The Geothermal Association Of Ireland


The Geothermal Association of Ireland (GAI) was formed in 1998 as a centre for all involved in geothermal energy in Ireland. GAI is a not-for-profit organisation whose aim is to promote the use of sustainable geothermal energy.

Our members are involved in all aspects of geothermal.

GAI is affiliated with the European Geothermal Energy Council (EGEC) and the International Geothermal Association (IGA).

Our Mission

GAI's mission is to promote the sustainable development of geothermal energy in Ireland.

We aim to:

  • Improve the understanding of clean geothermal energy.
  • Support our membership and our communities to deliver geothermal energy to the highest standards.
  • Represent our membership: we are the voice for the Irish geothermal industry domestically and internationally.

Geothermal Energy

  • Geothermal is a low-carbon, viable, sustainable source of energy.
  • Globally geothermal energy produces over 90 TWhr, or enough energy to power Ireland three times over.
  • Geothermal is used for heating, cooling and electricity.
  • By 2040 Munich plans to heat over half a million homes using district heating powered by geothermal. That's the equivalent supplying all of Dublin's houses with heat from geothermal.


Our members cover all aspects of the geothermal industry in Ireland and Northern Ireland, and we represent our membership's interests. 

We organise and support webinars/seminars and workshops on all aspects of geothermal, both public and for our membership.

GAI and its members support and design the industry standards and guidelines for geothermal. 

Our members get access to Geotrainet.

GAI's Vice Chair represents the interests of Ireland's geothermal industry at EGEC which promotes the European geothermal industry in Europe and worldwide, by shaping policy, improving business condition, and driving more research and development.

GAI is a member of Renewable Energy Ireland.
