A growing industry trend towards larger battery cell sizes and higher energy density containers is contributing significantly to falling battery energy storage system (BESS) costs.
Some long-duration energy storage (LDES) technologies are already cost-competitive with lithium-ion (Li-ion) but will struggle to match the incumbent’s cost reduction potential.
After a difficult couple of years which saw the trend of falling lithium battery prices temporarily reverse, a 14% drop in lithium-ion (Li-ion) battery pack cost from 2022-2023 has been recorded by BloombergNEF.
The global energy storage market will grow to a cumulative 942GW/2,857GWh capacity by 2040, attracting US$620 billion in investment, caused by sharply decreasing battery costs, according to a Bloomberg NEF (BNEF) report.
The rise of energy storage will enjoy a similarly meteoric trajectory to that enjoyed by solar PV deployment in the past and could reach 305GWh of installations by 2030, BNEF has predicted.
