Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Anordnung zur Speicherung zeitweise überschüssiger Energie, z. B. aus Windkraftwerken, die bei höherem Bedarf wieder entnommen werden kann.The invention relates to a method and an arrangement for temporarily storing excess energy, eg. B. from wind power plants, which can be removed again at higher demand.
Die verfahrenstechnische Grundlage ist der bekannte wärmetechnische Kreisprozess aus der Verdichtung eines unter Umgebungstemperatur gasförmigen Arbeitsmediums bis zur Kondensation, Speicherung des Kondensats und Energierückgewinnung aus dem wieder vergasten, unter Druck stehenden Arbeitsmedium. Bei der Verdichtung wird Wärme frei, die bei der Vergasung möglichst vollständig wieder genutzt werden muss, um die energetischen Verluste niedrig zu halten.The procedural basis is the well-known thermal cycle from the compression of a gaseous working medium under ambient temperature to condensation, storage of the condensate and energy recovery from the recalcitrant, pressurized working fluid. During compression, heat is released, which must be used as completely as possible during the gasification in order to keep the energy losses low.
Stand der TechnikState of the art
Ein bekanntes Verfahren zur Energiespeicherung ist die Nutzung von verdichteter Luft (Pressluft) als Arbeitsmedium. Hier sind für eine größere Energiespeicherung hohe Drücke und/oder große Volumina erforderlich. Verfahren mit einem Arbeitsmedium mit niedriger kritischer Temperatur, wie Kohlendioxyd, besitzen demgegenüber den Vorteil, dass durch die Verflüssigung pro Volumen mehr Energie bei geringem Überdruck gespeichert werden kann.A well-known method of energy storage is the use of compressed air (compressed air) as a working medium. Here, high pressures and / or large volumes are required for greater energy storage. In contrast, methods with a working medium having a low critical temperature, such as carbon dioxide, have the advantage that more energy can be stored at low excess pressure per volume due to the liquefaction.

Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist es deshalb, ein Verfahren und eine neue Anordnung für eine Speicheranlage zu schaffen, das/die einen einfachen technischen Aufbau hat, bekannte preiswerte Druckbehälter für variable Baugrößen nutzen kann und einen technisch einfachen Wärmekreislauf besitzt. Eine weitere Aufgabe ist es, die Temperaturbedingungen und die Wärmeleitung der verschiedenen natürlichen Umgebungen für den Druckspeicher zu nutzen.The object of the invention is therefore to provide a method and a new arrangement for a storage facility that / has a simple technical structure, known cheap pressure vessel for variable sizes can use and has a technically simple heat cycle. Another task is to use the temperature conditions and the heat conduction of the various natural environments for the pressure accumulator.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren nach Anspruch 1 und Anordnungen nach Anspruch 6 oder 7 gelöst. Dementsprechend wird im Verfahren die bei der Verdichtung entstehende Wärme an einem dem Druckspeicher (
Durch diese Verfahrensschritte wird die Wärmekapazität der natürlichen Umgebung genutzt, wodurch aufwendige technische Wärmetauscher entfallen. Die niedrigen Temperaturen in tiefen Gewässern in Kombination mit dem Arbeitsmedium CO2 ermöglicht eine Verflüssigung bei relativ kleinen Arbeitsdrücken im Druckspeicher. Dadurch können als Druckspeicher industriell gefertigte Druckrohre eingesetzt werden.Through these process steps, the heat capacity of the natural environment is used, which eliminates complex technical heat exchanger. The low temperatures in deep waters in combination with the working medium CO 2 allows liquefaction at relatively low working pressures in the accumulator. As a result, industrially manufactured pressure pipes can be used as accumulators.
Die erfindungsgemäßen Anordnungen zur Durchführung des Verfahrens bestehen gemäß Anspruch 6 aus einem Großrohr als Druckspeicher (
Eine weitere Anordnungsvariante nach Anspruch 7 beinhaltet einen Druckspeicher (
Die Hauptvorteile der Anordnungen sind die variable Größe und der einfache Aufbau. Kohlendioxyd ist preiswert verfügbar und wird zum Umweltschutz im Kreislauf gefahren. Besonders geeignet ist die Speicheranordnung für Offshore Windkraftanlagen und Meereswellenenergieanlagen. Ein weiterer Vorteil der Anordnung ist die mögliche variable Dimensionierung und Gestaltung des Wärmekreislaufs in Abhängigkeit von den herrschenden Umgebungsbedingungen.The main advantages of the arrangements are the variable size and the simple construction. Carbon dioxide is available inexpensively and is cycled to protect the environment. Particularly suitable is the storage arrangement for offshore wind turbines and marine energy systems. Another advantage of the arrangement is the possible variable dimensioning and design of the heat cycle depending on the prevailing environmental conditions.
