Is it possible to freeze lightning?
In addition to it being highly impractical, you still aren’t storing much energy. But it does sort of count as freezing electricity. Realistically, the closest we can come to “freezing” electricity is to store it as electric fields (in capacitors) or electrochemically (in batteries).
