In this deep-dive, we go through and analyse all of the technical features and claims of CATL’s new sodium-ion grid-scale BESS product, including its ‘millisecond-level self-healing’.

BESS has huge potential to be deployed alongside AI data centres, but how are industry players positioning themselves to capture this opportunity?

We analyse recent details that have emerged on battery OEM CATL’s zero-degradation BESS technology, which was first announced two years ago.

Liam Critchley takes a deep dive into battery state of health (SoH), one of the most important metrics for battery storage operational and lifecycle management.

State of charge (SOC) is on the face of it a straightforward measurement for batteries and BESS. But in reality, it’s highly complex and under- or over-reporting still happens in the industry, leading to under-performance and losses in revenue.

We go through the main movers and shakers commercialising large-scale thermal energy storage technologies today.

Liam Critchley examines the modelling, safety standards and analytics that aim to mitigate the risk of thermal runaway in lithium-ion battery energy storage systems (BESS).

Liam Critchley examines a selection of third-party technologies for preventing thermal runaway events in battery storage systems.

Solar-plus-storage projects are proliferating across the globe and necessitate a choice between DC and AC coupling. In this piece we look at the differences and pros and cons of each.

What are the different types of AC and DC augmentation in battery storage, and the pros and cons of each?
