Underground Hydrogen Storage | Leasing
The proposed site in Dorset lies above the thickest onshore section of the Dorset Triassic salt deposit, aiming to provide approximately 6.5-10 TWh of hydrogen storage annually. This capacity, claimed to represent around 10-20% of the UK’s estimated hydrogen storage demand by 2050, appears promising on paper. However, it is essential to consider whether this location is truly optimal for long-term strategic objectives.
The facility’s proximity to SGN’s planned H2 Connect hydrogen pipeline is certainly advantageous, potentially enabling seamless integration into the Solent Cluster and the broader southern UK hydrogen supercluster. Yet, the success of this strategy hinges on the timely completion and operational efficiency of the H2 Connect pipeline. Delays or technical issues with the pipeline could undermine the storage facility’s utility, making the location less of an asset and more of a liability.
