Webinar - Materials & Hydrogen – Delivering Project Union
The United Kingdom has set an ambitious target of eliminating net carbon emissions by 2050 and a wide range of green technologies are required to reach this goal. One key technology is hydrogen as an alternative for carbon fuels in heat, transport, and industry. National Gas Transmission Plc, as the owner and operator of the National Transmission System (NTS) in Great Britain, is supporting the transition to hydrogen via the creation of a 100% hydrogen backbone, known as Project Union, linking industrial producers and users throughout the country via a largely repurposed network of high-pressure pipelines. However, the NTS was not designed to transport hydrogen, and as such, a programme of work has been developed to understand and manage the impact of hydrogen on the pipeline assets.
The approach to repurposing the NTS will be discussed in the context of key projects undertaken at National Gas Transmission to understand and assess the capability of the network to transport high-pressure hydrogen. A summary of the extensive materials test programme and detailed characterisation work on ex-service and new pipeline steels will be presented alongside a review of technologies considered to mitigate the detrimental effects of hydrogen on metals.
