Geothermal District Heating and Cooling Days 2026
The Geothermal District Heating and Cooling Days 2026 was held in Dublin from the 3-4 September, 2026. It was organised by the European Geothermal Energy Council (EGEC), in collaboration with the Geothermal Association of Ireland (GAI).
Purpose of activity
The Geothermal District Heating and Cooling Days 2026 brought together European and Irish experts, policymakers, project developers, investors and other stakeholders to explore how geothermal energy can play a greater role in decarbonising heating and cooling.
Held in Dublin on 3–4 September, the event aimed to move the conversation around geothermal from potential to practical deployment. The conference focused on “Unlocking Geothermal Heating and Cooling Markets”, sharing experience, innovative approaches and lessons from projects across Europe, while examining the policy, investment, business and technical conditions needed to accelerate the uptake of geothermal heating, cooling and thermal storage.
A particular focus was placed on Ireland’s emerging geothermal market, including the development of an investable project pipeline and the ecosystem needed to support delivery. The accompanying workshop explored finance, risk and delivery, with participants working collaboratively to identify pathways for growing geothermal in Ireland.
For GEMINI, the event provided an important opportunity to share learning from its demonstration work, connect Ireland’s emerging geothermal sector with European experience, and contribute to the wider discussion on how geothermal solutions can be replicated at scale.
Codema's role
As lead partner of the GEMINI project, Codema played an active role in bringing the project’s experience and expertise to the Geothermal District Heating and Cooling Days 2026.
GEMINI was a sponsor and collaborating partner for the event, which was organised by the European Geothermal Energy Council (EGEC) and the Geothermal Association of Ireland (GAI). Codema helped connect the event’s European perspective with the practical experience emerging from GEMINI’s work to demonstrate geothermal solutions across the island of Ireland.
Through our involvement, Codema contributed to knowledge exchange and discussion around the opportunities and challenges of developing Ireland’s geothermal sector. This included sharing insights from GEMINI’s four demonstration sites and its wider work to build the knowledge, skills, policy and market conditions needed to accelerate geothermal deployment.
The event also provided an opportunity for Codema to connect with European geothermal experts, policymakers, industry and other stakeholders, strengthening networks and helping to bring international experience back into GEMINI’s work.
Overall, our role was to help ensure that the event supported collaboration, learning and momentum for geothermal heating and cooling in Ireland, while positioning GEMINI within the wider European geothermal community.
Key outcomes
The activity provided valuable insights into the potential for geothermal energy to play a much greater role in Ireland’s heating and cooling transition. Excellent case studies and examples from countries including the Netherlands and Finland demonstrated how geothermal energy is already being successfully integrated into heating and cooling systems, providing practical evidence of what could be achieved in Ireland.
The conference also highlighted the importance of creating the right financial, policy and market conditions to unlock geothermal development. Discussions around public funding, including EU funding opportunities, and private investment provided useful insights into potential routes for financing geothermal projects. It also reinforced the important role of government policy in creating a supportive regulatory environment, providing certainty for investors and helping to reduce the risks associated with developing new geothermal projects.
For Codema and GEMINI, the event offered an important opportunity to learn from international experience, share knowledge and strengthen connections with European geothermal stakeholders. A key takeaway was that Ireland can learn from countries where geothermal heating and cooling is already established, while developing the right policy, funding and market frameworks to support the sector’s growth and build an investable project pipeline.
