Dublin-Holyhead ferry route identified as a leading candidate for green shipping corridor

The announcement that the Dublin–Holyhead ferry route could become one of Europe’s first dedicated green shipping corridors marks a defining step for both maritime and land-based transport. As the busiest roll-on/roll-off link between Ireland and the UK, carrying 70% of all passenger movements and nearly 80% of Ireland’s unitised freight, this corridor is more than just a sea crossing, it is a critical artery in Europe’s logistics network.

The study, led by Ricardo with ferry operators, ports, universities, and EDF, identified green methanol as a viable alternative fuel, capable of reducing greenhouse gas emissions by up to 80%. Importantly, methanol allows for vessel retrofits and can be handled using established bunkering practices, creating a realistic near-term pathway compared with hydrogen, ammonia, or battery-electric options for vessels of this scale.

Why This Matters for Fleets

At ZeroMission, we see the Dublin–Holyhead green corridor not simply as a shipping project but as a direct enabler for fleets across Ireland, the UK, and mainland Europe. Here’s why:

Decarbonisation Across Modes
Fleets are under increasing pressure to decarbonise. A cleaner maritime leg of the journey reduces the embedded emissions of goods transported, directly supporting fleet customers in meeting Scope 3 reporting obligations and ESG targets.
Cost and Operational Certainty
By standardising on methanol, the corridor provides fleets with greater supply chain predictability. Operators can plan with confidence, knowing that their goods move through a corridor aligned with EU and UK climate goals – de-risking compliance costs in the years ahead.
Integrated Digital Twins for Transport
At ZeroMission, we are building digital twins of mixed-fuel fleets and supply chains. The inclusion of maritime legs in decarbonisation strategies means our analytics can now integrate cleaner sea freight data with land fleet operations, giving companies a 360° view of emissions, costs, and performance.
Policy Alignment and Funding Opportunities
The corridor strengthens the case for government-backed incentives. For fleets, this could unlock access to grants, carbon credits, or preferential contracts for shippers using low-emission supply chains. ZeroMission is already helping customers identify and apply for such opportunities.
Market Signal for Innovation
This initiative sends a strong signal to technology providers, investors, and logistics companies: the Irish Sea is becoming a testbed for green corridors. Fleets that move early to align with this shift will secure both competitive advantage and reputational leadership.

Looking Ahead

Like fleets, ports and ferry operators face the challenge of choosing the right fuel pathways amid a crowded field of options. Focusing on green methanol as a practical, near-term solution offers the clarity required to invest, trial, and scale.

For ZeroMission, this is a pivotal example of joined-up decarbonisation: aligning fleets, ports, vessels, and energy providers in a single ecosystem. As the corridor develops, we will continue working with our customers to ensure their fleets can leverage these cleaner supply chains, from depot to dockside and beyond.

The Dublin–Holyhead corridor has always been an economic lifeline. Now, it has the potential to become a green lifeline, proving that decarbonisation is not just about technology, it’s about rethinking how every link in the supply chain connects.
