DEEP GEOTHERMAL ENERGY
Presentation to Dublin Chamber of Commerce
14th April 2011
ABOUT GT ENERGY
GT Energy is recognised as a leader in the development of deep geothermal energy projects in both Ireland and the UK.
GT Energy brings together leading technology, engineering and construction service providers in the geothermal energy sector
ACHIEVEMENTS TO DATE
• Full planning permission received
• TPA with ESB International
• Drafted geothermal legislation in Ireland
2007 2008 2009 2010 2011 GT Energy was
established to investigate and develop deep geothermal energy projects
€1.5m programme to prove the existence of a geothermal resource in Dublin commenced
Two 1.4km boreholes confirming a temperature of 46.20C indicating a temperature gradient of 32.4oC per km
Strategic Alliance signed with Ballymena Borough Council
Signed Technology Partnership Agreement with ESBI to feasibly study geothermal power generation at Newcastle site
Seismic Acquisition survey undertaken proving basin depth of 4km, est basin temp. 131 C
Pipeline of projects to include GeoHeat supply in the UK
Collaboration Agreement signed with Manchester City Council
Business model expanded to include Biomass Combined Heat and Power supply to district heating schemes
UK pipeline progression awaiting policy implementation by UK government

WHAT IS GEOTHERMAL ENERGY?• Is a natural form of renewable energy
• Is energy generated from the decay of natural materials at the earths core
• Estimated temperature of the earths core is 6,000 C
• Harnessed for centuries throughout the world
• Remains largely untapped
4,000times the earth’s energy needs could be met by
geothermal energy
HOW IS GEOTHERMAL ENERGY HARNESSED?

1. Drilling– A geothermal well doublet
system drilled to a depths of up to 5,000 metres
2. Extraction– Hot geothermal fluids are
pumped to the surface through a production well;
3. Heat Exchange– The heat is extracted
through a heat exchanger and transferred to a working fluid
– The cooled geothermal fluid from the heat exchanger is returned to the geothermal reservoir through a re-injection well
4. Distribution– Electricity, to a grid
– Heat
WHAT CAN IT BE USED FOR?• Provision of heat to district
heating schemes
• Generation of electricity
• Heat supply to large horticulture growers
• Heat supply to large Universities, Hospitals
• District cooling
• Cooling for large data centres
Geothermal Energy
THE BENEFITS
• It is not dependent on climatic conditions such as wind and solar
• It is an indigenous supply of sustainable energy that enables governments to overcome security of supply risk
• It is not subject to fuel price volatility
• Has minimum visual impact on the surrounds
• Assists governments achieve energy and emission targets
• It is a proven technology unlike many other renewable technologies
Low visual impact, ideal for urban locations
Low visual impact makes it ideal for urban locations

• Initial development framework put in place in 2001
• Industry kick started in earnest in 2009 after revision of development framework
€4bnprojects under development
currently
Pullach im Isartal
• Commenced 2004
• Two boreholes 3,500m

• Creation of 550 jobs
• Reduction of CO2
16,000t p.a
• Security of energy supply Underground energy centre
Drilling rig on site 24/7
IRELAND
• 2004 SLR funded by SEI undertook a resource assessment of Ireland
• Identified the Blackrock to Newcastle fault line
NEWCASTLE, Co. DUBLIN
• Drilling commenced 2007
– Part funded by Sustainable Energy Ireland
• Water with temperatures of 46.2°C at 1400 m
• Planning permission granted Dec 2010
• Additional funding received from SEAI to continue exploration in 2011
