Gravity energy storage is not actually a new concept. We've been doing it with pumped hydro for more than a century. But that's very expensive to build and needs an awful lot of space. Now though, two new companies have developed systems that mimic the effect of pumped hydro by raising and lowering extremely large and heavy weights up and down over huge height distances. So, do we have yet another addition to the growing grid scale energy storage family?
