Hithium Energy Storage Technology has introduced its latest long-duration energy storage (LDES) solution, the ∞Power 6.9 MWh 8-hour energy storage system, marking a significant expansion of its global clean energy strategy.
The system was unveiled at the “Powering The Long Game” event in Sydney, where industry experts and clean energy stakeholders gathered to discuss the future of large-scale energy storage and grid stability. The launch highlights Australia’s growing role as a key market for long-duration storage technologies.
The new system is designed specifically for 8-hour discharge applications, positioning it beyond conventional short-duration battery storage solutions. Unlike adapted 4-hour systems, the ∞Power platform has been engineered from the cell level to its thermal management architecture to support sustained energy output.
Equipped with 1300 Ah LDES-dedicated cells, the system delivers 6.9 MWh of capacity within a standard 20-foot container and is optimized for reduced degradation during extended operation cycles. The design is tailored to meet Australia’s increasing demand for grid reliability as renewable energy penetration continues to rise.
Australia is rapidly strengthening its long-duration energy storage policies. New South Wales has mandated an 8-hour minimum discharge requirement and is targeting 28 GWh of LDES capacity by 2033. Victoria has also updated its energy storage frameworks to support longer-duration systems, reinforcing national momentum toward grid-scale energy resilience.
During the event, energy experts emphasized that 8-hour storage is becoming essential infrastructure for balancing renewable-heavy power grids. Wendel Hortop, Head of Australia at Modo Energy, noted that Australia is emerging as a global pioneer in LDES adoption due to strong policy support and market demand.
A technical panel discussion featuring industry leaders highlighted growing investor interest in long-term storage partnerships. Jay Che stressed that developers are increasingly prioritizing lifecycle efficiency, system reliability, and integration flexibility when selecting energy storage solutions.
Hithium said the launch reflects its commitment to advancing long-duration energy storage technologies and expanding localized support across Australia and the Asia-Pacific region. The company emphasized that LDES systems will play a central role in supporting grid stability, renewable integration, and the transition toward cleaner energy systems.
The introduction of the ∞Power system strengthens Hithium’s position in the global energy storage market as demand grows for scalable, long-duration solutions capable of supporting next-generation power grids.
