Dublin Airport's Geothermal Journey
This is the third webinar in our 2026 Geothermal Webinar Series.
Webinar Speaker:
Jeremy Carkner, Senior Project Manager (Sustainability) - daa
This webinar outlines the airport’s geothermal study and how ground‑source heating and cooling could cut its Scope 1 emissions.
Dublin Airport recently completed one of Ireland’s largest geothermal feasibility studies, exploring how ground‑source heating and cooling could help the airport cut its Scope 1 emissions by 51% by 2030. Focusing on the energy‑intensive areas around Terminal 2 and key piers, the study assessed the potential for a district‑scale geothermal heat pump system of up to 10 MWth, combining open‑ and closed‑loop technologies across multiple test sites.
This webinar will walk through the airport’s geothermal journey—from subsurface investigations and thermal response testing to detailed system modelling—and highlight the practical challenges of integrating geothermal solutions within a busy operational airport. Attendees will gain insight into how geothermal can play a central role in low‑carbon infrastructure, master planning, and campus‑wide energy optimisation.
As one of the country’s most ambitious geothermal initiatives, the project offers valuable lessons for infrastructure owners, designers, and policymakers seeking to scale renewable heating and cooling across airports, data centres, and industrial campuses.
