Abstract

Solar operated system comprises using one part of an electrical current produced by a photovolatic arrangement to supply a household or for commercial use and using the remainder to recover hydrogen by electrolysis, storing the hydrogen and recycling as electrical energy as required. The process water and cooling water used for electrolysis is introduced in the form of seawater, brackish water, gray or black water, and is treated in a water treatment plant to produce drinking water. The process water is treated in a second treatment stage by electrolysis. Preferred Features: The system is connected to a mains supply or is a stand alone system. Hydrogen is stored in tanks pressurized at 30-300 bar. The hydrogen is converted back into a current using a fuel cell or I.C. engine.

Description

Zugrundeliegende ProblematikUnderlying problems

Bei der Nutzung von regenerativen Energieträgern - wie der Strahlungsenergie der Sonne - stellt sich immer das Problem, dass das Energieangebot nicht konstant ist, sondern mitunter zeitlich stark schwankt. Da elektrischer Strom schlecht speicherbar ist, muss man andere Wege suchen, wie man sowohl in Zeiten hoher als auch niedriger Sonneneinstrahlung eine gleichbleibende Versorgung des Endverbrauchers mit elektrischer Energie sicherstellen stellen kann.When using regenerative energy sources - such as the radiation energy of the sun - there is always the problem that the energy supply is not constant, but sometimes fluctuates greatly in time. Since electrical current is difficult to store, you have to use others Find ways to get one in both high and low sunshine ensure a constant supply of electrical energy to the end user can.

Eine solche Möglichkeit bietet eine Speicherung der Energie in Form von Wasserstoff. Im Vollastbetrieb kann die Leistung der Photovoltaik-Anlage dazu verwendet werden, Wasserstoff zu produzieren, der dann in Zeiten geringer Sonneneinstrahlung (z. B. nachts) beispielsweise über eine Verbrennungskraftmaschine oder eine Brennstoffzelle rückverstromt wird und somit eine ausreichende Stromversorgung garantiert.One such possibility is to store the energy in the form of hydrogen. in the At full load, the power of the photovoltaic system can be used to To produce hydrogen, which is then used in times of low solar radiation (e.g. at night) for example, converted back into electricity via an internal combustion engine or a fuel cell is guaranteed and thus an adequate power supply.

Stand der TechnikState of the art

Am 28.03.2000 wurde vom Antragsteller ein Patentantrag für ein "mit Windkraft betriebenes System zur Gewinnung von Wasserstoff und Trinkwasser einschließlich Wasserstoffnutzung" (Aktenzeichen 100 15 402.6) eingereicht. Das vorliegende System ist insofern eine Erweiterung dieses Patentantrages, als das System nicht nur mit einer Windkraftanlage als Energiequelle betrieben werden kann, sondern auch mit einer Photovoltaik-Anlage, die die Strahlungsenergie der Sonne in elektrischen Strom umwandelt.On March 28 , 2000 , the applicant filed a patent application for a "wind-powered system for the production of hydrogen and drinking water, including the use of hydrogen" (file number 100 15 402.6). The present system is an extension of this patent application in that the system can be operated not only with a wind turbine as an energy source, but also with a photovoltaic system which converts the radiation energy of the sun into electrical current.

Verbesserung des neuen Systems gegenüber bekannten SystemenImprovement of the new system compared to known systems

Bisher gibt es noch keine Kombination einer solar betriebenen Wasseraufbereitung und einem System zur Wasserstoffproduktion, -speicherung und -nutzung. So far there is no combination of solar powered water treatment and one System for hydrogen production, storage and use.  

Das neue Verfahren ermöglicht das Betreiben einer mit einer Photovoltaik-Anlage gekoppelten Wasserstoffproduktions- und nutzungsanlage mit Meer-, Brack- Grau- oder Schwarzwasser.The new process enables operation with a photovoltaic system coupled hydrogen production and utilization plant with sea, brackish, gray or Black water.

Dadurch kann eine Speicherung von elektrischem Strom in Form von Wasserstoff und die anschließende Rückverstromung in Zeiten niedriger Sonneneinstrahlung auch in solchen Regionen problemlos zur Anwendung kommen, in denen kein Trinkwasser zur Verfügung steht (z. B. in Schwellen- und Entwicklungsländern).This can result in the storage of electrical current in the form of hydrogen and the Subsequent re-generation in times of low solar radiation even in such times Regions without problems where drinking water is not available stands (e.g. in emerging and developing countries).

Dort kann man mit dem System gleichzeitig das Problem des Mangels an sauberen Trink- und Brauchwassers, als auch das der unzureichenden Stromversorgung in abgelegenen Gebieten lösen.There you can use the system to solve the problem of the lack of clean drinking and Industrial water, as well as that of inadequate power supply in remote areas to solve.

Beschreibungdescription
