In a statement today, the Queensland-based company said it had signed a memorandum of understanding with Exorka ehf – an affiliate of Iceland’s Geysir Green Energy – regarding a potential merger.
On its web site, Geodynamics said it owns the exclusive rights in Australia and New Zealand for the Kalina cycle technology, which it describes as a more efficient way of converting mid-to-low temperature heat sources into electricity.
“GPS [a 100%-owned subsidiary of Geodynamics] is working to commercialise Kalina with prospective customers, both in waste heat and geothermal applications,” it said.
“In simple terms, Kalina cycle is a Rankine cycle that uses an ammonia-water mixture as its working fluid in instead of organic hydrocarbons used in conventional organic Rankine applications.”
The first commercial Kalina cycle power plant was installed in Japan in 1998 to utilise waste heat. It produces 3.1MW of power.
The following year, a second plant was installed in Iceland, which produces 1.8MW of power from a conventional geothermal reservoir.
