Abstract Scope |
The adoption of low-emission hydrogen as an energy source has been heavily reliant on cost reduction in production. However, a major obstacle to the widespread adoption of hydrogen energy is the lack of a reliable infrastructure for transportation and storage. Currently, steel is the preferred material for constructing large-scale gas infrastructure, and its cost-effectiveness has led to its consideration for transporting hydrogen through steel pipes. To enable the design of steel that is suitable for efficient hydrogen transportation, a thorough understanding of the fundamental interaction between hydrogen and steel is crucial.
In this study, we employ cutting-edge techniques, such as cryo-APT, high-resolution TEM, and ab initio simulation, to map the hydrogen distribution within the steel microstructure at the nanoscale. By combining experimental and simulation approaches, we aim to accelerate the development of materials designed for the hydrogen economy. |
