Hydrogen storage

Efficient storage and safe transport

ENG_quadrate-web-einzeln_02

The safe and efficient storage of hydrogen is hitherto an unsatisfactorily resolved difficulty in dealing with hydrogen. Due to its low density hydrogen typically needs to be highly compressed. This results in greater complexity with regard to energy demands, and the requirement of constructing a completely new infrastructure (compressed hydrogen gas stations, etc.).

Significant progress has been made over the past few years in a novel method of hydrogen storage by researchers at the FAU Erlangen-Nürnberg. Using the so-called liquid hydrogen carriers (LOHC), even large amounts of hydrogen can be saved, stored and transported without loss and at ambient conditions.

This technology will be developed further by researchers at FAU Erlangen-Nürnberg within the scope of the subproject Efficient energy storage and safe transport. The focus will be on the stationary application as long-term storage for renewable energy. The operating principle of a decentralized functional storage facility will be revealed as part of a demonstration system (see menu item “Demonstrator”).

Further systems which are suitable for the storage of hydrogen will also be considered in this subproject. Emphasis will be put on supported hydrides, adsorptive storage, and the use of hydrogen for the synthesis of short-chain alcohols.

Subproject II

Subproject II encompasses the following research topics: Liquid Organic Hydrogen Carrier technology LOHC (TP II.1), storage of hydrogen in supported hydrides (TP II.3.1) and by adsorption (TP II.3.2), along with the synthesis of short-chained alcohols (TP II.3.3).

LOHC-Technology

Principle: Storage of hydrogen (H2) using energy-bearing (hydrogen carrier) materials

LOHCs (Liquid Organic Hydrogen Carriers) are studied at the BHC (Bavarian Hydrogen Center) as energy-bearing materials. Hydrogen which is chemically bonded to the carrier material during hydrogenation (loading) can be released selectively by dehydrogenation (unloading).

Using this new technology, large amounts of hydrogen can be economically and safely stored and transported at ambient conditions.
