"Australian long duration energy storage hopeful VSUN Energy says it can
deliver a grid-scale vanadium flow battery with up to eight hours of storage
capacity that can compete, on costs, with lithium-ion battery products
currently in the market.
In a market announcement on Wednesday, parent company Australian Vanadium Ltd
says analysis completed by VSUN Energy finds that a four-hour 100MW vanadium
flow battery energy storage system (BESS) can deliver a levelised cost of
storage (LCOS) of around $A274/MWh.
AVL says the “Project Lumina” analysis compares the estimated LCOS range for a
4-hour and an 8-hour 100MW vanadium flow BESS with that for a 100 MW, 4-four
lithium ion BESS and finds it “competitive,” as the chart below illustrates.
Vanadium flow battery technology offers a number of advantages over the
lithium-ion; starting with their ability to provide the sort of 8-12 hour
storage so desperately needed on modern renewable grids and closely followed by
the sort of longevity afforded by a theoretically unlimited battery cycle life.
“One of the major benefits of VFB BESS, compared to lithium-ion BESS, is their
ability to conduct multiple full and partial charge and discharge cycles per
day without significant degradation over time,” AVL says.
“That flexibility allows the optimisation of the pricing arbitrage between
charge and discharge cycles, as well as increasing the available hours of
discharge potential throughout the day.”
Flow batteries are also considered to be more reliable and safer than their
li-ion counterparts – including being highly resistant to catching on fire."
