Natural gas, which is mainly methane, is not green and will need to be phased-out or replaced with a green alternative. Historically, town gas had significant quantities of hydrogen, around 60% so we know that hydrogen can meet our household needs if the distribution system is configured appropriately. Work is now underway by Keele University to confirm that up to 20% of the gas for our homes could become hydrogen without changing our current gas fittings.
The supply of green hydrogen from NI Water sites could help the gas network to signal how it might migrate and remain relevant in a decarbonising world. We are assessing how many of our sites are adjacent to the gas network.
