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?

Over 1.4GW/3.4GWh of grid-scale BESS came online in Europe, likely its best month ever, accounting for almost a fifth of global figures.

What does the combination of regulatory, supply chain and market pressures mean for the cost of building large-scale BESS this year?

We analyse and compare the metrics of the various LFP battery cells of 587Ah and above, from leading providers CATL, Eve Energy, Hithium, Rept Battero, CALB and BYD.

Ex-Fluence alumnus Marek Kubik sat down with Energy-Storage.news at last month’s Energy Storage Summit 2026 in London to talk big picture BESS technology trends, including energy density, LDES and sodium-ion.
