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.

Most home battery storage systems meet warranty claims, new research finds It took eight years of field measurements for researchers at the RWTH Aachen University in Germany to estimate the usable capacity of home battery energy storage systems and develop a dataset covering 106 system years and 14 billion datapoints. Their key finding was that home battery systems lose about two to three percentage points of usable capacity per year on average, meaning good news for the industry as most warranties in the market can be met with the implementation of capacity reserves.
