Around 4.9GW/14.6GWh of large-scale BESS came online in May, with a much more balanced regional breakdown than usual.

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).

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

A total of 4.5GW/12.8GWh of large-scale BESS capacity when into operation around the world last month, with Asia and South America showing strong figures.

Lithium-ion battery cell degradation is one of the things that makes BESS a more complicated asset to manage than other clean energy technologies.

We hear from industry sources about the significance of the CATL-HyperStrong sodium-ion BESS battery deal. Does it make a real turning point for the technology as an alternative to lithium-ion?

With CATL and HyperStrong’s 60GWh sodium-ion battery deal announcement yesterday, it’s an ideal time to look at the different sodium-ion cell chemistries and battery products available for BESS today.

We look at the potential of flow batteries for LDES and compare the leading providers’ offerings and trajectories.

Building BESS is complicated, with myriad considerations around supplier contracts, site acceptance tests, data analysis, interface between different contractors.

How can the industry prepare for when the first wave of utility-scale BESS projects begin to reach end-of-life?
