its Dublin Swift service on the Dublin–Holyhead route to Hydrotreated Vegetable Oil (HVO) supplied by Circle K, Ireland’s leading fuel and convenience retailer
As the first known international ferry company in the UK & Ireland to transition to HVO to power one of its ferries, this move marks a major milestone in the ferry sector, showcasing Irish Ferries’ dedication to reducing carbon emissions and enhancing environmental stewardship.
Dublin Swift travels between Dublin and Holyhead in just 135 minutes making it the fastest service across the Irish Sea. Dublin Swift recommenced its seasonal operation on 16 April, 2025, when it will transition to using HVO.
Over the season, Irish Ferries aims to ramp up usage of HVO as a diesel alternative to 100% on all four engines, which would result in up to 90% less carbon emissions compared to conventional diesel. This is part of Irish Ferries’ broader strategy to adopt cleaner energy solutions that reduces the impact of its operations on the environment and is a testament to the company’s proactive approach to integrating cutting-edge technologies and sustainable practices.
HVO is a completely fossil-free biofuel made from waste by-products and derived products not intended for human consumption from the food industry. It can be used to power diesel vehicles which means it does not release any additional carbon emissions into the atmosphere and is a cleaner and more sustainable fuel option.
By utilising HVO, Irish Ferries is not only reducing its carbon emissions but also contributing to the circular economy by repurposing waste materials.
The transition to HVO is expected to lower the Dublin Swift service’s carbon footprint, making it one of the most eco-friendly ferry services in operation.
