Wightlink FastCat

This project is a feasibility study focused on decarbonising the Wightlink FastCat ferry route between Portsmouth and Ryde by identifying and modelling zero-emission energy solutions especially in port while the vessel is docked. The
FastCat vessels currently rely on diesel engines not only for propulsion but also for auxiliary power when stationary in port, contributing to greenhouse gas emissions, poor air quality, and noise in both terminals.
The study will model the energy requirements of the vessels while in port, assess the viability of renewable shore-side energy systems, and evaluate the latest state of the art renewable technologies available. It will also assess the readiness of port infrastructure at both locations, examine regulatory and safety considerations in consultation with the Maritime and Coastguard Agency, and provide a detailed roadmap to implementation, including technology options, CAPEX/OPEX modelling, emissions impact, and timelines.
This is a pre-demonstrator feasibility phase and will not involve any Innovate UK-funded on-water activity, making it fully compliant with programme scope. All work will be carried out through analysis, stakeholder engagement, and modelling. What makes this project innovative is its focused approach of integrating renewable power into a real-world, high-speed passenger ferry service with unique operational constraints---short crossings, tight turnaround times, and energy-intensive performance. While other maritime decarbonisation projects exist, few target high-speed, passenger-only vessels or offer a combined analysis of both shore-side and onboard energy transition. The project also emphasises full lifecycle GHG emissions and air quality improvements, looking beyond tailpipe reductions to a systems-level decarbonisation strategy. The modelling of renewable technologies for vessel power while docked will be modelled as part of the overall in port decarbonisation while the vessel is docked at Gunwharf Quays and Ryde Pier. It is one of the first UK studies to fully explore how renewable energy infrastructure can replace in-port diesel use for fast ferries in preparation for a future zero-emission demonstrator vessel. The findings are expected to be of interest and value to other short-sea routes and ferry operators across the UK. The project will provide Wightlink and the wider sector with a robust, regulator-informed pathway toward operational zero-emission high-speed ferry services,unlocking clean air, fuel savings, and long-term emissions reductions.
