Questions on Vulcan from a beginner, page-18

-Anyone know why they listed in Oz and not Europe? -

disallowed in Australia is kind of specialised for Mining startups, there are some venture capital Investors who are into Mining. And one of the founders (Mr Wedin is from Australia).

-Geothermal power generation is trickier than it seems. Contamination of the water/steam is a major problem leading to corrosion of the Turbine? -

The Turbine is not in contact with the brine. They Transfer the heat to another Fluid with a Differential boiling points. Searchwords are Organic Rankine Cycle, the manufactorer is likely the company Turboden in Italy, a subsiary of Mitsubishi. They are mentioned in the DFS and they built the Turbine in the Insheim Geoth. plant that Vulcan already owns. Scaling is still a issue. Valentin Goldberg (KIT Researcher) has some Interviews out on that topic. It sooms to me that the newest publications of vulcan energy are more conservative due to Flow rate and Scaling, they may have Adresse this.

-A geothermal unit is low temperature (160°C in this case) and therefore low pressure requiring much higher flowsof steam to operate. -

They Do not use geothermal steam at all. The goal is to Transfer the heat to another working Fluid and keep the geothermal brine liquid (and therefore pressurized) all the time to avoid Scaling. I Do not know good this goal is achived.
