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

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?

4

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

GEOTHERMAL ENERGY DEVELOPMENT GERMANY

• 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
