“…Hydrogen storage through chemical bonding is an attractive strategy that is advantageous over physical storage methods in terms of technical and safety characteristics. In this regard, various metal–hydrogen complexes (such as LiBH 4 and NaAlH 4 ), metal hydrides (such as NaH and MgH 2 ), and chemical compounds (such as NH 3 , CH 3 OH, and HCOOH) are widely employed in chemical hydrogen storage systems. − In particular, a liquid organic hydrogen carrier (LOHC) concept comprising liquid-state organic molecules has attracted considerable research attention owing to the high gravimetric hydrogen storage capacities of 5–8 wt %, reversibility of hydrogen charging and discharging, safe storage without energy losses, and transportation over long-distances using existing energy transport logistics. In addition, the LOHC materials have a great potential to meet the system-based vehicle applications goals set by the U.S. Department of Energy (5.5 wt %, 40 g L –1 hydrogen storage capacity) and European Union (5 wt %, 23 g L –1 hydrogen storage capacity). − …”

A new homocyclic methylbenzyl naphthalene (MBN) compound has been developed as a novel liquid organic hydrogen carrier (LOHC) medium with a high gravimetric hydrogen storage capacity of 6.44 wt % and good dehydrogenation ability. According to the results of theoretical calculations of designed MBN, MBN media possesses one of the lowest dehydrogenation enthalpies (<56 kJ mol H2 −1) among homocyclic LOHC media. The Friedel−Craft alkylation reaction allows the formation of an MBN regioisomeric mixture, which minimizes the production cost for practical applications. This mixture exists as a liquid with a high boiling point (>623 K) at ambient temperature. The H 2 storage efficiency of MBN was optimized to achieve a yield of greater than 99% using a new Ru-based catalyst. The reaction monitoring study suggests the stepwise hydrogenation reaction of aromatic rings, which allows the proposed hydrogenation mechanism. The extraction of H 2 from hydrogen-rich H 16− MBN was conducted via a dehydrogenation reaction (yield > 99%) using a Pt/CeO 2 catalyst, which enabled fast H 2 release. The faster and facile dehydrogenation of MBN compared to the other reported homocyclic LOHC media coincides with the theoretical calculation results.
