Dan Taylor, director of engineering at optimisation and asset management provider Arenko, speaks to Energy-Storage.news about all things data in battery energy storage systems (BESS).

Around 20.4GWh of grid-scale battery energy storage systems (BESS) came online globally last month, bringing the year-to-date (YTD) total to 208GWh.

How similar is the technology of Exa Energy, which just connected a 100MW/1GWh carbon dioxide-based energy storage system to the grid in China, to that of Energy Dome?  

A panel of BESS industry experts discussed the ins and outs of long-term service agreements (LTSAs) at the Battery Asset Management Summit UK & Ireland 2026 yesterday. 

Intilion has just tied up with CATL for sodium-ion BESS deployments in Europe, following Alfen’s similar move in July, while Merus Power tells us it is in the process of integrating with the OEM’s new product. 

Energy-Storage.news Premium speaks with Freeman Hall, CEO of second-life BESS firm B2U Storage Solutions.

Hithium’s recent sodium-ion battery and BESS product launch is the latest in a long line of announcements showing an inflection point for the battery chemistry. But how do its new products compare to other sodium-ion systems out there, and to its own LFP offering?  

Inaccurate state of charge (SOC) measurements can cost battery energy storage system (BESS) operators up to 15% in lost revenue, a persistent issue despite advances in monitoring technology.

James Costello of EORA Energy discusses the shift from supplying battery technology to developing full energy infrastructure projects.

Liam Critchley with an ESN Premium deep dive into availability, one of the most-discussed metrics in battery storage performance.
