In order to utilise the existing distribution gas network to transport hydrogen, the effects of the changes in characteristics of hydrogen from natural gas need to be reviewed and the effect on the network assessed. This is particularly of importance for the H21 Phase 3 Occupied Trials project and future conversion projects.
The velocity, density and viscosity of hydrogen through the gas distribution network will be different to natural gas. These changes may have an adverse effect on the network and so the impacts need to be reviewed. The project will involve engaging with experts to undertake a research review and assessment of the known characteristic changes of hydrogen vs methane and how that will affect the transportation of hydrogen through the existing gas network.
