Current situation and prospect of hydrogen storage technology with new organic liquid

Catalytic hydrogenation and dehydrogenation of N-ethylindole as a new heteroaromatic liquid organic hydrogen carrier

“…Safe and efficient utilization of hydrogen power provides a convenient way to help combat the pressing challenge of global greenhouse gas emissions [1,2]. Central to the potential mass deployment of hydrogen technologies in the market place is the development of large scale, high density and safe storage and transport of hydrogen, which unfortunately has remained to be one of the grand challenges for the incipient hydrogen economy today [3e5].…”

Hydrogenation Kinetics of N‐Ethylindole on a Supported Ru Catalyst

“…Hydrogen is stored via catalytic hydrogenation in a hydrogenation factory off‐board, transported to a stationary filling station, and released on‐demand via catalytic dehydrogenation under well‐controlled conditions onboard. It has been proved this process can be fully reversible . Upon hydrogenation, the carrier compounds become liquid under ambient conditions .…”

“…It is, however, difficult to store hydrogen and to transport it safely in commercial quantities without using bulky, heavy‐duty equipment, either through compression or cryogenic liquefaction, because of its low boiling point and high flammability. Thus, commercially viable hydrogen storage technologies have become one of the roadblocks to the developing ways to use hydrogen energy on a large‐scale …”

“…The vehicle tank is divided into two parts via a movable separator: one for hydrogenated LOHCs and the other for dehydrogenated LOHCs. The storage method based on LOHCs provides a starting point for developing very safe and practical technology for large‐scale hydrogen storage and delivery, especially for use in mobile and vehicular applications . N ‐ethylcarbazole (NECZ) was firstly found to enable dehydrogenation under 200 °C .…”

A new lanthanum(III) complex, [La(MO)3(DMF)3(H2O)2] (MO = methyl orange), and La2O2SO4 nanoparticles; electrocatalytic activity for adsorption/desorption/evolution of hydrogen

“…Hydrogen is one of the most promising energetic materials, free-pollutant element and an important raw material for many industrial presses which can be widely used as one of the fuel as it exhibits the highest heating value per mass of all the chemical fuels, so called "clean and green" energy [1][2][3][4][5][6][7][8][9][10][11][12][13]. Since shortcoming energy and pollution of environment become a global concern, there is an effective to produce clean fuels and replace fossil fuels, this has led to the development of new materials, which are able to absorb as well as desorb large quantities of hydrogen by forming compounds, such as hydrides (H -), thus have been extensively studied for decades.…”
