TL;DR: The challenges and changes that have occurred over the last 50 years of remarkable service from the Wairakei Geothermal Power Project are reviewed in this article, where the authors describe various aspects of the project development that have contributed to its success.

TL;DR: In this article, preliminary experiments using two chemicals (CaO, a quicklime, and a cationic nitrogen-bearing precipitant, EC-004) to remove silica from geothermal brine were undertaken at the Mokai geothermal plant, New Zealand.

TL;DR: In this article, precipitated amorphous silica is discussed in terms of its strategic and beneficial value to expanded energy generation in geothermal development, removal of environmentally sensitive constituents and as a marketable commodity in its own right.

TL;DR: Taupo township is located in the south western apex of the Taupo Volcanic Zone (TVZ), in the centre North Island of New Zealand, which has an abundance of high temperature geothermal resources.

TL;DR: In this paper, the principles of the new legislation, as it relates to the management of geothermal resources, and the regulatory framework within which control will be achieved, are outlined, and strategies for the sustainable management of New Zealand's main high temperature geothermal resource system.
