• ​Gravitricity is a fast, versatile energy storage system.

  • A long lasting battery.​

• Take old, used mine shafts and suspend a cylindrical, 3000 ton weight. 

  • When there is excess power it will be raised.

  • When power is needed it will be lowered slowly, or dropped quickly to generate power.

• The main cost will be the actual holes, using existing mine shafts initially will greatly lower the cost.

  • ​Stated as cheaper than lithium batteries.​​

• As intermittent renewable energy production goes up, more effective ways to store energy are required.

• The system is still in the design phase.

• The company will be creating a concept design over the next 12 months. They plan to implement a full-scale prototype in 2019 or 2020 at a disused mine in the UK.

• Similar in design to current water pumping storage systems, but are more versatile.

• 50-year design life, with no cycle limit or degradation.

• Likely will stick around.

  • Gravitricity awarded £650k funding from Innovate UK's Infrastructure Systems Innovation competition​.

  • International Energy Agency estimates the capacity of energy storage should increase from 140 GW in 2014 to 450 GW by 2050
