Industrial & Commercial Enterprises need to reduce energy cost
• Vistakon – Limerick
– Using an open loop system to provide 1MW of direct cooling
– 2 pumps, 35m lift, variable flow
– Aquifer temperature 11°C, discharge temperature <19°C to
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

GSHP - Domestic Small
Scale Exploitation
• Single Dwelling Heat Pumps
• 10-30 kW
• Started to be accepted
• Strong growth
• Market collapse
Need to avoid emerging technology issues:
- Equipment standards
- System design
- Technician standards
- Government subsidy programmes

REGEOCITIES_ CONCEPT
SPECIFIC OBJECTIVES
1. Overcome barriers to regulation of geothermal resources & administrative
procedures.
2. Identification and transferring of best practices from mature to juvenile regions
3. Make Recommendations to develop a common pre-normative framework
4. Engagement of local administration for implementing project results
5. Development of a training program focused on the target groups (administrative
personnel from the cities and regions)
6. Achievement of the smart-cities concept within shallow geothermal systems
Final Goal - the implementation and adoption of the project recommendations by means of
the endorsed cities and regions in order to promote the GSHP and help to achieve the
objectives marked in the NREAP documents

Deep Geothermal – Dublin Basin
• First geothermal exploration project at the Blackrock to
Newcastle Fault (BNF) identified as a potential
geothermal target;
• Commenced in 2007 and included the drilling of two
deep exploratory boreholes to a depth of 1,400m in 2008;
• Water bearing fractures with temperatures of 46.2°C

GEOTHERMAL ASSOCIATION OF IRELAND
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. Continued improvement in Ireland’s electricity generation and
distribution systems will reduce the Primary Energy Factor. These 2
factors will greatly enhance the importance of Ground Source Heat
Pumps in reducing CO2 emissions.
• GSHPs offer life-cycle cost competitive alternative to oil and LPG boilers
• Research into Ireland’s geothermal energy potential and public support
for district heating schemes will open up new opportunities for deep and
shallow geothermal energy.
• Promotion of proven, high quality, lower life-cycle cost installations is
essential. ‘Installation of the Year’ competition plays an important role.
• GAI Conference in November 2013. Location – Kilkenny. See you there!
