Yeah it’s a bit confusing. When I hear “battery capacity” I think about GWh not GW but I suppose it isn’t “wrong” as it can mean output “capacity” and they did mention “in GW”

Not sure where you’re getting the numbers from but I think @DarthFrodo@lemmy.world is right here as in the differences in numbers are probably explained by the fact that the first number is only for batteries used to balance the grid and the other one is more general.

But yeah you do make a good point that we have no clue about actual storage capacity. Still, really strange that EU numbers are so low. I expected way more.

I don’t really get it, in the chart “Installed grid-scale battery capacity in gigawatts, 2025”

Europe barely has like 17GW in total but later on below they say:

In Europe, it sees batteries that are already online or nearing completion as likely to benefit most, with capacity seen rising from about 50 gigawatts in 2025 to 75 gigawatts by year-end.

What is this big discrepancy? Is the second part talking about batteries not connected to the grid or something (not grid-scale?)
