UNSW Sydney research identifies long-duration batteries as essential to future energy infrastructure
Current battery storage faces limitations during low solar and wind output
Study highlights importance of affordable and scalable solutions for energy reliability
Research from the University of New South Wales (UNSW) Sydney outlines a key factor in energy transformation across Australia’s clean energy sector. The findings focus on battery storage technology, particularly the requirement for long-duration storage systems capable of delivering consistent power during gaps in solar or wind availability. This insight holds relevance for companies across the ASX index Clean Energy Index and other sustainability-focused segments of the Australian market.
Storage Capacity Key to Energy Stability
The report outlines that while battery deployment has grown, most current technologies provide storage over short intervals. In periods of low renewable output, this limitation creates challenges for grid stability. Long-duration batteries could help bridge the energy supply gap during extended periods of cloud cover or low wind conditions, which standard short-duration batteries may not fully address.
Costs Remain a Barrier for Scale
According to the university’s research, the cost per kilowatt hour remains relatively high. This pricing continues to challenge widespread implementation of advanced storage systems. Lowering these costs will be essential for expanding battery storage and achieving broader clean energy targets tied to the ASX-listed renewables and utilities sectors.
Long-Duration Batteries Enhance Grid Reliability
These batteries are designed to release stored energy over many hours or even days, supporting electricity networks during demand spikes or supply shortfalls. The reliability offered by this type of technology strengthens its role in national energy strategies aimed at reducing dependence on fossil fuels. The ability to store and dispatch clean energy reliably also has implications for broader investment in renewable generation infrastructure.
Academic Sector Supports Energy Infrastructure Evolution
With institutions like UNSW Sydney contributing research toward scalable, clean technologies, academic collaboration with the private sector remains a key factor. The integration of findings such as this into national frameworks is shaping the trajectory of companies listed on indexes including the ASX Clean Energy and ASX Utilities.
