So it was designed for this mine I guess?
I'm not sure there's a lot of mine you're going down filled up, the images I have in mind are quite the opposite, but that's a really cool idea!
There actually is some design to stock energy this way, with weights you lift while having excess energy
Depends on the scale of "going down". Many mines are in the mountains and the material has to be brought down to lower elevations. The mine entry may be lower than the nearest pass but still a lot higher than the destination of the ore.
Open pit is much more common for this type of equipment and it’s basically a reverse mountain. Still might be enough regenerative braking from just the weight of the truck though.
In that case no, because it'd be bringing the weight of the truck and the ore with it.
An open pit at an elevation of 1.5km still means the bottom of the pit could be 1km higher than the place the ore is processed at
If you're thinking of that CGI crane lifting concrete blocks, it's unfortunately a really bad idea.
Pumped hydro stores energy by lifting weight uphill, instead. Water is basically the cheapest thing you can get per tonne, and is easy to contain and move.
To store useful amounts of energy using gravity, you need pretty large elevation differences and millions of tonnes of mass to move.
I love that I knew this conversation was going to happen as soon as I read the article.
And, yes.
