Description
Das erfindungsgemäße Verfahren beschreibt ein wirtschaftliches Verfahren, Wasserstoff als Hydrid gefahrlos zu speichern und in wasserstoffbetriebenen Kraftmaschinen als Reserve mitzuführen. Die Anwendung von Hydriden für diesen Zweck ist ebenfalls Bestandteil des erfindungsgemäßen Verfahrens.The process according to the invention describes an economical process, hydrogen as Store hydride safely and as a reserve in hydrogen-powered engines to carry along. The use of hydrides for this purpose is also part of the inventive method.
Nach dem Stand der Technik wird Wasserstoff derzeit unter hohem Druck in Tanks, die Platinmetalle als Wasserstoffspeichermedien enthalten, gefahrlos gespeichert. Im Gegensatz zu Maschinen, die mit Otto- oder Dieselkraftstoff betrieben werden, ist das Mitführen einer Kraftstoffreserve an ein Speichermedium für Wasserstoff gebunden. Ein Reservetank wäre im Falle einer wasserstoffbetriebenen Krafimaschine als zusätzlicher Platintank denkbar. Dies wäre jedoch nur unter erheblichen Nachteilen wie hohe Kosten, zusätzliches Gewicht, zusätzlicher Raumbedarf, realisierbar.According to the prior art, hydrogen is currently under high pressure in tanks that Contain platinum metals as hydrogen storage media, stored safely. In contrast to machines that run on petrol or diesel fuel is one Fuel reserve tied to a storage medium for hydrogen. A reserve tank would be conceivable as an additional platinum tank in the case of a hydrogen-powered motor vehicle. However, this would only be with considerable disadvantages such as high costs, additional weight, additional space required, realizable.
Das Mitführen von Wasserstoff in einer Druckgasflasche als Krafistoffreserve birgt hohe Risiken (Explosion) und ist deshalb nicht realisierbar. Auch ist die Zahl der Wasserstofftankstellen noch gering, was den Aktionsradius von wasserstoffbetriebenen Fahrzeugen einschränkt. Die erfindungsgemäße Lösung, den Wasserstoff als Hydride mitzuführen, bietet den Vorteil, daß die Hydride in geeigneten Gefäßen relativ gefahrlos zu händeln sind und deshalb an vielen Stellen, z. B. an normalen Kraftstoff-Tankstellen, zum Verkauf angeboten werden können. Die Anwendung von Hydriden als Wasserstoffspeichermedium für wasserstoffgetriebene Kraftmaschinen ist ebenfalls Bestandteil des erfindungsgemäßen Verfahrens.Carrying hydrogen in a pressurized gas bottle as a fuel reserve harbors a high level Risks (explosion) and is therefore not feasible. Is also the number of Hydrogen filling stations are still small, which is the range of action of hydrogen-powered Vehicles. The solution according to the invention, the hydrogen as hydrides has the advantage that the hydrides are relatively safe in suitable vessels are trading and therefore in many places, e.g. B. at normal fuel filling stations, for Can be offered for sale. The application of hydrides as Hydrogen storage medium for hydrogen powered engines is also Part of the method according to the invention.

Titanhydrid) zum Einsatz.Coming as pressureless hydrogen storage media for the method according to the invention preferably salt-like hydrides from the groups of the alkali metal hydrides (e.g. sodium hydride, Potassium hydride), alkaline earth hydrides (e.g. calcium hydride), mixed hydrides (e.g. Sodium borohydride, sodium aluminum hydride) and alloy-like hydrides (e.g. Titanium hydride).
Die genannten Hydride sind stabile Verbindungen, aus denen durch geeignete chemische oder physikalische Reaktionen Wasserstoff freigesetzt werden kann.The hydrides mentioned are stable compounds from which suitable chemical or physical reactions hydrogen can be released.
Der Reservetank besteht bevorzugt aus einem Behältnis, das eines oder mehrere der o. g. Hydride enthält.The reserve tank preferably consists of a container that holds one or more of the above. Contains hydrides.
Die Wasserstofffreisetzung geschieht im Falte der salzartigen Hydride bevorzugt durch chemische Reaktion mit einem geeigneten, vorzugsweise flüssigen, Reaktionspartner. Dieser Reaktionspartner wird bevorzugt in einem zweiten Behältnis gelagert und kann durch gezielte Dosierung, z. B. automatisch durch Druckregelung, zum Hydrid dosiert werden und dadurch die Wasserstofffreisetzung auslösen. Der entstandene Wasserstoff kann über eine Verbindungsleitung in den Wasserstofftank überfährt und von dem dort befindlichen Speichermedium aufgenommen werden. Er kann auch in einen kleineren Platin enthaltenden Tank überführt und dort als Brennstoff gespeichert werden. Bevorzugt wird Wasser als Reaktionspartner eingesetzt.The release of hydrogen occurs preferentially in the fold of the salt-like hydrides chemical reaction with a suitable, preferably liquid, reaction partner. This Reaction partner is preferably stored in a second container and can be targeted Dosage, e.g. B. automatically dosed by pressure control to hydride and thereby trigger the hydrogen release. The hydrogen generated can Connecting line runs over into the hydrogen tank and from there Storage medium can be recorded. It can also be contained in a smaller platinum Tank transferred and stored there as fuel. Water is preferred as Reaction partner used.
Im Falle der legierungsartigen Hydride wird der enthaltene Wasserstoff vorzugsweise durch physikalische Methoden, bevorzugt durch Temperaturerhöhung auf größer 100°C, freigesetzt. Bevorzugte Energiequelle für die Temperaturerhöhung ist die Batterie.In the case of alloy-like hydrides, the hydrogen contained is preferably through physical methods, preferably by increasing the temperature to greater than 100 ° C, released. The preferred energy source for the temperature increase is the battery.
Bei erfolgtem Druckabfall im Haupttank wird die chemische oder physikalische Wasserstoff- Entwicklung in Gang gesetzt und der entstandene Wasserstoff in den Wasserstofftank überführt. Die Überführung in den Wasserstofftank wird vorzugsweise automatisch durch das entstandene Druckgefälle ausgelöst.If there is a pressure drop in the main tank, the chemical or physical hydrogen Development started and the resulting hydrogen in the hydrogen tank transferred. The transfer into the hydrogen tank is preferably carried out automatically by the created pressure drop triggered.
