Since 16 April 2025, the DUBLIN SWIFT—the fastest ferry across the Irish Sea—has operated on Hydrotreated Vegetable Oil (HVO), a fossil-free fuel from waste by-products. This move makes Irish Ferries the first international ferry company in the UK & Ireland to power one of its vessels with HVO.
Supplied by Circle K and their certified low-emission diesel alternative, milesBIO HVO100, the transition could reduce carbon emissions by up to 90% compared to conventional diesel as the season progresses towards 100% HVO usage across all four engines.
