H21 Projects

This NIA project is focused on reviewing and assessing the existing Northern Gas Networks Gas Safety Case to enable NGN/H21 to undertake 100% Hydrogen Village Trials

This NIA project is focused on preparing and enabling work for the first occupied 100% hydrogen trials which will form Phase 3 of H21.

This NIA project is focused on exploring the effects of delivering hydrogen on the distribution network and planning mitigations and developing solutions to aid conversion from natural gas to hydrogen.

This NIA project is focused on reviewing the service connections from the distribution pipework to the ECV, including modelling the hydrogen demand for various pipe diameters and lengths.

This NIA project is focused on collating industrial and commercial data for NGN and Cadent networks to identify and understand mitigations required to convert industrial and commercial customers from natural gas to hydrogen.

Now a £10.3 million collaborative gas industry programme, the H21 NIC work will deliver the quantified safety evidence necessary to inform a government policy decision on hydrogen for use in the existing gas network.

Once funding is secured, this will involve essential field trials on a decommissioned part of the NGN network, in order to provide the critical pieces of evidence supporting the knowledge from Phases 1a and 1b. Testing will deliver the evidence required to progress to live trials.

Public perceptions of hydrogen are currently only guessed at by the research and industry community. As a result, we have no idea about how communities and individuals would respond to the prospect of a 100% hydrogen conversion, which could change the look and feel of daily core practices e.g. cooking and heating.

Developed in partnership with global energy giant Equinor and UK gas distributer Cadent, this project builds on the original Leeds City Gate, presenting a conceptual design for converting the North of England to hydrogen between 2028 and 2035.

This project seeks to extend the principle of hydrogen conversion as established in the Leeds City Gate, across key UK urban centres.

The primary focus of this project was to understand what was required at the NIC Phase 1a and 1b test sites. It also ensured the designs had a level of independent assurance, providing confidence in effective test execution.

This project will determine the suitability of existing domestic and commercial meters for operation on a hydrogen network.

Using England’s fourth largest city as a blueprint, this pioneering feasibility study, led by Northern Gas Networks, confirmed that conversion of the UK gas network to 100% hydrogen was both technically possible and could be delivered at a realistic cost.
