Hydrogen may play a key role in future sustainable energy system as carrier of renewable to replace hydrocarbons. This review describes the fundamental physical and chemical properties hydrogen basic theories sorption reactions, followed by emphasis on state-of-the-art storage selected interstitial metallic hydrides magnesium hydride, especially for stationary related utilizations. Finally, new perspectives utilization metal other applications will be reviewed.
Metal hydrides are known as a potential efficient, low-risk option for high-density hydrogen storage since the late 1970s. In this paper, present status and future perspectives of use metal discussed. Since early 1990s, interstitial base materials Ni – hydride rechargeable batteries. For storage, systems have been developed in 2010s [1] emergency or backup power units, i. e. stationary applications. With development completion first submarines U212 A series by HDW (now Thyssen Krupp Marine...
Magnesium hydride owns the largest share of publications on solid materials for hydrogen storage. The “Magnesium group” international experts contributing to IEA Task 32 “Hydrogen Based Energy Storage” recently published two review papers presenting activities group focused magnesium based and Mg compounds energy This article not only overviews latest both fundamental aspects Mg-based hydrides their applications, but also presents a historic overview topic outlines projected future...
Since the 1970s, hydrogen has been considered as a possible energy carrier for storage of renewable energy. The main focus on addressing ultimate challenge: developing an environmentally friendly successor gasoline. This very ambitious goal not yet fully reached, discussed in this review, but range new lightweight hydrogen-containing materials discovered with fascinating properties. State-of-the-art and future perspectives solids will be discussed, metal borohydrides, which reveal...
Liquid hydrogen carriers are considered to be attractive storage options because of their ease integration into existing chemical transportation infrastructures when compared with liquid or compressed hydrogen. The development such forms part the work International Energy Agency Task 32: Hydrogen-Based Storage. Here, we report state-of-the-art for ammonia-based and organic carriers, a particular focus on challenge ensuring easily regenerable, high-density storage.
Hydrogen has a very diverse chemistry and reacts with most other elements to form compounds, which have fascinating structures, compositions properties. Complex metal hydrides are rapidly expanding class of materials, approaching multi-functionality, in particular within the energy storage field. This review illustrates that complex may store hydrogen solid state, act as novel battery both electrolytes electrode or solar heat more efficient manner compared traditional materials. Furthermore,...
A high-entropy alloy (HEA) of HfNbTiVZr was synthesized using an arc furnace followed by ball milling. The hydrogen absorption mechanism studied in situ X-ray diffraction at different temperatures and ex neutron experiments. body centered cubic (BCC) metal phase undergoes a transformation to tetragonal (BCT) hydride with occupying both tetrahedral octahedral interstitial sites the structure. Hydrogen cycling 500 °C is stable. large lattice strain HEA seems favorable for sites. HEAs therefore...
Abstract Hydrides based on magnesium and intermetallic compounds provide a viable solution to the challenge of energy storage from renewable sources, thanks their ability absorb desorb hydrogen in reversible way with proper tuning pressure temperature conditions. Therefore, they are expected play an important role clean transition deployment as efficient vector. This review, by experts Task 40 ‘Energy Storage Conversion Hydrogen’ Hydrogen Technology Collaboration Programme International...
Mix and match: A novel series of alkali-metal zinc borohydrides, LiZn2(BH4)5 (see picture), NaZn2(BH4)5, NaZn(BH4)3, with fascinating structures are presented. An interpenetrated network structure, containing a [Zn2(BH4)5]− ion, is observed for the first time borohydride. three-dimensional framework polymeric [{Zn(BH4)3}n]n− ion also identified.
Nanoparticles of magnesium hydride were embedded in nanoporous carbon aerogel scaffold materials order to explore the kinetic properties hydrogen uptake and release. A new modified procedure for synthesis nanoparticles is presented. The makes use monoliths (∼0.4 cm3) two distinct types resorcinol−formaldehyde aerogels loaded with dibutylmagnesium, MgBu2. Excess MgBu2 was removed mechanically, increase mass used as a measure amount MgH2. Energy-dispersive spectrometry revealed that MgH2...
X-ray reflectivity measurements reveal a significant dewetting of large hydrophobic paraffin surface floating on water. The phenomenon extends less than 15 \AA{} into the bulk water phase and results in an integrated density deficit about one molecule per $25--30\text{ }{\AA{}}^{2}$ contact with surface. are supported by molecular dynamics simulations related to effect.
Hydrogen is recognized as a potential, extremely interesting energy carrier system, which can facilitate efficient utilization of unevenly distributed renewable energy.

A highly porous form of Mg(BH4)2 (see picture; Mg green, BH4 blue, unit cells shown in red) reversibly absorbs H2, N2, and CH2Cl2. At high pressures, this material transforms into an interpenetrated framework that has 79 % higher density than the other polymorphs. can act as a coordination polymer many similarities to metal–organic frameworks.
