• The Geothermal Association of Ireland (GAI) was formed as a not for profit association in 1998 to promote the development of geothermal energy in all its forms in Ireland.

• GAI is committed to education and awareness building to promote the use of geothermal as a sustainable energy system in Ireland.

• Membership of close to 100• http://www.geothermalassociation.ie/

Geothermal Energy Ireland – Study for SEAIUndertaken by CSA (Roisin Goodman & Gareth Jones)

Mapping of current geothermal energy resources in Ireland

Identify & analyse sources of geothermal energy utilisation.

GIS-linked geothermal database – series of maps publically available

‘Play Fairway Analysis’ an assessment of geological resource exploration risk on a geological basin scale used by the oil exploration industry. The study is the first attempt to apply this technique to the analysis of the geothermal potential of Ireland.

IRETHERM is a significant new geothermal energy research project funded by a Science Foundation Ireland (Grant No. 10/IN.1/I3022) to Principal Investigator Alan Jones (DIAS). • Academic-government-industry collaborative project

(currently 9 institutions/companies and 14 scientific collaborators formally involved).

• North-South “all-island” Ireland initiative.

• Initiated: April 2011

• Duration: 54 months

• Website: www.iretherm.ie

Case Study: Undergraduate Project Investigation of (some of the) parameters controlling

thermal conductivity in concrete mixes

Important so that the thermal parameters of ‘energy foundations’ can be optimised

Note: Energy Foundations are a type of closed loop ground source energy system whereby piping is installed into structural piles in order to reduce drilling costs

Parameters investigated include: water-cement ratio, sand-cement ratio, aggregate type & aggregate propertiesUCD Research Energy

Salmonoidal river– Environmental Protection Agency approved monitoring system– Reduced CO2 emissions by 740 tonnes p.a.– Capex €2.5m

• IKEA Ballymun Dublin– Dublin store construction figures:– 1.5 MW capacity for both heating & cooling – geothermal systems 150 bores 120m deep– A total of 18,000 metres of drilling– Borehole drilling cost per metre: €65-€70– Each 12m of drilling equivalent to 1kw of heating & cooling capacity– €2 million cost – over 50% was cost of borehole field

Summing-Up• Regulatory drivers & energy cost will continue to push the need to adopt

renewable technologies. Geothermal applications offer a clean, effective solution.

• Improving wind energy contribution to Irish grid will lower CO2 emission factor and grid Primary Energy Factor. This will greatly enhance the importance of GSHPs in reducing CO2 emissions.

• GSHPs offer life-cycle cost competitive alternative to oil and LPG boilers• Promotion of proven, high quality, lower life-cycle cost installations

essential. ‘Installation of the Year’ competition plays an important role.• GAI Conference in November 2013. Location – Kilkenny. See you there!
