That's not how the proposal works. Each car picks up a box of rocks on a hydraulic jack and hauls it up the hill and then sets it down again and gets another one. Maybe the railcar makes 10 or 100 trips during the day.
- adwn 10y agoYes, you're both right. My fault – I misunderstood the ARES concept.
- usrusr 10y agoAll three of you are right: Ares advertises two different concepts, only the one they call "grid storage" uses more ballast than they can fit on their rolling stock. The one they call "ancillary services", intended only for short term grid regulation/stabilisation", uses fixed ballast that is never removed from the trains during regular operation. This is what the first prototype will be.
