Hydrogen is an energy medium which can be stored, transported and converted. However, a key challenge to the full development of hydrogen based technologies is storing hydrogen safely, efficiently and economically. When stored in the solid state, it offers clear advantages over storage in liquefied form.

The encouraging hydrogen storage material is carbon nanotubes since their synthesis [27]. Some previous research works denoted that carbon nanotubes have superior storage of hydrogen molecules, however later works proved otherwise [28–33]. In pure carbon nanotubes, below 1 wt.% of hydrogen can be adsorbed [34–36].

How Hydrogen Storage Works. Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is − ...
