Radius Systems has been testing procedure to stop gas flow for gas operations under 100% hydrogen conditions


Testing underway at H21 Phase 2b site

Phase 2b of our H21 project is now live, with testing underway on a network of existing natural gas mains in the South bank area of Middlesbrough. This is an exciting ‘world-first’ project as it is believed to be first time standard gas operational procedures have been tested under 100% hydrogen conditions on an existing network.

The gas pipes once supplied 70 homes on the site and are disconnected from the rest of the network.

The evidence gathered will be used to understand any changes needed for the potential conversion of the gas distribution network to transport hydrogen in the future. The project follows earlier H21 projects including the testing of operational procedures on a purpose built MicroGrid at Spadeadam (Phase 2a).

To celebrate the start of testing Porject Manager Neil Travers, along with Tim Harwood and Russ Oxley welcomed local Mayor Ben Houchen, MP Jacob Young and council leader Mary Lanigan to the site to see the testing for themslelves. This was reported across media including BBC Look North – watch here.

And you can see what our stakeholders had to say about the project here.

In addition to testing network procedures, the project includes the installation of two domestic hydrogen boilers. Produced by leading manufacturers, Vaillant and Baxi the boilers have been connected to the network, and use hydrogen, which has been odourised to smell the same as natural gas in another ‘world-first’.
