f FutureGrid Phase 1: Facility, Closure Report

The National Transmission System (NTS) is a cornerstone of the Great Britain’s (GB) energy infrastructure, transporting over 800 TWh of energy annually across 5,000 miles of pipelines in the UK.
This system provides GB with a significant opportunity to decarbonise various industries by transporting low-carbon gases such as hydrogen, biomethane and various synthetic fuels. Transitioning this system would also pave the way for industrial emitters to decarbonise either through fuel switching or transporting carbon dioxide to potential storage sites around the United Kingdom (UK). Recognising the imperative to transition to a low-carbon future, the FutureGrid project sought to explore the feasibility of repurposing the NTS to transport hydrogen. This project, an essential part of the National Gas HyNTS programme, endeavours to align the NTS with GB’s net zero ambitions by demonstrating the operational viability of the system with varying hydrogen blends using decommissioned assets, typical of the natural gas network today, ultimately aiming for 100% hydrogen conveyance.
This report was submitted to HSE for their assessment of the safety evidence for 100% hydrogen heating, which can be found at Hydrogen heating:HSE assessment of the safety evidence - GOV.UK.
