Interactive map (under review)

This map shows an overview of the proposals we presented at our second, statutory consultation – the area where our pipeline will be routed and temporary construction areas located, as well as potential Hydrogen Above Ground Installation (HAGI) and Block Valve Installation (BVI) locations.

See map

HAGIs

The majority of our pipeline will be underground. However, we will need around 10 HAGIs at certain points along the pipeline. This includes a Central Hub HAGI, which will act as the central connection point for each of our four pipeline route corridors.
