Hydrogenation of Aromatic Ethers and Lactones: Does the Oxygen Functionality Really Improve the Thermodynamics of Reversible Hydrogen Storage in the Related LOHC Systems?

Oxygen
Compounds known as liquid organic hydrogen carriers (LOHCs) offer a promising pathway for storing hydrogen. Beyond the use of pure hydrocarbons, the incorporation of oxygen atoms offers a way to modify thermodynamic properties and potentially improve ...

Intensified swirling reactor for the dehydrogenation of LOHC

International Journal of Hydrogen Energy
Abstract: In the recent advances towards more sustainable global energy supply, H2 is a possible alternative for large scale energy storage. In this view, Liquid Organic Hydrogen Carriers (LOHC) are a class of molecules that allow for easier long term energy storage compared to conventional H2 technologies.

Evaluation thermochemischer Wärmespeicher zur Integration in den LOHC-Prozess

2022
Aufgrund der Abhängigkeit der regenerativen Energiequellen von Umweltbedingungen entsteht oftmals ein zeitlicher Versatz zwischen Bedarfs- und Produktionszeiten. Diese Lücke muss durch den Einsatz von Energiespeichern geschlossen werden. Ein vielversprechender Ansatz ist die Energiespeicherung in Form von Wasserstoff in flüssigen organischen ...

SAFE AND SUSTAINABLE HYDROGEN PRODUCTION USING LIQUID ORGANIC HYDROGEN CARRIERS (LOHCS)

2022
In the definition of a carbon-neutral energy system and chemical production, the use of hydrogen plays a pivotal role. However, considering the risks associated with its storage and transport under cryogenic conditions and/or at high pressure, the employment of low pressures alternatives is urgent. LOHCs represents a safe and efficient option.

Improving Hydrogen Release From Oxygen‐Functionalized LOHC Molecules by Ru Addition to Pt/C Catalysts

ChemCatChem
Bimetallic PtRu/C catalysts have been prepared by depositing Ru onto a commercial Pt/C catalyst and subsequent thermal annealing. Different Pt : Ru ratios of 1 : 1, 2 : 1, 4 : 1, 8 : 1, and 16 : 1 have been investigated with annealing temperatures of 350
