Energy storage systems come in many forms, leveraging different technology types. A class of electrochemical storage, lithium-ion batteries have established themselves as the industry standard.
But there are many new technologies vying for their market share.
Sodium-ion batteries are widely considered a sustainable and resource-saving answer to future energy storage, while flow batteries offer a viable alternative in long-duration storage applications.
However, the path to commercialization is not a straightforward one.

Australia’s national science agency puts battery chemistries to test in tropical conditions
Researchers from Australia’s national science agency have teamed with Malaysian authorities to explore how different battery chemistries perform under tropical stressors like heat, humidity and corrosion, and what this means for durability, safety and cost-effectiveness.
GES rolls out manganese-hydrogen battery with significant cost edge over lithium-ion
According to GES, the manganese-hydrogen battery it has developed represents an advanced solution for long-duration energy storage. The technology enables energy to be stored for many hours or even days, overcoming the structural limitations of lithium-ion batteries, which are primarily designed for short-duration applications.
Why sodium-ion can’t yet challenge lithium-ion’s reign
A new generation of sodium-ion (Na-ion) battery cells has been launched as an alternative to the virtual monopoly of lithium-ion (Li-ion). Although the technology is unlikely to displace significant Li-ion market share, recent improvements make Na-ion a viable solution for certain niche applications, with potential for wider usage if cost becomes competitive.

Compressed air energy storage enhanced by gravity
Scientists in China have simulated an advanced adiabatic compressed air energy storage, to which they added an elastic airbag with a heavy load situated above it. The energy, exergy, and economic analysis of the system showed that, due to the constant weight of the heavy load, the airbag’s pressure level remains unaltered during operation.
