A new and simple pumped-storage hydropower plant

The Keim Power Plant

Instead of using the potential energy of the water in conventional pumped storage hydro power stations, I use high compressed air deep submontane.

The power station is completely under the earth’s surface.

With comparatively little water quantity the very high pressure allows the storage of a lot energy.

Only as startup the compressed air and the water must be filled in.

There must be at least two big underground chambers for the high pressure and the low pressure sides, in between one or two small chambers for the pumps and (pelton-) turbines.

The low pressure chamber must have a funnel to the surface, to avoid pressure rising in it.

Possible main gas reservoirs are old mines, natural (salt-) caverns, man made holes, also in mountains (only the high pressure side must be deep in the rock) or porose rock – even empty natural gas fields for example (there we better take compressed nitrogen gas instead of air).
