    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.

      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…

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

      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, just at the wrong times.

      All our “energy production” just converts energy from one state into another. Like a battery.

      A dam is often referred to as a giant gravity potential energy battery.
