Hithium Debuts 8-Hour 6.9 MWh Energy Storage System in Australia

Global energy storage provider Hithium has unveiled its ∞Power 6.9 MWh 8-hour energy storage system during the “Powering the Long Game” event in Sydney. The launch marks the company’s entry into Australia’s long-duration energy storage (LDES) market and highlights its commitment to supporting the region’s renewable energy transition.

During the event, Hithium executives and local clean-energy experts explored global LDES trends, emerging market opportunities, and the policy shifts driving grid-scale storage. New South Wales has introduced a minimum eight-hour discharge requirement and is targeting 28 GWh of long-duration storage by 2033. Victoria has also updated its LDES framework, with both states signaling strong policy backing for multi-hour storage solutions.

A keynote address by Wendel Hortop, Head of Australia at Modo Energy, emphasized that as renewable generation expands, eight-hour storage will become vital infrastructure. He noted that Australia is well positioned to take the lead in developing and deploying LDES technologies capable of firming variable renewable supplies.

Designed with these requirements in mind, Hithium’s ∞Power 6.9 MWh system employs 1,300 Ah cells purpose-built for continuous eight-hour discharge. Housed in a standard 20-foot container, the system integrates advanced thermal management and cell-level engineering to minimize degradation during long-duration cycling. It is optimized to meet Australia’s safety, performance, and maintenance standards for grid regulation services.

Following the product launch, a panel discussion led by Jay Che, Hithium’s Director of Application Engineering for Australia and APAC, examined the LDES investment pipeline, grid reliability needs, and the criteria investors use when selecting storage partners. Che highlighted a growing developer preference for partners offering strong lifecycle economics, dependable performance, and flexible integration strategies that strengthen grid resilience.

Founded in 2019, Hithium has scaled its research, production, and service capabilities to achieve more than 100 GWh of cumulative lithium-ion energy storage shipments globally by August 2025. The company continues to invest in localized long-duration solutions and services aimed at accelerating a greener, more reliable energy future in Australia and beyond.
