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?)
Seems to be the classic GW vs GWh struggle journalists cannot comprehend.
In 2025, the EU added around 12 GW of extra power output from batteries, and about 25 GWh of energy storage capacity to the already existing infrastructure.
Meaning the batteries can output 12 GW of power for more than 2 hours before they are depleted.
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.
Seems like the first number is just grid-scale battery storage, while the second includes home batteries, which grew faster in the last years. Grid scale takes more time to get approval, build, connect.
