[LINK] Enhanced geothermal electricity

[stephen at melbpc.org.au]

A pleasing announcement. At its best, geothermal power generation uses no
coal, oil, earth-movement etc to generate electricity. An EGS is a closed 
system producing electricity with no input required. They simply drill two 
holes into bedrock, then create/extend a fracture-cavity 'ball' in the hot 
rocks. They pump water down one hole and up it comes out the other one hot 
enough to generate electricity. Optimally, it's a completely closed system.

Of interest, Geodynamics received half of their start-up capital from ANU.
They're already the star of the Wikipedia EGS world chart. Now they shine.

ASX Announcement

GEODYNAMICS LIMITED

2 May 2013: Habanero 1 MWe Pilot Plant Successfully Commissioned

Geodynamics Limited (ASX:GDY) is pleased to advise that our 1MWe Habanero
Pilot Plant has been successfully commissioned and has produced Australia’s
first Enhanced Geothermal Systems (EGS) generated power. 

The company has now commenced the planned demonstration trial and testing
program which is scheduled to run for approximately 100 days with
completion in August 2013. 

Managing Director and CEO Mr Geoff Ward said "The generation of power at
our 1MWe Pilot Plant is a major milestone for geothermal power in Australia
and EGS technology globally." 

"The commencement of the demonstration trial is the culmination of many
years of hard work and the application of rigorous engineering and field
operations. I congratulate all the team involved in delivering this
milestone. The Habanero EGS Project is a globally significant demonstration
of EGS geothermal capability. I would like to acknowledge the support of
the Australian Government through the Australian Renewable Energy Agency’s
provision of the Renewable Energy Demonstration Program grant funding. This
has been critical to allowing Geodynamics to achieve this milestone and
demonstrate world leading capability in this area of geothermal technology.
We look forward to successfully completing the planned testing program."

About Geodynamics 

Geodynamics is the leading Australian geothermal exploration and
development company. Geodynamics possesses some of the best geothermal
resources in the world and is rapidly developing technology to exploit the
resource. Geothermal energy has the potential to be a critical element of
Australia’s future power generation and Geodynamics is at the forefront of
development. 

About geothermal energy 

Geothermal energy offers the prospect of zero carbon, base-load energy
generation. "Zero carbon" means that no carbon dioxide (CO2) will be
emitted when generating energy. This is different from some other 
forms of ‘renewable’ energy, which still result in significant CO2
emissions. ”Base-load” means that power is available 24 hours a day, 7 days
a week, all year round, and therefore can be used to meet energy needs at 
any time. This is a significant advantage compared to a number of other
zero-carbon technologies that are more intermittent (such as wind, wave and
solar power). 

Geothermal energy produced from hot fractured rocks, also known as
Engineered or Enhanced Geothermal Systems (EGS), is generated by special
high heat producing granites located 3km or more below the Earth's 
surface. The heat inside these granites is trapped by overlying rocks which
act as an insulating blanket. The heat is extracted from these granites by
pumping water through fractures in the granite and bringing the hot 
water to surface. Geodynamics believes that energy produced using EGS
technology is capable of generating base-load power at a cost that will be
very competitive with other energy sources (both low carbon and otherwise).
