During the tests conducted at the Institute of Military Energy (Germany), studies of an underwater accumulator were performed, which is a concrete sphere located at a depth of 200 meters.
The traditional use of hydraulic accumulating power plants is associated with the use of cheaper electricity to create a water supply (water using pumps is supplied to the tanks over turbines). With an increase in the load in the electric networks and the rise in the cost of electricity, the water is passed through the turbine and produces more expensive energy. Such cycles are most often associated with daily peak loads that arise during the day, and night, calmer loads on energy networks.
During the experiment, a ball of concrete with a diameter of 3 meters was studied. In November 2016, in the Alps, scientists loaded a complex of turbine, pump and concrete sphere to the bottom of Lake Constantess. The experiment took place according to the schedule of traditional accumulating power plants – the water was pumped into the sphere with low network downloading, when the electricity was cheaper. At the time when the peak load on the network arose, and electricity was valued, the water was released from the sphere for rotating the turbine and current production.
According to calculations, the real GEC should be placed at depths of more than 700 meters, and the diameter of the spheres should be 30 m. A sphere located on the bottom of the ocean with a turbine of 5 MW will be able to produce electricity in the amount of 20 MW*hour with full -fledged operation for 4 hours.
If you create a set of such spheres connected to wind stations located in the sea nearby, you can significantly increase the reliability and efficiency of the use of GAES of this type. Economic efficiency is achieved when using a large number of spheres, according to the developers of them, there should be at least 80 pieces. The institute plans to conduct research on areas of larger diameter and in a longer period of time. Investors are already actively interested in the idea of underwater GEPP, despite the fact that before the real incarnation of development is needed for about five years.
In Germany, in the city of Hamburg, it is already planned to use the energy accumulating the energy located in places that do not interfere with others. For this purpose, the Hamburg authorities plan to use natural underground reservoirs, where warm water will be downloaded in the summer, and in winter it will be used for heating.
