“…The utilization of renewable and clean energy is an urgent task of recent research . Hydrogen has long been considered as a clean and efficient energy carrier due to its abundance, environmental friendliness, high energy density, and recyclability. − However, one of the bottlenecks and challenges in the implementation of hydrogen energy is the lack of efficient hydrogen storage method. , Tremendous research efforts have been made in the past half-century on hydrogen storage, including physical (such as compression, liquefaction, and physisorption − ) and chemical methods (such as metal hydrides, , complex hydrides, − chemical hydrides, − and liquid organic hydrogen carriers (LOHCs) − ). To uptake and release a large amount of hydrogen reversibly under mild conditions, two criteria are to be met, i.e., high hydrogen capacity (≥5.0 wt %) and suitable thermodynamic properties (the heat of hydrogen desorption (Δ H d ) is around 30 kJ/mol-H 2 ).…”

Materials for hydrogen storage have been extensively explored for a few decades. Thousands of materials have been synthesized and tested; however, few systems could meet the practical requirements. Metalorganic hydrides discovered recently offer new opportunities. It is, however, extremely time-consuming and inefficient to experimentally screen potential materials from a large variety of metal cations and organic anions. In the present study, we performed wide-ranging theoretical predictions and screened more than 90 metalorganic hydrides; 20 of them were identified with both high hydrogen capacities (≥5 wt %) and suitable thermodynamics (heat of H2 desorption: 25–35 kJ/mol-H2) that allow hydrogen uptake and release near ambient condition. We picked up four of them, i.e., Li/Na indolides and 7-azaindolides, for experimental validation. All the four candidates can be easily synthesized via the reactions between the metal hydrides and the corresponding organic precursors. Among them the structures of lithium indolide (P21/c (no. 14)) and sodium 7-azaindolide (P4̅21 c (no. 114) were successfully resolved. Photoelectron spectroscopy and quantum chemical calculations confirmed that the charge density of the organic ring increased with the introduction of an alkali metal, thus optimizing their ΔH d for hydrogen storage. Importantly, we demonstrated experimentally that lithium indolide with a theoretical hydrogen capacity of 6.1 wt % has a heat of hydrogen absorption of ca. 33.7 kJ/mol-H2 which is in excellent agreement with the value (33.6 kJ/mol-H2) predicted theoretically. The partially reversible hydrogen release and uptake can be can be achieved at the temperature as low as 100 °C. These results illustrate the great potential of metalorganic hydrides for tackling the grand challenge of hydrogen storage and manifest the effectiveness of theoretical prediction in guiding materials fabrication.

“…Next to this major technology, liquefied hydrogen has been established to a much smaller extent. A major advantage over compressed hydrogen is that the density is much higher . Since hydrogen has the second lowest critical temperature of all substances (33.19 K = −239.96 °C; only helium has a lower one), very low temperatures are required.…”

Storage of hydrogen in an efficient and dense manner is still a challenge. In addition to the conventional technologies of compression and liquefaction, there are different approaches trying to enhance the storage density by bonding hydrogen to another substance. Physisorption and chemisorption to organic as well as inorganic carriers are options. Although many of these technologies have not yet gone beyond the technological readiness of lab scale tests, there are a few that have already reached advanced technological levels. The first part of this two‐part review discusses storage technics with recovery of elemental hydrogen.

“…A large amount of work has been done in developing hydrogen for use in transportation (Swain & Adt, 1973;MacCarley & Vorst, 1979;Peschka & Carpetis, 1979;Wolley, 1979;Podgorny & Mischenko, 1981;Biichner, 1982;Furuhama & Kobayashi, 1982). Several hydrogen-driven cars and buses are in existence.…”

Our Biosphere, the only one known to exist, is under attack by various factors. Major culprits amongst these include fossil-fuel-produced air pollution, acidic precipitation (acid rains), and CO2. As we run out of petroleum and natural gas, the question becomes: what should the new energy-system be, so that the damage to The Biosphere and life can be stopped? In view of the rapid depletion of the main energy sources of the present, the fluid fossil-fuels, this paper analyses the various primary energy-options (such as coal, breeder reactors, fusion reactors, and solar energy), and also considers such possible energy-carriers as synthetic fossil-fuels and hydrogen. In this analysis, the environmental effects of various options are considered both qualitatively and quantitatively.It is concluded that the Hydrogen Energy-system is the most efficient and economical energy-system possible, and that it results in the environmentally most compatible and permanent energy-system when coupled with solar energy as the primary energy-source. It is important now that this information be disseminated among the public in general, and environmentalists in particular, so that the implementation of the solar-hydrogen economy can be started without delay, in order to minimize any further damage to The Biosphere and its living components.
