Solar-plus-storage projects are proliferating across the globe and necessitate a choice between DC and AC coupling. In this piece we look at the differences and pros and cons of each.

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

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

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.

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.

Form Energy, Noon Energy and Ore Energy are all commercialising proprietary 100-hour battery technologies for LDES applications, but how do they compare on metrics like cost, energy density and round-trip efficiency? We look at what they have revealed, as well as what they haven’t.
