Tesla was one of the pioneers of the grid-scale battery storage market, but has faced increasing competition in the past few years. In this article we look under the hood of its latest grid-scale BESS product, the Megapack 3. 

In May, US automotive group Ford made the surprise announcement that it was launching a BESS product via new division Ford Energy. In this deep dive article, we look at its product’s specifications and how they compare to other existing solutions.

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. 

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.
