H21 is a suite of gas industry projects, carrying out vital work to prove that the gas network can safely transport hydrogen in the future.
Over a third of the UK’s carbon emissions are generated by the 83% of domestic homes currently using natural gas for heating and cooking. The UK is committed to reaching net zero emissions by 2050, so the gas we use needs to change. Hydrogen can play a vital role because it produces no carbon at the point of use.
Reusing the existing gas network to transport hydrogen could lead to the least disruptive and most cost effective route to carbon free heating for the majority of homes. It would also make use of a vast asset with the ability to deliver a reliable and flexible supply of gas.
Boris Johnson’s 10 point plan included a commitment to hydrogen production with the aim of heating a neighbourhood with hydrogen gas by 2023 and then an entire town, with tens of thousands of homes, by the end of the decade. The Climate Change Committees’ sixth carbon budget and the government’s Energy White Paper also both committed to a role for hydrogen to tackle decarbonisation and create jobs in an emerging green economy.
The H21 programme is funded by Ofgem and led by Northern Gas Networks in partnership with Cadent Gas, West and West Utilities, SGN, National Grid, Leeds Beckett University, DNV and the Health and Safety Executive. This means the work is undertaken on behalf of the gas networks so there is no duplication of effort and the projects bring together the very best expertise. H21’s first project examined the gas network in Leeds and produced the Leeds City Gate feasibility study. The report concluded it was technically possible and economically viable to decarbonise the UK’s gas distribution networks by converting them from natural gas to 100% hydrogen at an acceptable cost to the customer.
Since the Leeds City Gate report proved that a hydrogen gas conversion was technically possible and economically viable, the scope of H21 has expanded to include multiple projects which tackle the many different challenges of a hydrogen gas conversion.
Phase one of the work is now complete and phase two is underway. Current projects include testing hydrogen on a purpose built micro-grid, which represents a typical UK distribution network at Spadeadam. The microgrid, which is believed to be a world-first will be used to review, test and make recommendations to amend the operational and maintenance procedures required to operate a network on 100% hydrogen.
The project team will also shortly trial 100% hydrogen trials on a section of the gas network in the South Bank area of Middlesbrough which will be disconnected from the existing gas network for the trial period. Several months of rigorous testing of gas operations and maintenance activities will take place, practising what gas networks do every day but in a hydrogen world.
