Long Duration Energy Storage Trials in Remote Microgrids

Summary

Need

Decarbonising regional microgrids will require storage capable of providing power for more than 8 hours. Finding new technological solutions for bulk energy shifting is critical to allowing unconstrained connection of renewables, such as rooftop solar, without compromising the stability of the power system. 

Energy storage plays a critical role in improving network resilience and reliability by providing backup power during peak demand or when the power supply is interrupted. Long-duration energy storage systems can store high volumes of excess energy during off-peak periods when demand is low and release it gradually during peak periods when demand is high. By providing a buffer between solar power generation and consumption outside solar hours, LDES can help balance the supply and demand of electricity and minimize the need for costly fossil fuel generation and grid infrastructure upgrades. 

Action

Energy storage plays a critical role in improving network resilience and reliability by providing backup power during peak demand or when the power supply is interrupted. Long-duration energy storage systems can store high volumes of excess energy during off-peak periods when demand is low and release it gradually during peak periods when demand is high. By providing a buffer between solar power generation and consumption outside solar hours, LDES can help balance the supply and demand of electricity and minimize the need for costly fossil fuel generation and grid infrastructure upgrades. 

LDES technologies will be installed in remote microgrids to test their performance and ability to minimise solar supply loss by shifting it to evening hours and their temperature resilience. 

Outcome

The objectives for the Project will be achieved through the following Outcomes:  

1. enhancing the value derived from renewable energy by increasing the ability to provide clean dispatchable electricity supply (stored PV supply) and improve control and reliability of renewable energy;  
2. improving the technical readiness of zinc bromine flow and sodium sulphur technologies by acquiring unique technical insights on their performance in remote microgrids;  
3. reducing commercial and regulatory barriers for Australian battery suppliers, increasing regional spend and providing regional job opportunities; and  
4. harmonising the Recipient’s connectivity, control, and connection standards to integrate non-lithium technologies and drive future implementations.
