Abstract

Die Erfindung betrifft ein Verfahren zur Speicherung von aus fossiler Kohle oder beliebiger Biomasse gewonnenem Wasserstoff. Ein bekanntes Verfahren zur Energiegewinnung aus Kohle ist ein herkömmliches Dampfkraftwerk. Das vorgestellte Verfahren erweitert ein Dampfkraftwerk um einen Kohlevergaser, welcher mit fossiler Kohle oder aus mittels vorgelagerter Hydrothermaler Karbonisierung aus Biomasse hergestellter Braunkohle betrieben wird. Das Kohlenmonoxid der entstehenden Vergasungsprodukte wird über eine Teilanlage zur Wassergas-Shift-Reaktion mit Wasser zu Wasserstoff umgesetzt, das nach optionaler Abtrennung letztlich in einem Gasspeicher gespeichert wird. Das Verfahren hat den Vorteil sowohl konventionell als auch regenerativ betrieben werden zu können.The invention relates to a method for storing hydrogen obtained from fossil coal or any biomass. A well-known process for the production of energy from coal is a conventional steam power plant. The presented method expands a steam power plant by a coal gasifier, which is operated with fossil coal or from lignite produced by means of upstream hydrothermal carbonization from biomass. The carbon monoxide of the resulting gasification products is converted via a unit for the water gas shift reaction with water to hydrogen, which is stored after optional separation ultimately in a gas storage. The process has the advantage of being able to be operated conventionally as well as regeneratively.

Description

Die Erfindung betrifft ein Verfahren zur Speicherung von aus fossiler Kohle oder beliebiger Biomasse gewonnenem Wasserstoff.The invention relates to a method for storing hydrogen obtained from fossil coal or any biomass.

Stand der TechnikState of the art

Vom Erfinder wurde bereits eine Patentanmeldung eingereicht, die eine Kombination eines Kohlevergasers, eines Dampfkraftwerks und eines Wasserstoffmotors zur Energiegewinnung aus Kohle oder, durch vorgelagerte Hydrothermalen Karbonisierung, aus beliebiger Biomasse, mit optionaler Methanolherstellung zum Inhalt hat. Dieses Kraftwerkskonzept kann regenerativ mit vorgelagerter Hydrothermaler Karbonisierung aus beliebiger Biomasse oder konventionell mit fossiler Kohle betrieben werden. Dabei erzeugt die Kohlevergasung einerseits die notwendige Wärme, um ein angeschlossenes Dampfkraftwerk zur Stromproduktion zu betreiben, und andererseits als Abgas eine Kombination von Wasserstoff und Kohlenmonoxid, von dem letzteres mittels einer Wassergas-Shift-Reaktion zu weiterem Wasserstoff umgewandelt wird. Der hergestellte Wasserstoff wird mittels eines Wasserstoffmotors und eines damit betriebene Stromgenerator einerseits zu elektrischem Strom umgewandelt und andererseits die entstehende Abgaswärme des Wasserstoffmotors zur Vorerhitzung des Speisewassers des Dampfkraftwerks genutzt.The inventor has already filed a patent application which has a combination of a coal gasifier, a steam power plant and a hydrogen engine for energy production from coal or, by upstream hydrothermal carbonization, from any biomass, with optional methanol production to the content. This power plant concept can be operated regeneratively with upstream hydrothermal carbonization from any biomass or conventionally with fossil coal. On the one hand, the coal gasification produces on the one hand the necessary heat to operate a connected steam power plant for electricity production, and on the other hand, as exhaust gas, a combination of hydrogen and carbon monoxide, the latter being converted to further hydrogen by means of a water gas shift reaction. The hydrogen produced is converted by means of a hydrogen engine and a power generator operated therewith on the one hand to electric power and on the other hand, the resulting exhaust heat of the hydrogen engine used for preheating the feed water of the steam power plant.

Aufgabenstellungtask

Diese Kombination eines Kohlevergasers, eines Dampfkraftwerks und eines Wasserstoffmotors zur Energiegewinnung zielt einzig auf die Erzeugung von elektrischem Strom ab. Im Hinblick auf einen künftigen verstärkten Bedarf an Wasserstoff, gerade im Mobilitätsbereich, und dem Ziel einer Energiewende aus regenerativen Ausgangsmaterialen bei gleichzeitigem fortschreitenden Ausbau der regenerativen Stromproduktion stellt die Speicherung von Wasserstoff zur weiteren Verwendung eine große Herausforderung der nächsten Jahre dar.This combination of a coal gasifier, a steam power plant and a hydrogen engine for power generation aims solely at the production of electric power. In view of a future increased demand for hydrogen, especially in the area of mobility, and the goal of an energy transition from renewable raw materials with the progressive expansion of renewable electricity production, the storage of hydrogen for further use represents a major challenge in the coming years.

Der Erfindung liegt deshalb die Aufgabe zugrunde sowohl regenerativ als auch konventionell hergestellten Wasserstoff zu speichern, anstatt ihn komplett zu elektrischem Strom umzuwandeln. Das im ersten Verfahrensteil vorgeschlagene Oxidieren von Kohlenstoff, die Nutzung der entstandenen Vergasungswärme in einem Dampfkraftwerk und die Umsetzung von Kohlenmonoxid unter Wasserzugabe in einer Wassergas-Shift-Reaktion soll dabei beibehalten werden, allerdings mit dem Ziel der Wasserstoffspeicherung.The invention is therefore based on the object to store both regenerative and conventionally produced hydrogen, rather than completely convert it to electric power. The proposed in the first part of the process oxidation of carbon, the use of the resulting gasification heat in a steam power plant and the implementation of carbon monoxide with addition of water in a water gas shift reaction is to be maintained, but with the aim of hydrogen storage.

Erfindungsgemäß wird die Aufgabe bei dem Verfahren der eingangs genannten Art durch die im gekennzeichneten Teil der Patentansprüche 1 bis 2 angegebenen Merkmale gelöst. Das Verfahren gemäß der Erfindung hat den Vorteil, dass die Speicherung von Wasserstoff anstelle der vollständigen Verstromung in einer künftige Wasserstoffwirtschaft kostengünstig als Nebenprodukt eines Dampfkraftwerks und mittels vorgelagerter Hydrothermaler Karbonisierung regenerativ möglich wird.According to the invention the object is achieved in the method of the type mentioned by the features indicated in the marked part of claims 1 to 2 features. The method according to the invention has the advantage that the storage of hydrogen instead of the complete power generation in a future hydrogen economy is cost-effectively possible as a by-product of a steam power plant and regenerative by means of upstream hydrothermal carbonization.

Allgemeine Beschreibunggeneral description

Den Hauptbestandteil der Erfindung bilden ein Reaktor zu Kohlevergasung, ein Dampfkraftwerk, eine Teilanlage zur Wassergas-Shift-Reaktion und eine Vorrichtung zur Gasspeicherung. Je nach verwendetem Vergasungsreaktor muss die fossile Kohle in einem vorgelagertem Anlagenteil zu einer gewissen Körnigkeit zerkleinert werden. Bei regenerativem Betrieb aus beliebiger Biomasse muss diese in einem vorgelagertem Anlagenteil in einem kontinuierlichen Durchlaufverfahren oder einem diskontinuierlichen Batchverfahren einer Hydrothermalen Karbonisierung unterzogen werden und wird optional, je nach verwendetem Vergasungsreaktor, mit der Reaktionswärme aus der Hydrothermalen Karbonisierung vor der Vergasung getrocknet. Anschließend wird die zerkleinerte Kohle, der aus Biomasse entstandene Braunkohle-Wasser-Slurry oder der getrocknete Braunkohle-Wasser-Slurry in einem Vergasungsreaktor mit Wasser und (Luft-)Sauerstoff vergast. Idealtypisch entsteht hierbei hauptsächlich Kohlenmonoxid und Wasserstoff durch schnelle Oxidation. Die zu kühlenden Produkte dieses Prozesses erhitzen das Speisewasser im Kessel des Dampfkraftwerks zur Produktion von elektrischem Strom. Das entstehende Kohlenmonoxid des abgekühlte Produktgases des Kohlevergasers wird nun mittels einer Teilanlage zur Wassergas-Shift-Reaktion in Wasserstoff umgesetzt.The main component of the invention is formed by a coal gasification reactor, a steam power plant, a water gas shift reaction unit and a gas storage apparatus. Depending on the gasification reactor used, the fossil coal in an upstream part of the plant must be comminuted to a certain granularity. In the case of regenerative operation from any biomass, it must be subjected to hydrothermal carbonation in an upstream plant section in a continuous flow or batch process and optionally, depending on the gasification reactor used, with the heat of reaction from the hydrothermal carbonization prior to gasification. Subsequently, the comminuted coal, the lignite-water slurry produced from biomass or the dried lignite-water slurry are gasified in a gasification reactor with water and (air) oxygen. Ideally, this mainly produces carbon monoxide and hydrogen by rapid oxidation. The products to be cooled in this process heat the feed water in the boiler of the steam power plant for the production of electricity. The resulting carbon monoxide of the cooled product gas of the coal gasifier is then converted into hydrogen by means of a substation for the water gas shift reaction.

Letztlich wird das entstandene Gasgemisch mit hauptsächlich Wasserstoff in einer Vorrichtung zur Gasspeicherung gespeichert oder mittels einer weiteren Teilanlage der Wasserstoff von den restlichen Gasen getrennt und dann in einer Vorrichtung zur Gasspeicherung gespeichert.Finally, the resulting gas mixture is stored with mainly hydrogen in a gas storage device or separated by means of another subsystem of hydrogen from the remaining gases and then stored in a device for gas storage.

Die Biomasse (1) wird dem Anlagenteil zur Hydrothermalen Karbonisierung (2) zugeführt und nach anfänglichem Beheizen mittels exothermer Reaktion in einen Braunkohle-Wasser-Slurry umgewandelt. Die freiwerdende Wärme wird über eine Wärmekopplung (3) zur anschließenden Trocknung des Braunkohle-Wasser-Slurry (4) verwendet. Darauf wird der getrocknete Braunkohle-Wasser-Slurry im Kohlevergasungsreaktor (5) mit Wasser und (Luft-)Sauerstoff unter Energieabgabe unter anderem zu Kohlenmonoxid und Wasserstoff vergast. Die freiwerdende Wärmeenergie wird dem Heizkessel des Dampfkraftwerksteils (6) zugeleitet. Das dort erhitzte/verdampfte Speisewasser treibt eine oder mehrere Turbinen zur Stromproduktion an. Die Erhitzung des Speisewassers mit den Vergasungsprodukten kühlt diese und diese werden einer Teilanlage zur Wassergas-Shift-Reaktion (7) zugeführt, in der das neben Wasserstoff unter anderem erzeugte Kohlenmonoxid zu weiterem Wasserstoff umgesetzt wird. Vom entstandene Gasgemisch wird hiernach in einer Teilanlage (8) der Wasserstoff von den übrigen Gasen abgetrennt und letztlich in einer Vorrichtung zur Gasspeicherung (9) gespeichert.The biomass ( 1 ) is the part of the hydrothermal carbonisation ( 2 ) and converted after initial heating by exothermic reaction in a brown coal-water slurry. The released heat is via a heat coupling ( 3 ) for the subsequent drying of the lignite-water slurry ( 4 ) used. Then the dried lignite-water slurry in the coal gasification reactor ( 5 ) gasified with water and (air) oxygen with release of energy among other things to carbon monoxide and hydrogen. The released heat energy is the boiler of the steam power plant part ( 6 ). The heated / evaporated feedwater drives one or more turbines to produce electricity. The heating of the feedwater with the gasification products cools them and these are a unit for the water gas shift reaction ( 7 ), in which the carbon monoxide, among other things produced in addition to hydrogen, is converted to further hydrogen. The resulting gas mixture is hereafter in a unit ( 8th ) the hydrogen is separated from the remaining gases and finally in a device for gas storage ( 9 ) saved.
