Quantum Graphite's (ASX: QGL) joint venture partner Sunlands Energy Co. has been granted an Australian patent by the Commissioner of Patents for its thermal battery technology.
This patent, and the recent grants in the USA and South Africa underpin the joint venture's access to one of the largest and fastest growing segments of the global energy markets.
Installations of energy storage systems globally including LDES increased by almost 300% in 2023 and forecast to grow by more than 20% annually in the next five years. The joint venture’s participation in this global market has the potential to deliver the Company the single largest demand source for its coarse flake products.
Patents now granted in USA, South Africa and Australia
Sunlands’ Graphite Cell technology was the subject of an international patent application in November 2017. The application was made under the World Intellectual Property Organisation’s Patent Cooperation Treaty which covers 155 countries.
The grant of the Australian patent follows the USA and South African patent grants for the same system. Sunlands Energy Co. is now waiting only on the European (including the United Kingdom) grants.
World Leading Long Duration Energy Storage Technology
Sunlands Power is responsible for the manufacture of TES Graphite Cells that utilise Uley 2 coarse graphite as the essential raw material and critical component underpinning the world leading performance of TES Graphite Cells.
These cells represent the only available technology capable of creating supercritical steam at a scale to drive commercial, industrial and utility-scale turbine generators. The technology offers coal-fired generators a viable path to retrofitting their facilities and achieving emissions-free generation. As a grid network tool, the technology has a capability (e.g., grid forming, voltage and frequency control) unmatched compared with existing technologies such as synchronous condensers.
