NZGW 2022 conference paper examining current business venture arrangements of large geothermal operations (electricity and process heat) in New Zealand.

This NZGW 2022 conference paper provides an update on the main objectives, relevance, future linkages, and the initial results three years into this challenging and strategic scientific endeavour.

Flow-through experiments were conducted in the temperature range of 200–400°C, and in presence of a New Zealand greywacke rock substrate to evaluate the thermal behaviour of rhenium and indium.
