What this tile covers Hydrogen held as compressed gas, liquid, in salt caverns, depleted gas fields or metal hydrides.

#### Key facts

| **Duration** | Days to seasons |
|---|---|
| **Chain** | Electrical → electrolysis → stored H2 → fuel cell or turbine → electrical |

#### Included from the reference tables

- Compressed and liquid hydrogen
- Salt caverns and depleted gas fields
