UK study to explore oxygen dosing and alternatives for hydrogen pipelines | Hydrogen
Engineering consultancy Penspen will assess the use of oxygen as a potential solution to prevent hydrogen embrittlement as the UK builds out a national hydrogen pipeline network. The project has been awarded by National Gas Transmission and is being funded through UK energy regulator Ofgem’s Network Innovation Allowance. Hydrogen is known to cause steel pipelines to become more brittle by reducing their structural integrity. It poses a challenge for both new hydrogen infrastructure and the repurposing of existing gas assets. Oxygen added in small, controlled amounts can inhibit embrittlement by absorbing onto the steel’s surface and blocking hydrogen from entering the metal. The findings could play a key role in future pipeline projects. National Gas Transmission is developing a proposed 1,500-mile hydrogen transmission system to support energy security and the decarbonisation of hard-to-abate industrial sectors.… Read More »UK study to explore oxygen dosing and alternatives for hydrogen pipelines | Hydrogen
