Gravity-based energy storage tower developer notches a customer order 7

[cmoreride]

Energy Vault signed a $520 million deal to supply 1.6 GWh of energy storage to DG Fuels to produce renewable hydrogen and a variety of fuels.

DG Fuels appears to be a totally legitimate company.

Crazy!!

I considered a multi-ton block in the back-yard gravity storage until I figured out the absolutely puny amount of energy one could store that way, not to mention the potential hazards associated.

Be interesting to see how it works out.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

 

Good luck.

p.s., what's the carbon footprint of all that construction, not to mention all the new diesel-powered monster pickups their employees will all soon be purchasing?

They have yet to build a full-scale tower of blocks like their graphics show, or at least they don't have pictures of it done yet. It appears all they have done from the pictures is a stack of 4 levels ending with 1 block at the top.

The graphics show what must be 40-60 levels of blocks but from their pictures of the EV1 full size test site it appears they can maybe get 10 levels of block under the tower. The tower appears to be around 200' tall and each block is maybe 20' tall.

Their claim is each block stores 1MW of energy. The stored energy is Joules so maybe the wattage is determined by the rate they are dropped? The blocks moved near the bottom will only get lifted a level or two so they certainly don't store very much energy compared to ones that go from the outer ground level to the top of the inner "charged" tower.

hey, they have graphics, even video showing it working. What more do you need ??

And to monitor the power output in real-time ;-)

LOL, that shows about 40 levels of blocks in the stack, but the pictures of their "grid scale" tower can't use more than about 10 levels. The way they move from outer to inner stack, they won't be able to use the first few levels for storage because they are the same height. So, that would leave about 8 levels for storage.

That.video shows a wind farm. How do they expect to be able to precisely place blocks in high winds?

Hmmmmm. How do we square this with the fact that 8% of world carbon emissions is caused by concrete production?

Easy piesy !!! ....... We use crushed cars !!!! Sure, there may be a problem stacking them and they will coat the countryside with rust .... But no concrete will used !!!

Our team of seasoned MBAs and PMPs will hire a brand-new STEM engineer, fresh from 2 year community college to figure out the stacking issues !!!!

Not a problem !!!!

Well, that'll work till all the ICE cars are used up. Don't wanna be crushing those battery cars

Couldn't be bothered to pull off the high value aluminium wheels...low hanging fruit.

and then account for the weight change as they rust.

and the environmental impact of said rust ...
and all the miscellaneous things inside the cars ...

another day in paradise, or is paradise one day closer ?
