Coal is also energy storage, well, all fossil fuels. That’s their primary advantage, on-demand easily accessible stores of energy.
If only they didn’t simultaneously pollute and cook the earth when used…
Comment on A huge battery has replaced Hawaii's last coal plant

Wasn’t very clear but the battery will be charged using existing renewable sources.
The headline is poorly worded since coal is energy production and batteries are energy storage.

They are stored solar energy! Releasing the energy also unfortunately releases the carbon into the atmosphere.

No, the plant is full of primary batteries! 4.2 million AA cells!

in terms of usage though, they are quite similar. Coal serves on-demand power, whereas renewables generate power at times that don’t always align with demand. Batteries can take the role of a coal plant if the renewables already generate sufficient energy.

all our “energy production” just converts energy from one state into another

I assume they used to fire up the coal plant to fill gaps but now use the battery which stores excess energy generated.
