Description
Aufgrund der für die Umwelt schädlichen Auswirkungen der Verbrennung von fossilen Rohstoffen, wie etwa Kohle oder Erdgas einerseits und einem wachsenden Strombedarf andererseits, wird versucht andere Stromquellen zu nutzen, wie beispielsweise durch den Einsatz von Windrädern, Wasserkraftwerken oder die Nutzung von Photovoltaikanlagen zur Stromerzeugung und Stromspeicherung.Due to the harmful effects on the environment of burning fossil raw materials such as coal or natural gas on the one hand and a growing demand for electricity on the other hand, attempts are being made to use other sources of electricity, such as the use of wind turbines, hydroelectric power plants or the use of photovoltaic systems to generate and store electricity .
Die aktuelle Bundesregierung hat es sich zum Ziel gesetzt, bis zum Jahre 2025, 40-45 % des in Deutschland verbrauchten Stroms aus erneuerbaren Energien zu schöpfen. Als wichtigste Energieträger werden hierbei Wind und Sonderenergie genannt, zuzüglich deutlich geringerer Stromerzeugung durch den Einsatz von Biomasse und Wasserkraft.The current federal government has set itself the goal of generating 40-45% of the electricity consumed in Germany from renewable energies by 2025. Wind and special energy are mentioned as the most important energy sources, plus significantly lower electricity generation through the use of biomass and hydropower.
Hiervon ausgehend, hat es sich, die nachstehend zu erläuternde Erfindung, zur Aufgabe gemacht, einen weiteren Beitrag nicht nur zur Stromerzeugung, sondern auch zur Stromspeicherung zu leisten.Based on this, the invention to be explained below has set itself the task of making a further contribution not only to electricity generation, but also to electricity storage.
In diesem Zusammenhang ist es beispielsweise schon jetzt aus dem Stand der Technik bekannt, den Dachbereich von Lastwagen mit Photovoltaikzellen, genauer gesagt, mit PV-Modulen (1) zu bestücken, wobei die so gewonnen Energie gespeichert und etwa zur Kühlung oder Heizung der Ladefläche eines Lastwagens eingesetzt werden.In this context, it is already known from the prior art, for example, to equip the roof area of trucks with photovoltaic cells, or more precisely, with PV modules (1), with the energy thus obtained being stored and used, for example, for cooling or heating the loading area of a truck Trucks can be used.
Des Weiteren ist in Australien ein sogenannter „Soltrain“ im Einsatz, dessen Waggons ebenfalls oberseitig, also im Dachbereich mit Photovoltaik bestückt sind, die zur Heizung oder Kühlung des besagten Zuges eingesetzt werden.Furthermore, a so-called “Soltrain” is in use in Australia, the wagons of which are also equipped with photovoltaics on the top, i.e. in the roof area, which are used to heat or cool the train in question.
Ausgehend von diesem Stand der Technik, hat sich der Erfinder es zur Aufgabe gemacht, Züge zu entwickeln, die ebenfalls mit PV-Modulen (1) bestückt sind, wobei es hier darum geht, die mittels der PV-Module (1) gespeicherte Energie bzw. den Strom entweder auf dem Zug zu speichern und zu gegebener Zeit in das Oberleitungsnetz über Schleifbügel oder Schleifleisten einzuspeisen oder aber die Energie direkt in das Oberleitungsnetz einzuspeisen.Based on this state of the art, the inventor has set himself the task of developing trains that are also equipped with PV modules (1). The aim here is to use the energy stored by the PV modules (1). .either to store the electricity on the train and feed it into the overhead line network at the appropriate time via contact bars or contact strips, or to feed the energy directly into the overhead line network.
Darüber hinausgehend, schlägt die Erfindung aber auch vor, etwa auf stillgelegten Strecken, die vorzugsweise regelmäßig einer nennenswerten Sonneneinstrahlung ausgesetzt sind, zu nutzen, um mittels der auf den Zügen befestigten PV-Module (1) Strom zu gewinnen und entweder direkt einzuspeisen oder zu speichern. Denkbar ist es auch, nicht benutzte Züge, die ebenfalls mit entsprechenden PV-Modulen (1) ausgestattet sind, zur Stromspeicherung und Stromeinspeisung zu nutzen.In addition, the invention also proposes using disused routes, which are preferably regularly exposed to significant solar radiation, to generate electricity using the PV modules (1) attached to the trains and either feed it in directly or store it . It is also conceivable to use unused trains, which are also equipped with appropriate PV modules (1), to store and feed in electricity.
Denkbar ist es auch, fahrenden Züge mit entsprechenden PV-Modulen (1) auszustatten, wobei auch ein Teilbereich zum Transport von Passagieren oder sonstiger Ladung genutzt sein kann, indem beispielsweise Abschnitte der Züge ausschließlich mit PV-Modulen (1) zur Stromeinspeisung bestückt sind, sowie auch Waggons zum Transport von Passagieren, Bestandteil der entsprechenden Züge sind.It is also conceivable to equip moving trains with corresponding PV modules (1), whereby a sub-area can also be used to transport passengers or other cargo, for example by having sections of the trains exclusively equipped with PV modules (1) for power supply, as well as wagons for transporting passengers are part of the corresponding trains.
In allen Fällen, werden nur Züge eingesetzt, bei denen sichergestellt ist, dass die über die PV-Modulen (1) gewonnene Energie, deutlich den Energieeinsatz für den Verkehr der Züge überschreitet.In all cases, only trains are used where it is ensured that the energy obtained via the PV modules (1) significantly exceeds the energy used for the trains' traffic.
In diesem Zusammenhang ist es aber auch denkbar, Züge mit PV-Modulen (1) auf stillgelegten Strecken abzustellen, allein um mithilfe dieser abgestellten Züge wiederum Strom zu gewinnen, der in das Netz eingespeist wird.In this context, it is also conceivable to park trains with PV modules (1) on disused routes, simply in order to use these parked trains to generate electricity that is fed into the network.
Das Streckennetz der Bahn beträgt derzeit ca. 38.400 Km + stillgelegte Strecken und Rangierbahnhöfe. Nach derzeitigem Stand der Modultechnik könnten bei einer Nutzung von 10 % der Strecken ca. 2.500 bis 3000 MWh Stunden an Energie gewonnen werden.The railway's route network is currently approx. 38,400 km + disused routes and marshalling yards. According to the current status of module technology, approximately 2,500 to 3,000 MWh hours of energy could be generated if 10% of the routes were used.
Die Bahn will ihre Anlagen bis 2038 zu 100% mit „grünem“ Strom betreiben. Die Erfindung könnte hierzu einen wesentlichen Beitrag leisten. Gemäß dem Stand um Jahr 2021 hat die Bahn einen Energiebedarf von 10 Terawattstunden.The railway wants to operate its systems 100% with “green” electricity by 2038. The invention could make a significant contribution to this. As of 2021, the railway has an energy requirement of 10 terawatt hours.
Züge mit bis zu 700 Metern Länge, gemäß dem Stand der Technik bei Güterzügen, könnten als bewegliche Kraftwerke mit Leistungen von 300 bis 500 KW betrieben werden.Trains up to 700 meters long, according to the state of the art for freight trains, could be operated as mobile power plants with outputs of 300 to 500 KW.
