Abstract Liquid organic hydrogen carrier (LOHC) systems offer a very attractive method for the decentralized storage of renewable excess energy. In this contribution, industrially well-established heat-transfer oils (typically sold under trade names, e.g., Marlotherm) are proposed as a new class of LOHC systems. It is demonstrated that the liquid mixture of isomeric dibenzyltoluenes (m.p. −39 to [...]
Abstract Organic hydrogen carriers show a great potential as future energy storage systems. Limitations of the dehydrogenation step due to thermodynamic limitations are one of the major challenges. Based on the reaction equilibria for some example compounds the feasibility of certain substance classes is discussed.
Abstract Chemical conversion is a key technology for hydrogen storage. Two basic options exist in this field: reversible storage using organic carrier materials (energy carrying compounds) and irreversible conversion into hydrocarbon fuels (gas-to-fuel). It has been shown that reversible storage exhibits significantly higher overall storage efficiency for the electricity-to-electricity storage process. The high storage density [...]
Liquid Organic Hydrogen Carriers as an efficient vector for the transport and storage of renewable energy
Abstract This contribution proposes the usage of Liquid Organic Hydrogen Carriers (LOHC) for the storage and subsequently the transport of renewable energy. It is expected that a significant share of future energy consumption will be satisfied with the import of energy coming from regions with high potential for renewable generation, e.g. the import of solar [...]
Abstract This contribution proposes the usage of Liquid Organic Hydrogen Carriers (LOHC) for the establishment of a decentralised energy storage network. Due to the continually increasing amount of renewable energy within the power grid, in particular in countries of the European Union, a huge demand for storage capacities develops that can hardly be met by [...]
Abstract Reconstructing current energy infrastructures dominated by fossil fuels towards a high share of renewable energy requires a drastic extension of energy storage capacities. Common storage technologies like compressed air or pumped hydro are either limited in capacity or have to face low efficiencies. A promising alternative is proposed with the use of energy carrying [...]
Abstract This contribution describes a concept for the establishment of a competitive energy distribution network based on Liquid Organic Hydrogen Carrier (LOHC) compounds. These compounds are characterized by the fact that they can be loaded and un-loaded with considerable amounts of hydrogen in a cyclic process. This concept links the technical challenge of storing temporary [...]
