The AGGAT Global Conference 2015 - An overwhelming success!



The first ever Global Conference on Above Ground Geothermal and Allied Technologies (AGGAT) was held on 30th April 2015 in Auckland. Around 60 delegates attended this conference covering a mix of industry, academia, field experts and government.

The conference was divided into the following research themes which also form the basis of the AGGAT Research Roadmap:

  • Technology Concepts: Processes or technology concepts to deliver energy outputs in smarter, faster or more cost-effective ways
  • Control Systems: Control strategies moving beyond business as usual
  • Heat Transfer and Design: Heat exchanger systems and data analysis to optimise power generation systems
  • Turbine Design and Performance: Turbine designs and selection for processes and performance in different operating situations
  • Materials and Fluids: The right materials and fluids for the right operating conditions

A networking evening was held at the conclusion of the conference where delegates had the opportunity to continue their discussions in a more relaxed setting over drinks and nibbles. 


Copies of the presentations are available upon request. Please find our contact details at the end of this page.
