Insights on hydrogen spillover on carbonaceous supports

“…1,2 In particular, solid state hydrogenation is essential for hydrogen scavenging [3][4][5] from systems in which the accumulation of gaseous H 2 is unwanted, such as in nuclear waste storage (as the result of a radiolytic H 2 formation), [4][5][6][7][8][9][10][11][12] for use of H 2 as a reagent 13,14 or as a fuel, 15,16 and for the safe H 2 storage and transportation. [15][16][17][18][19] The present study demonstrates the solvent-free solid-state hydrogenation of acetylenes using 1,4-bis( phenyl-ethynyl) benzene (PEB) as a hydrogen acceptor. The compound PEB has nine hydrogenation products, as presented in Fig.…”

A review on BCC-structured high-entropy alloys for hydrogen storage

“…In promising alloy systems, rare earth-based alloys show excellent potential as they possess favourable room temperature reversible hydrogen absorption/desorption properties and long-term cycling stability (Dashbabu et al, 2022;Lv et al, 2022), but are more restricted to Ni-MH battery applications due to their low hydrogen storage capacity (Liu et al, 2004). Constrained by the difficulty of activation and sensitivity to impurities, TiFe-based alloys are only the candidates for hydrogen compressor and vehicle applications, despite their low price and fairly low hydrogenation temperature (Peng et al, 2021;Li et al, 2022;Liu et al, 2022a;Zhang et al, 2022). The unique advantages of Mg-based alloys in terms of a high hydrogen storage capacity make them a strong contender for vehicle-mounted hydrogen storage materials.…”

Mathematical modelling and design of the ionic liquid compressor for the hydrogen refuelling station

“…As one of the application fields of hydrogen energy, the hydrogen fuel cell vehicle (HFCV) plays a vital role in reducing greenhouse gases, especially in the field of trains, ships, long‐haul trucks, and buses 7 . The second Mirai HFCV equipped with three 70 MPa hydrogen storage tanks was launched by Toyota in 2020, which can achieve over 700 km driving distance 8 . However, this transition from the conventional energy source into fossil‐free energy is undergoing a slow process due to the challenge in the generalization of hydrogen energy as the lowest volumetric energy density exhibited in hydrogen among the commonly used fuels 9 .…”

“…7 The second Mirai HFCV equipped with three 70 MPa hydrogen storage tanks was launched by Toyota in 2020, which can achieve over 700 km driving distance. 8 However, this transition from the conventional energy source into fossil-free energy is undergoing a slow process due to the challenge in the generalization of hydrogen energy as the lowest volumetric energy density exhibited in hydrogen among the commonly used fuels. 9 The technologies for increasing the volumetric energy density are then critical for the advancement of hydrogen energy especially the construction of hydrogen refuelling stations for the HFCVs.…”
