Das Verfahren wird analog zu den bekannten Pumpspeicher Kraftwerken zur Speicherung elektrischer Energie und zur Stabilisierung der Stromnetze eingesetzt. The method is used analogously to the known pumped storage units for storing electrical energy and for stabilizing the power grids.

Die Masseträger haben die Form eines Quaders mit den Kantenlängen H × B × T = 5 × 3 × 3 m, das ergibt ein Volumen von 45 m 3 . The mass support in the form of a rectangular parallelepiped with edge lengths H × W × D = 5 × 3 × 3 m, which gives a volume of 45 m 3. Das Gesamtgewicht eines Masseträgers wird mit 45 m 3 × 7,9 t/m 3 ~ 360 t angenommen. The total weight of the bulk support is with 45 m 3 × 7.9 t / m 3 ~ 360 t accepted. Das Anheben der Masseträger um 100 m kann mit heutiger Technik erreicht werden. The raising of the mass support by 100 m can be achieved with current technology.

    Die Grundfläche eines Speichermoduls beträgt 3 × 3 m ~ 10 m 2 . The footprint of a memory module is 3 m × 3 ~ 10 m 2. Auf einem ha Grundfläche können somit ca. 1000 Speichereinheiten errichtet werden. On a hectare base area about 1,000 storage units can thus be constructed. Das entspricht einer potentiellen Energie in Höhe von ca. 1.000 × 100 kWh = 100.000 kWh = 100 MWh. This represents a potential energy of approximately 1,000 x 100 kWh = 100,000 kWh = 100 MWh.
