What are the technology improvements of the 4th generation of LFP batteries, and what do they mean for BESS applications?

Elestor claims its hydrogen-iron flow battery delivers 75%+ round-trip efficiency, a 20-25 year lifespan, and 15€/kWh capex for long-duration storage. 

How do Chinese OEMs respond to evolving customer requirements and new risks that come with business outside their home market? We sat down with executives from Rept Battero at Intersolar in June to discuss. 

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’.

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

Some 9.1GW/33.5GWh of large-scale BESS came online globally last month, with Saudi Arabia accounting for over one-third of the figure.

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.

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).
