HiTHIUM Unveils 6.9MWh 8-Hour BESS at All Energy Australia
Melbourne – October 29, 2026 -- HiTHIUM showed a 6.9MWh, 8-hour-native battery energy storage system (BESS) at All Energy Australia on October 28, claiming that a purpose-built 8-hour system undercuts two 4-hour systems by about 23% on cost.
CSIRO analysis puts the 8-hour cost advantage at 23%
HiTHIUM cited CSIRO GenCost analysis showing that two 4-hour systems delivering the same 8-hour output would cost about 23% more than a purpose-built 8-hour system. The company also pointed to Australian market data: 4-hour-plus high-price events accounted for over 70% of scarcity revenue in 2025, shifting storage value toward firm supply duration.
Policy demand is building. The federal Capacity Investment Scheme (CIS) supports dispatchable clean energy projects, while New South Wales continues to advance dedicated long-duration energy storage (LDES) tenders for projects of eight hours or longer.
