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 − ...

In contrast, in the PVT component, a portion of the solar radiation absorbed by the cells is converted into electrical energy, while the remaining energy can be absorbed by PCM and HTF. Furthermore, the air gap shown in Fig. 2 contributes to a higher melting fraction of PCM in the STE component, by reducing the heat transfer to the environment.
