This map was created to help identify the best locations of geothermal energy available in Ireland.
In 2004, CSA Group completed an SEAI commissioned study, which aimed at identifying the potential resources of geothermal energy in Ireland. One of the outcomes of the project was to create a series of geothermal maps for Ireland.
This map has taken the results of that study, displayed them and applied them to renewable technologies. The maps will be particularly useful for people interested in assessing the geothermal potential at any location in Ireland. This includes researchers, consultants and decision-makers.
What you will find in this map
Geothermal Modelled Temperatures (degrees Celsius)
This layer displays the modelled subsurface temperatures at 10m, 100m, 500m, 1,000m, 2,500m and 5,000m depths. It is displayed in bands of varying degrees. The exact modelled temperature can be seen for a particular area by clicking on that area on the map.
GSI Vertical Closed Loop Suitability
Closed loop collectors are systems where heat is extracted from the ground, or cooling is gained. This happens by pumping a heat exchange fluid through closed pipes within the ground. The pipes can be installed in borehole(s) (vertical closed loop) or laid out horizontally (horizontal closed loop). This layer shows the suitability of this technology in any given area in the country.
GSI Open Loop Domestic Suitability
Open loop ground source heat systems operate by taking heat energy from abstracted groundwater using a heat pump. The volume of groundwater that can be abstracted from a borehole is known as the ‘yield’. This also applies to the volume taken from a spring each day. The yield determines the total amount of heat energy available. This determines the size of heat pump that can be used and the size of building that can be heated. This layer shows the suitability of this technology for domestic purposes in any given area in the country.
GSI Open Loop Commercial Suitability
This layer shows the suitability of the same technology listed above but for commercial purposes. Commercial entities would require a larger “yield” and systems in order to benefit from this technology. Therefore the suitability in any given area can be different to those looking to use it domestically.Visit the Geothermal Map
