Did you read the article? This isn't gravity storage, they're making big capacitors by taking advantage of the way carbon black spreads into closely-spaced pockets when added to cement. It would be part of an electrical circuit.

I'm not saying it's a good idea; I'm not an electrical engineer, so I can't really assess the benefits and risks. But I don't think it's the thing you're complaining about.
