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

Cliffs of Moher

Heating & Cooling Invisible – no flues! No emissions No boreholes Minimum plant Poor soil/water 6km Collector 120kW

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

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!
