What's Happening?
Penspen, a UK-based engineering consultancy, and National Gas Transmission have launched a study focused on preventing hydrogen embrittlement in steel pipelines. This initiative is crucial as the UK aims to transition to zero-emission technologies by
repurposing over 6,000 kilometers of natural gas pipelines for hydrogen use. Hydrogen embrittlement occurs when atomic hydrogen infiltrates steel, compromising its strength and safety. The study will explore the use of impurity gases, such as trace oxygen, to inhibit atomic hydrogen and maintain pipeline integrity. This collaboration aims to ensure the safe and efficient transition to a low-carbon future by addressing the challenges posed by hydrogen embrittlement.
Why It's Important?
The study's significance lies in its potential to facilitate the UK's energy transition by enabling the use of existing natural gas infrastructure for hydrogen transport. Building new hydrogen pipelines would be costly and time-consuming, whereas retrofitting existing pipelines with gas inhibitors could allow for immediate hydrogen blending, reducing CO2 emissions and accelerating the adoption of green hydrogen in various sectors. This approach not only offers a cost-effective solution but also leverages existing expertise in pipeline management, making it a practical step towards achieving the UK's net-zero targets.
What's Next?
As the study progresses, Penspen and National Gas Transmission plan to develop a best-practice guide for gas inhibition, detailing optimal inhibitor mixes and monitoring strategies. This guide will serve as a blueprint for operators looking to implement zero-emission technologies across their networks. The study's findings could lead to regulatory changes, allowing for higher oxygen levels in gas streams, and necessitate the deployment of advanced sensor arrays for monitoring. Successful implementation could significantly reduce capital expenditures and greenhouse gas emissions, positioning the UK as a leader in sustainable energy solutions.
Beyond the Headlines
The study addresses a critical challenge in the hydrogen economy: the vulnerability of pipeline steels to hydrogen embrittlement. By focusing on inhibitor gases, the research could transform theoretical insights into practical solutions, ensuring the longevity and safety of hydrogen infrastructure. This initiative not only supports the UK's decarbonization goals but also sets a precedent for other countries looking to transition to hydrogen energy. The collaboration highlights the importance of integrating existing knowledge with innovative approaches to overcome technical barriers in the pursuit of a sustainable energy future.
