SGN unveil plans for world first 100% green hydrogen network

SGN has set out its plans for the world’s first green hydrogen to homes network, if given the green light by Ofgem.

On 18 May, it explained that its H100 Fife project, part of the Gas Goes Green initiative, would involve 300 homes in Levenmouth and demonstrate every aspect of an end-to-end hydrogen-to-homes system, supporting plans for large scale rollout in future. Having passed the initial screening submission process for Ofgem’s Network Innovation Competition, SGN will submit a full bid for funding in the summer. If successful, construction will begin in late 2020 or early 2021, with estimated completion coming within two to three years.

The 100% zero carbon hydrogen network would produce hydrogen through electrolysis from an Offshore Renewable Energy Catapult offshore wind turbine, with the proposed hydrogen production and storage system and heating network running alongside the current natural gas system. The on-site storage unit will hold enough hydrogen to ensure supply is not disrupted, even during the coldest weather conditions. The network would run for an initial five years from 2022/2023 with customers able to participate on an opt-in basis.

Angus McIntosh, Director of Energy Futures at SGN, said: “Hydrogen is an exciting energy vector that at scale could provide similar levels of safe, secure, reliable and affordable energy to what we enjoy now, with minimal disruption for customers. The project will provide key national evidence for hydrogen’s role in the UK’s energy transition and critical insight into the customer value proposition of hydrogen for heat.”
