On the dehydrogenation of LiAlH4 enhanced by Ti salts and cryogenic ball-milling

Biohydrogen production from fermentation of organic waste, storage and applications

“…(HES) offer the best option for energy capacity storage so that energy stored could vary in the large scale from 1 GWh to 1 TWh, while batteries typically range from 10 kWh to 10 MWh, and compressed air storage and pumped hydro range from 10 MWh to 10 GWh. The degree to which HES can penetrate energy storage markets will depend on multiple factors, including non-technological barriers such as policy, safety, and economic issues (Tena-García et al, 2020). In residential applications, hydrogen could be blended into existing natural gas networks at low concentration to overcome heat and cooking demand in buildings.…”

Improved dehydrogenation performance of LiAlH4 doped with BaMnO3

“…The absorption of LiAlH 4 is possible under ultra-high pressure [ 23 , 24 ]. Numerous attempts have been put forward to promote the kinetics and boost the hydrogen desorption of LiAlH 4 including adding additives/catalysts and a milling process [ [25] , [26] , [27] , [28] , [29] ]. In addition, Zhang and co-workers [ 30 ] exposed that some additives could exhibited unique morphology which may affected the hydrogen storage performance of LiAlH 4 .…”

Study of milling time impact on hydrogen desorption from LiAlH4-Fe2O3 composites

“…Various additives like pure metals [6][7][8], carbides [9,10], halides [11][12][13][14][15], carbon based materials [16], metallic oxides and oxide ceramics [17][18][19][20][21][22][23][24] and hydrides [12,25] were used in order to improve the hydrogen sorption properties of LiAlH 4 . These improvements are achieved due to the reduction of the particle size of hydrides to the nanoscale, an increase in reactive particle surface area, destabilization of the hydride crystal structure and catalytic performance of additives.…”

“…During the milling process, the temperature in the milling chamber can significantly increase, reaching the temperature of R1 or even R2 leading to the degradation of hydride and the decrease in the hydrogen storage capacity of the material. Prevention of the hydride decomposition during the preparation was done in cryogenic ball-milling [12,13]. But this process requires the liquid nitrogen temperature.…”
