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.

Scientists in UK build solar redox flow battery with 9.54% solar-to-chemical efficiency The PV-driven redox flow battery can reportedly achieve a maximum solar-to-output electricity efficiency (SOEE) of 3.11% during a 36-hour period. The system incorporates a 25 sq cm heterojunction (HJT) photovoltaic device and is based on a neutral-pH aqueous iodine-bromine redox couple.
