Metal hydride materials. Over the past 30 years several hydrogen storage systems based on reversible metal hydrides have been evaluated for vehicle applications [5]. Most of these have involved either pure metals (like Mg) or, more commonly, intermetallic alloys (like LaNi 5, TiCrMn, and FeTi) as metal hydrides.

The WTT efficiency is 43.6–43.9% for the liquid hydrogen option, 21.0% for the SBH option, and 18.9% for the MgH 2 slurry option. The differences in WTT efficiencies for the different options are mostly due to the varying amounts of energy consumed in storing/regenerating hydrogen. Download : Download full-size image.

Since hydrogen is flammable, explosive and a lighter gas than air, hydrogen storage, delivery and safety system are directly related to each other [1], [5], [18], [19]. The minimum ignition energy of hydrogen is 0.02 mJ, it is more sensitive to fire [74].

3.4.4.1 Hydrogen storage. Hydrogen energy storage is the process of production, storage, and re-electrification of hydrogen gas. Hydrogen is usually produced by electrolysis and can be stored in underground caverns, tanks, and gas pipelines. Hydrogen can be stored in the form of pressurized gas, liquefied hydrogen in cryogenic tanks, metal

Net reaction (the redox): (6) 2 H 2 + O 2 = 2 H 2 O + Electricity + Heat. Hydrogen''s lower energy density than other fuels makes on-board storage a major obstacle for use as a vehicle fuel. The work becomes harder due to the need of high pressures for storage due to the low density of hydrogen.

Hydrogen storage is a key enabling technology for the extensive use of hydrogen as energy carrier. This is particularly true in the widespread introduction of

Battery electric vehicles are making headlines, but fuel cells are gaining momentum—with good reason. Hydrogen could play a vital role in the renewable-energy system and in future mobility. At the COP21 meeting in Paris in 2015, 195 countries agreed to keep global warming below 2 degrees Celsius above preindustrial levels.

The concept consists of storing hydrogen in a pressure vessel that can operate at cryogenic temperatures (as low as 20 K) and high pressures (e.g. ∼350 atm). This vessel can be fueled with LH 2, compressed gaseous H 2 (e.g. 350 atm CGH 2) or with cryogenic hydrogen at elevated supercritical pressures, namely cryo-compressed

HYDROGEN STORAGE MODES As has been mentioned earlier, onboard storage has often been found to be a serious obstacle to realisation of a practical hydrogen-fuelled automobile.
