In order to stimulate growth in the hydrogen economy, SGN have developed the Aberdeen Vision and NE Industrial Clusters projects. These projects involve the installation of a dedicated hydrogen pipeline from St Fergus to Aberdeen. The outputs of this study are to produce a Pre-FEED analysis that will provide a clear basis for FEED execution. Illustrating preferred development of pipeline routeing, required pipeline facilities, ensuring its characteristics will support further expansion of the hydrogen system and detailed costs for FEED will be critical to ensure SGN secure funding under Ofgem’s Net Zero Pre-Construction and Net Zero Reopener funding mechanisms.

Learnings
Outcomes
Transmission Assets Analysis
Phase 1 has been completed and shows there is a viable route between St Fergus and Aberdeen City for the Hydrogen transmission
pipeline. All the tasks in phase one have been completed and reported on and these are now in the process of being updated as part
of phase 2, the outcomes of which will be identified upon conclusion of the pre-FEED.
Below 7 bar analysis
Phase 1 of the below 7 bar analysis which includes a comprehensive Terms of references with all the assumptions has been
completed and the project is now progressing to phase 2.
Lessons Learnt
Transmission Assets Analysis
As discussed above in Section 4, the key lesson learned from the Phase 1 scope of work is to improve the initial identification of
suitable pipeline route corridors and routing constraints in a timely manner as the routing is a key input to other engineering activities
such as flow assurance, pipeline mechanical design and identification of crossings. It is also imperative to get early engagement with
construction to get their insight and opinion of the proposed routing corridor(s) and construction methods at crossings which could
have an impact on the selected route.
Whilst the route planning during this project took much longer than expected due to additional modifications required to the AI software
for gas pipelines, a final report by Continuum Industries outlines the benefits of the tool for future projects that will deliver savings in cost
and time when applying the software to other projects involved in route planning.

previous Project Progress information was reported.
