Existing natural gas pipelines provide an economic alternative for the transport of hydrogen
(H2) in an envisioned hydrogen economy. Hydrogen can dissolve in the steel and cause …

The rapidly increasing production volume of clean hydrogen creates challenges for transport
infrastructure. This study improves understanding of hydrogen transport options in Europe …

An X70 natural gas pipeline steel that is being considered for blended natural gas/hydrogen
gas service was evaluated in a high-pressure hydrogen gas environment. Fracture …

Fossil fuels continue to exacerbate climate change due to large carbon emissions resulting
from their use across a number of sectors. An energy transition away from fossil fuels seems …

Blending hydrogen in existing natural gas pipelines compromises steel integrity because it
increases fatigue crack growth, promotes subcritical cracking and decreases fracture …

This review summarizes the thermodynamics of hydrogen (H2) in mixed gases of nitrogen
(N2), methane (CH4) and natural gas, with a special focus on hydrogen fugacity. A …

Transporting hydrogen gas through the existing natural gas pipeline network offers an
efficient solution for energy storage and conveyance. Hydrogen generated from excess …

The increasing demand for energy and the global threat of climate change have driven the
search for alternative energy sources, with hydrogen emerging as a prominent substitute for …

As the world strives to achieve carbon neutrality, hydrogen is potentially expected to become
one of the major energy sources. Pipelines can be an efficient method for transporting large …

This paper focuses on the use of a variety of different small scale test methods to assess the
fracture resistance of the material in gaseous hydrogen and study susceptibility to subcritical …
