Kia ora and welcome

Above Ground Geothermal and Allied Technologies (AGGAT) is an overarching definition for a programme which encompasses all aspects of above ground technologies that are based on geothermal and/or other allied heat sources. The programme uniquely brings together researchers, industry and international partners for the first time in a collaborative setting drawing on each others expertise in research, fabrication, knowledge and experience to deliver new AGGAT products using an established platform of research and development and a functioning innovation pipeline.

AGGAT affiliation

AGGAT is a project of the New Zealand Heavy Engineering Research Association (HERA). It is run in cooperation with partners from industry and academia on behalf of the New Zealand industry.
