Hydrogen / Power-to-X

The Local Transmission System (LTS) is the backbone of the United Kingdom (UK) energy network, delivering natural gas from the National Transmission System (NTS) to towns and cities across the country. The four Gas Distribution Networks (GDNs) operate approximately 11,000 km of high-pressure pipelines, operating at pressures above 7 barg. The...

This article describes an approach to the assessment of steel pipelines regarding their potential suitability for hydrogen transportation. The assessment is made based on pipeline inventory data available in georeferenced form in a GIS, as well as in supplementary databases, and uses the software platform trascue. PIMS by GEOMAGIC GmbH, combined...

Carbon capture and storage (CCS) plays a critical role in meeting global net-zero targets. Pipeline clusters are under development to transport carbon dioxide (CO2) from disparate emitters to a common injection site. Design requirements vary depending on system configuration and transport phase (gas versus dense). Examples are: Diverse industries...

Welcome to the 2nd issue of the Pipeline Technology Journal in 2024 which is addressing aspects of the climate emergency and the role the pipeline industry can play. As an integral part of the advancing global energy transition, it is expected to supply cleaner, more sustainable yet affordable energy in the near future. An emphasis on decarbonizing...

PETRONAS is considering pipeline repurpose option for one of its CCS projects in Malaysia. One of the opportunities identified is to repurpose existing gas export pipelines, 24in and 30in with combined distance of 200km from offshore to onshore. Existing technical frameworks from available standard and internal resources for pipeline repurpose have...

At COP26 countries were asked to come forward with ambitious 2030 reduction targets that align with meeting net zero emissions by the middle of the century (UK COP). Governments have also agreed to keep global warming well below 2C and make efforts to keep it to 1.5C. Carbon capture and storage (CCS) is going to play an important role in...

Methane is the second most abundant anthropogenic greenhouse gas (GHG) after carbon dioxide: it is estimated1 that its concentration in the atmosphere is approximately 2.6x higher than the pre-industrial levels and this contributes for at least 25% of the global warming. As methane is the main component of natural gas, a strong reduction of its...

Vibroacoustic technology, developed by Eni, is a consolidated approach for pipeline monitoring applications. Today, e-vpms® is protecting about 1800 km of pipelines worldwide, with a commitment to constant technological evolution and continuous improvement. In this framework, the work presents some notable cases experienced over the monitored...

The climate emergency and energy security are some of the biggest challenges humanity must face in the 21st century. The advancing global energy transition faces many challenges when it comes to ensuring a sustainable, reliable and affordable energy supply. The energy industry is currently going through its biggest change in living memory, despite...

The Reliability Focused Analysis Technique is a method of analysis that can be used to evaluate reliability for a specific system, and addresses availability and maintainability related issues. This approach is based on holistic reliability and evaluation and analysis of maintenance data, which involves reviewing maintenance strategies, system...

Existing gas infrastructure plays an essential and important role in today’s energy transition for the transport and storage of Hydrogen. Studies show, natural gas infrastructure can be economically utilized for the transport and cavern storage of Hydrogen in future decarbonized energy systems. Repurposing existing pipelines and underground storage...

A number of CPW manufactured HFW and SAWL pipes were tested for fracture toughness properties in high pressure 100% hydrogen environment. All tests were performed in RINA laboratory, following a developed test procedure based on code ASME B31.12 Option B (qualification of the material threshold stress intensity factor KIH). Testing involved API 5L...

Hydrogen is expected to play a key role in the decarbonised future of energy. For hydrogen distribution, pipelines are seen the main method for mass transport of hydrogen gas. To support the evaluation of risk related to hydrogen pipelines, a revised QRA methodology is presented based on currently available and industry accepted guidance related to...

Increasing the use of renewable energy requires new ap proaches to energy storage and energy transp ort. One of these approaches is to st ore and transport hydrogen in natural gas pip eline networks. Blending hydrogen into the existing natural gas pipeline network appears to be a strategy for storing and delivering renewable energy to markets...
