Description
Energiespeicher auf Basis von Lageenergie durch Auspumpen eines unter Wasser liegenden geschlossenen KieshaufensEnergy storage on the basis of potential energy by pumping out a closed gravel pit lying under water
Es ist bekannt, dass für das Auspumpen eines unter Wasser liegenden Tanks Energie benötigt wird und durch Wiedereinfüllen von Wasser Energie in elektrischen Strom zurückgewandelt werden kann. (Quelle:
Die beschriebene Konstruktion optimiert diese Speichertechnik mit kostengünstigen Materialien so weit, dass eine ökonomische Nutzung des Konzepts möglich ist.The construction described optimizes this storage technology with low-cost materials so far that an economic use of the concept is possible.
Die Konstruktion besteht aus einem Behälter (
Pumpt die Pumpe (
Wenn Strombedarf auftritt, kann das Wasser aus Behälter (
Bei der Konstruktion des Systems wird zuerst eine geeignete möglichst ebene Fläche auf dem Meeresgrund ausgewählt. Diese Fläche kann mit Sand (
Danach wird die Plane über die Schlaufen (
Danach liegt ein mit der Plane (
Abschließend kann über die Plane noch eine Sandschicht als Schutz vor Verletzungen der Plane aufgeschüttet werden.Finally, a layer of sand can be poured over the tarpaulin as protection against injury to the tarpaulin.
Der Behälter (
Es folgt eine Abschätzung der Leistungsfähigkeit des Systems. Befindet sich der Behälter (
E = 1.000.000.000 kg·9,81 N/kg·1000 m
E = 9.810.000.000.000 J
E ~ 10·E12J
E ~ 2,7 GWh = 2.700.000 kWhAn estimation of the performance of the system follows. Is the container (
E = 1,000,000,000 kg · 9,81 N / kg · 1000 m
E = 9,810,000,000,000 y
E ~ 10 · E12J
E ~ 2.7 GWh = 2,700,000 kWh
Das Speicherkraftwerk kann somit 2,7 GWh Strom speichern. Dies entspricht der Energie von einem Windkraftwerkpark mit 22 Windkraftwerken mit jeweils 5 MW, die einen Tag laufen. Die Baukosten sind proportional zur Menge des Schotters. Die Plane an der Oberfläche des Behälters geht genähert mit der zweiten Potenz des Systemradius ein und ist daher gegenüber der Schottermenge, die in dritter Potenz mit dem Systemradius wächst, bei großen Systemen zu vernachlässigen. Bei einem Schotterpreis von 5 € pro Tonne, entstehen Baukosten von weniger als 5 € pro kWh, was um mehrere Größenordnungen unterhalb von Akkumulatoren liegt.The storage power plant can thus store 2.7 GWh of electricity. This equates to the energy of a wind farm park with 22 5 MW wind turbines running one day. The construction costs are proportional to the amount of gravel. The tarpaulin on the surface of the container approaches at the second power of the system radius and is therefore negligible in large systems over the amount of ballast that grows in third power with the system radius. At a gravel price from 5 € per ton, construction costs of less than 5 € per kWh, which is several orders of magnitude lower than accumulators.
