The EU Commission's alternative fuels strategy aims to reduce the transport sector’s reliance on fossil fuels, with Directive 2014/94/EU mandating shore-side electricity (SSE) and LNG refueling infrastructure in TEN-T Core Network ports by 2025, unless demand or cost barriers exist. This report examines the feasibility of SSE for seagoing ships and the market demand for LNG refueling in Irish ports by analyzing successful Alternative Fuel Infrastructure (AFI) deployments in major ports like Rotterdam, Oslo, and Vancouver. Findings indicate that successful AFI implementation depends on economic factors such as low energy costs, geographic advantages, and strong regulatory support, highlighting the need for strategic policy and investment in Ireland.
