SGN’s strategic ambition towards Net Zero includes a network innovation, ‘proof of concept’, project; H100 Fife. This project will see SGN injecting 100% hydrogen into a new, purpose-built network which will be located in parallel to the existing natural gas network. The H100 Fife Project is considered of national and strategic importance to demonstrating a capability to meet the UK Net Zero target ambition. 


SGN’s current plan anticipates H100 customers will commence offtaking hydrogen in Q2 2023.      


Xoserve is to collaborate with SGN to assess the UK-Link systems and process impacts and, develop high-level solution options.
