MgH2–TiF4-MWCNTs based hydrogen storage tank with central tube heat exchanger

Mg–Ni–La based small hydrogen storage tank: kinetics, reversibility and reaction mechanisms

“…1(A) was packed with 44.7248 g of as-milled MgH 2 -Ni-La@TiF 4 -CNT. 37,38 Temperature proles during hydrogen exchange reaction were detected by K-type thermocouples (TCs, À250 to 1300 C, SL heater) placed along the tank length (TC1, TC3, and TC4) (Fig. 1(B)).…”

“…De/rehydrogenation were performed using a test station integrated with a controller program constructed by a LabVIEW® soware. [37][38][39] System pressures were measured by pressure transducers using an OMEGA Engineering PX409-1.5KGI and PX309-3KGI. Temperature and pressure signals detected during the experiments were collected using the module data loggers (NI USB-6009, National Instruments).…”

Hydrogen Storage Properties of Ball Milled MgH2 with Additives- Ni, V and Activated Carbons Obtained from Different By-Products

“…The MgH 2 -based hydrogen storage tanks with two types of additives such as NbF 5 or TiF 4 and activated carbon or MWCNTs demonstrated very good reversibility by maintaining their hydrogen absorption capacity upon cycling [19][20][21]. Although due to deficient heat management and hydrogen diffusion the sorption performance inside the tank was not homogeneous, these obstacles could be solved by designing and fabricating an appropriate tank equipped with a heat exchanger and gas diffusion pathways.…”
