A Little Background – W2W

• Waste to Wealth Research Programme

• Identify the next logical steps for minerals in

geothermal brines

• Is it worth taking these steps ?

• Ultimately the question is :

– Are the minerals in the geothermal brines a potential

resource

• If yes then what are the actions that might better

facilitate utilisation

GNS Science

The three questions

1. Most exciting / promising aspect from the work

so far

2. Barriers to be overcome and/or key factors

that will drive success in developing a

geothermal minerals industry in NZ

3. Questions / knowledge / gaps for future

research / investment

Paradigms

GNS Science

Beyond the Square

12

GNS Science

For Geothermal Energy Production

• Energy companies keen to keep minerals in

solution in the brines

13

• Taking it out is beyond the square

GNS Science

Beyond the square - Here is another one

• The methods discussed today are physical

and chemical methods

14

GNS Science

Biological Methods

• Biological methods have not been researched

• Geothermal community know that microbes are

superbly effective

– Industry spend many $$$

on cooling water biological control

– Wairakei - the cooling water bioreactor

• 13 cumecs in four minutes

15

GNS Science

Beyond the square

• Pick these up on your stickies
