Hydrogen / Power-to-X

Determining the minimum wall thickness for supercritical CO₂ pipelines requires consideration of multiple factors: internal design pressure, ductile fracture arrest, and dynamic pressure surges. While the design thickness for internal pressure can be readily calculated using ASME B31.4, the impacts of ductile fracture and surge pressures (similar...

Hydrocarbon energy remains essential to the global economy, with pipelines being the most efficient way to transport these resources. However, rising demand, aging infrastructure, and shifting operational conditions increase the risk of failures that can disrupt supply chains. To ensure reliability, proactive risk management is crucial...

The progressing energy transition and a fast buildup of the hydrogen pipeline backbone will play a major role in achieving net zero targets. The conversion of existing pipelines for the transport of hydrogen will play a key role in achieving the targets, which introduces new challenges for pipeline owners and operators. Pipeline repurposing...

The global oil and gas industry is at a pivotal point in its development. Climate imperatives, regulatory scrutiny, and technological advances are forcing a re-evaluation of long-established operational practices. At the core of this shift lies methane, the primary component of natural gas, which remains both a critical commodity and a major...

Pipelines form the backbone of many countries of the world – quietly transporting ty that fuels modern life. Yet, as the world advances in decarbonisation efforts, these established assets may need to accommodate alternative energy carriers. While they were designed to transport either oil or gas their future might lie in the transportation of...

Subsea pipelines such as in-field flowlines, trunklines, test lines etc. are an integral part of all offshore field developments. This paper covers innovative solutions for carbon footprint reduction from different phases of subsea pipeline life cycle i.e. design, construction and operation. Low carbon field developments are vital and heart of...

Validation of ILI performance is a critical component of any in-line inspection campaign to ensure that the ILI performance specification has been achieved. This allows high confidence integrity decisions to be made using the ILI data. The issues posed by the energy transition and the introduction of Hydrogen into existing gas networks present...

Hydrogen, a vital energy vector, is widely accepted as essential for decarbonising the global energy system. Hydrogen has a variety of roles to play in a low-carbon economy. Hydrogen can replace fossil fuels as a zero-carbon feedstock in chemical and fuel production [2]. It can also be used to extend the scope of climate transition to sectors that...

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...
