This project involved identifying a suitable site for field trials which would provide further vital evidence for a hydrogen conversion and corroborate the results of testing completed in the controlled environment.

A suitable site, such as one which had been demolished or was derelict, needed to be found on the NGN network. It was vital that the distribution network was still intact but could be disconnected from the live network to ensure the testing wouldn’t  interfere with the supply of gas to customers. The site needed to create a ‘real-life’ environment for 100% hydrogen field trials which could allow critical pieces of safety evidence gathered in Phases 1a and 1b to be verified.



This project included putting in place legal agreements with the council/land owner to undertake the trials, safety assessments for the site and developing the master testing plan. In addition, the project included a detailed design for the one Kilometre distribution network (MircoGrid), to be used for remote testing at DNV’s Spadeadam site.

This project was undertaken with a Network Innovation Allowance, and was being carried out at the same time as the NIC. The project identified a suitable site, owned by Redcar and Cleveland Council in the South Bank area of Middlesbrough.
