How to build a potential energy battery ?

[Yonatan shalev]

Hello,
I want to build a green energy storage system. Where an engine lifts a big mass with the electric energy that is available at the moment, i.e solar/wind/grid. Then release the mass from about 30m - 50m to create an electric energy. Was thinking to use gear transmission to control the speed of the system energy discharge and electric voltage.

will appreciate an advice on the following:
1. How to I calculate the potential electric energy using the height and mass.
2. I also want to be able to calculate the time of discharge VS gear transmission VS mass VS height.
2. any recommendation of a design and parts type to purchase (turbine, dynamo, engines, gear transmission set etc.) will be appreciated.

thanks!

Hi and welcome to the forum.

Do you have this idea in mind?

yes, very similar.
any ideas o the calculations i asked about?

The most flexible way is to move water. You can move a little or a lot, depending on how much power is available at that time. Store it above, then use it through a water turbine when needed.
