The transformational CaSil Technology unlocks the full energy potential of the hot water (brine) flows in a geothermal resource. It enables generation of more electricity, and the extraction of more heat for direct heating applications, without consuming additional water, i.e. more energy from the same water flow.

In current geothermal installations there is a world-wide problem of silica deposition that occurs when energy from the hot water is extracted for electricity generation and the water is cooled accordingly. The dissolved silica in the hot geothermal water polymerises and forms intractable scaling that blocks pipework, heat exchangers and reinjection wells. This severely limits the temperature to which the water can be cooled for electricity generation and heat energy extraction.

The CaSil technology solves this scaling problem at low cost. The problematic silica is transformed into a unique, proprietary nanostructured calcium silicate material (CaSil) before silica deposition can occur.

Therefore, the hot geothermal water can be cooled to much lower temperatures (e.g. to 60 degrees C or lower) than are currently attainable with existing geothermal practices; providing more electricity generation and direct heating opportunities.

The CaSil material does not adhere to metal surfaces and is separated as a proprietary product for complementary and environmentally beneficial applications.
