UK's disused mine shafts plan to store renewable energy

• bogle 7y ago
  "Gravitricity develops winch and hoist system to store energy at half the cost of lithium-ion batteries" - Gravitricity, an Edinburgh-based startup. I think Edinburgh has a really good startup scene with a huge bio-quarter and even some space engineering like Skyrora. Skyscanner, a flight search engine, has been the most successful so far, sold to Ctrip for 1.4b UKP.

  "a typical 10MW lithium-ion battery project, capable of releasing 24MW of electricity per hour" What?

  This is a joke Here's an example video to explain if you can't see why - https://www.youtube.com/watch?v=NIhCuzxNvv0 https://www.youtube.com/watch?v=NIhCuzxNvv0 [edit] I know it's a waste trying to talk to the death cult, but surely you can see 12,000 tonnes is just 23 * 23 * 23 meters cube of water. You could pump this up a hill, with a simple pump and a simple pipe into a hole No need for $$$ af mining engineers to work in a mine continuously. In a complex engineering task where pieces are moving everywhere. Fumes can kill. Noisy. You get you have to move the 500 tonne concretes block when it gets to the bottom (and top).... all this machinery needs people.
