Definitions
- the invention relates to a storage medium and a method for storing hydrogen.
- hydrogen can be stored in compressed form in corresponding high-pressure accumulators, which allow storage up to a pressure of 875 bar.
- the aforementioned systems have in common that the hydrogen is reacted with them under suitable conditions, so that a hydrogenation and thus storage of the hydrogen takes place.
- a storage medium for storing hydrogen which is characterized in that the storage medium at least one hydrogenatable, ionic.
- the storage of the hydrogen takes place on a storage medium which has at least one hydrogenatable, ionic compound or at least partially consists of at least one hydrogenatable, ionic compound.
- the ionic compounds used are preferably in liquid and / or solid form.
- Hydratable ionic compounds in liquid form are hereafter referred to as ionic liquids.
- hydrogenatable, ionic compounds which are present in solid form are referred to as ionic solids.
- Hydratable ionic compounds are thus ionic liquids or ionic solids that have the ability to chemically bond hydrogen.
- Ionic liquids are low-melting, organic salts with melting points between 100 and -90 0 C, wherein most of the known ionic liquids are already in liquid form at room temperature. In contrast to conventional molecular liquids, ionic liquids are entirely ionic and therefore show new and unusual properties. Ionic liquids can be adapted comparatively well by varying the structure of anion and / or cation and by varying their combinations in terms of their properties to given technical problems. For this reason, they are often referred to as so-called "Designer Solvents". For conventional molecular liquids, however, only a variation of the structure is possible.
- ionic liquids In contrast to conventional molecular liquids, ionic liquids also have the advantage that they have no measurable vapor pressure. This means that, as long as their decomposition temperature is not reached, they do not evaporate in the slightest traces, even in a high vacuum. This results in the properties of incombustibility and environmental friendliness, since ionic liquids can not escape into the atmosphere.
- the melting points of known ionic liquids are by definition below 100 ° C.
- the so-called liquidus range-this is the range between melting point and thermal decomposition-is generally 400 ° C. or more.
- ionic liquids have a high thermal stability. Often their decomposition points are above 400 ° C. The density and the mixing behavior with other liquids can be influenced or adjusted in the case of ionic liquids by the choice of the ions. Ionic liquids also have the advantage that they are electrically conductive and thereby can prevent electrical charging - which represent a potential hazard.
- the term "ionic solids" in the following salts in the sense of the above-described ionic liquids are to be understood, which have a melting point of at least 100 0 C. In addition, there are no principal chemical and physical differences between ionic liquids and ionic solids - as defined above.
- the storage medium according to the invention is reacted with hydrogen under suitable conditions (pressure, temperature, catalysts, introduction of the hydrogen into the ionic liquid, etc.), hydrogenation takes place, as a result of which the hydrogen is stored or bound to or in the storage media according to the invention becomes.
- a discharge of the storage medium according to the invention takes place with liberation of the stored hydrogen.
- this has, according to an advantageous embodiment of the invention, at least one conjugated, preferably aromatic pi electron system.
- This pi-electron system may be in the cationic part, in the anionic part or in both of the above parts; furthermore, several resonant or separate pi-electron systems can also be combined in one molecule. Further stabilization of the pi-electron system of the dehydrogenated form or destabilization of the hydrogenated form - in the thermodynamic sense - is achieved by derivatization with suitable substituents. The interaction of these substituents with the Pi- electron system is effected by inductive, mesomeric and / or field effects.
- the relevant cation (Q + ) n is a quaternized ammonium (R 1 R 2 R 3 R 4 N + ), phosphonium (R 1 R 2 R 3 R 4 P + ) and / or sulfonium cation (R 1 R 2 R 3 S + ) and / or an analogous quaternized nitrogen, phosphorus or sulfur heteroaromatic, where the abovementioned radicals R 1 , R 2 , R 3 and R 4 may be the same, in some cases identical or different.
- radicals may be linear, cyclic, branched, saturated and / or unsaturated alkyl radicals, mono- or polycyclic aromatic or heteroaromatic radicals and / or derivatives of these radicals substituted with further functional groups, where R 1 , R 2 , R 3 and R 4 are also can be interconnected.
- anions it is possible to use all known organic and inorganic anions. According to an advantageous embodiment of the storage medium according to the invention, hydrogenatable anions are used.
- the storage medium according to the invention as well as the method according to the invention for storing hydrogen create a storage possibility for hydrogen, which - compared to the prior art - has a high environmental compatibility and considerable safety advantages.
