Hydrogen storage materials: four ways to hold H₂
A radial graphical abstract with a hydrogen molecule at the hub and the four ways to store it on the spokes: compressed gas, cryogenic liquid, physisorption in a metal–organic framework and chemical binding in magnesium hydride. A bottom strip shows how alloying, nanostructuring, nanoconfinement and catalysts tame magnesium hydride.

Step by step
- Compressed gasHigh-pressure tanks hold hydrogen as a gas but are dangerous (Sun et al. 2020)
- Cryogenic liquidLiquid hydrogen storage is costly (Sun et al. 2020)
- Physisorption in a MOFMOF-5, Zn4O(BDC)3, adsorbs 4.5 wt% at 78 K and 1.0 wt% at room temperature and 20 bar, binding H2 at zinc and at the linker (Rosi et al. 2003)
- Metal hydrideMgH2 stores 7.6 wt% (110 g/L) reversibly, but ΔH = 76 kJ/mol and Ea = 160 kJ/mol make release hot and slow (Sun et al. 2020)
- Taming MgH2Alloying, nanostructuring, nanoconfinement and transition-metal catalysts; nano-Ni moved the desorption peak from 370 °C to 260 °C (Sun et al. 2020); clusters below 2 nm change the thermodynamics (Cheng et al. 2012)

Questions
What does the “Hydrogen storage materials: four ways to hold H₂” template show?
A radial graphical abstract with a hydrogen molecule at the hub and the four ways to store it on the spokes: compressed gas, cryogenic liquid, physisorption in a metal–organic framework and chemical binding in magnesium hydride. A bottom strip shows how alloying, nanostructuring, nanoconfinement and catalysts tame magnesium hydride.
What are the steps shown in “Hydrogen storage materials: four ways to hold H₂”?
1. Compressed gas: High-pressure tanks hold hydrogen as a gas but are dangerous (Sun et al. 2020). 2. Cryogenic liquid: Liquid hydrogen storage is costly (Sun et al. 2020). 3. Physisorption in a MOF: MOF-5, Zn4O(BDC)3, adsorbs 4.5 wt% at 78 K and 1.0 wt% at room temperature and 20 bar, binding H2 at zinc and at the linker (Rosi et al. 2003). 4. Metal hydride: MgH2 stores 7.6 wt% (110 g/L) reversibly, but ΔH = 76 kJ/mol and Ea = 160 kJ/mol make release hot and slow (Sun et al. 2020). 5. Taming MgH2: Alloying, nanostructuring, nanoconfinement and transition-metal catalysts; nano-Ni moved the desorption peak from 370 °C to 260 °C (Sun et al. 2020); clusters below 2 nm change the thermodynamics (Cheng et al. 2012).
What are the starting materials and the product?
Starting materials: Hydrogen gas: light, abundant, burns to water. Product: Hydrogen held as a gas, a liquid, on a porous framework or inside a metal hydride.
