About Us

Global Geothermal is majority owned by Wasabi Energy Ltd (ASX – WAS) and was formed in 2007 to consolidate the various worldwide entities licensed to deploy the power generation technology known as the Kalina Cycle®. As a result GGL owns and controls the Kalina Cycle® rights and the over 200 international patents associated with the proprietary technology.

Although the Kalina Cycle®’s general principals are simple and well understood, design and construction of a successful project requires an advanced process across a range of disciplines, including chemical, mechanical and mathematical.

Recurrent Engineering is the engineering and development core of GGL, providing the technical expertise to successfully leverage the Kalina Cycle® for optimized results in energy conversion system designs.

Key staff profiles

GGL's management and engineering group is a world-class team with over 150 combined years experience in the power generation industry. Our engineering core has pioneered the development, refinement and deployment of the Kalina Cycle® for over 15 years, since the technology's inception. GGL's management team consists of accomplished industry professionals with international energy project development and finance track records.
