Research says traditional hydrogen blending could damage gas pipelines

University College London researchers have said in a new study that the pumping of hydrogen into gas networks poses risks and requires a rethinking of usual blending techniques.

The low molecular mass of hydrogen reduces the penetration of a side-branch flow and increases the buoyancy forces leading to stratification with high hydrogen concentrations on the upper pipe surface, downstream of the branch, the team said.
