the reason why electrical equipment cannot store energy

Battery Energy Storage: How it works, and why it''s important
The need for innovative energy storage becomes vitally important as we move from fossil fuels to renewable energy sources such as wind and solar, which are intermittent by nature. Battery energy storage captures renewable energy when available. It dispatches it when needed most – ultimately enabling a more efficient, reliable, and
Electrical Hazards
Lockout is a physical way to ensure that the energy source is de-energized, deactivated, or otherwise inoperable. Tagging tells others that the device is locked out, who has locked it out, and why. Tagged devices and systems must not be re-energized without the authority of those named on the tag. There are four documents in this series.

Why Can''t We Store AC in Batteries instead of DC?
We cannot store AC in batteries because AC changes their polarity up to 50 (When frequency = 50 Hz) or 60 (When frequency = 60 Hz) times in a second. Therefore the battery terminals keep changing i.e. Positive (+ve) becomes Negative (-Ve) and vice versa, but the battery cannot change their terminals with the same speed so that''s why we can
