The benefits of Underground Hydrogen Storage
Ardent Underground can deliver the critical missing link in the green hydrogen transition: safe, scalable, and affordable large scale storage.
Safe Storage
Hydrogen is stored in an environment absent of oxygen and any potential ignition source. The below-ground storage system eliminates the risk of impact to the tank.
Pure Hydrogen Storage
Storing compressed hydrogen deep underground, without affecting hydrogen purity.
Affordable
The surrounding rock takes on the duty of containing the hydrogen pressure – no need for costly pressure containment materials.
Large Scale
Hydrogen storage sizes of up to 150 tonnes per shaft. For larger storage, multiple shafts can be built in the same location.
Replicable
The shaft storage construction process can be reproduced in different locations with minimal design adjustment.
Small Footprint
The above ground footprint is very small compared to equivalent pressure vessel storage.
