| Abstract | Dublin Airport is undertaking a large-scale geothermal feasibility study to explore the integration of ground source heating and cooling technologies into its energy intensive infrastructure. With a target to reduce Scope 1 carbon emissions by 51% by 2030, the project focuses on Zones 1 and 3 of the campus, which include Terminal 2 and several high demand piers. The initiative explores the potential deployment of a district-scale geothermal heat pump system of up to 10 MWth capacity, using a mix of open- and closed-loop systems across five test locations. This paper presents the methodology, scope, and expected impacts of the feasibility study, which includes subsurface characterisation, thermal response and pumping tests, and detailed system modelling. The study also addresses integration challenges within operational airport environments, such as maintaining service continuity and interfacing with existing BMS and HVAC systems. The work reflects growing momentum in applying geothermal to critical infrastructure and urban development. Dublin Airport is positioned as a strategic demonstration site where geothermal becomes a central pivot in an emerging low-carbon energy ecosystem supporting heating, cooling, and broader energy optimisation across the campus. By embedding geothermal early into master planning and coordinating across airport operations, engineering, and planning teams, this project offers valuable lessons for infrastructure owners, designers, and policymakers. As one of Ireland’s most ambitious geothermal efforts to date, the study aims to set a new standard for renewable integration in the built environment and inform broader replication across airports, data centres, and industrial campuses. |
