NTT researches hydrogen transport through existing pipelines

Tokyo – (Business wire)-NTT Anode Energy Corporation (President and CEO: Teruyuki Kishimoto, Headquarters: Minato-ku, Tokyo, NTT Anode Energy) is a joint researcher to study safety measures for mass transportation of hydrogen through existing pipeline infrastructure. Announced a research and development project. Conducted jointly with the National Institute of Advanced Industrial Science and Technology (President: Kazuhiko Ishimura, Chiyoda Ward, Toyota Tsusho) and Toyota Tsusho Co., Ltd. (Representative: Ichiro Kashiya, Minato Ward). , Toyota Tsusho) is expected to contribute to the realization of a hydrogen pipeline transportation model that can be expanded globally.

“Hydrogen has emerged as an important part of the clean energy mix needed to ensure a sustainable future,” according to a paper published by the International Renewable Energy Agency. “But hydrogen through the new pipeline infrastructure. Large-scale and stable transportation in Japan faces problems such as construction cost and construction time for land acquisition. You can solve these problems by leveraging your existing pipeline infrastructure. This new study represents the next step in the proof-of-concept process for this model.

In this study, we will consider a double piping system in which a hydrogen pipeline is placed in an existing pipe (“sheath pipe”) buried underground. The factors that are measured and contribute to the development of technical standards are:

1. Field survey of hydrogen leak detection

2. Verification of detection of signs of abnormality

3. Establishing a control sequence to ensure safety

4. Performance evaluation of various hydrogen sensors in the real environment

Consider safety measures in anticipation of unstable situations such as rupture accidents and natural disasters during pipeline operation. In addition to considering the safety measures required for such use of existing pipelines, this study examines the profitability of such projects, including cost analysis of transportation. Energy input; Economic efficiency compared to other means of transporting hydrogen.

Based on the knowledge and data gained from this project, NTT Anode Energy and its collaborators will promote and establish technical research on safety measures for practical use. Ultimately, the project will include future supply of hydrogen to urban areas (public and commercial facilities, data centers, telecommunications buildings, fuel cell vehicles, hydrogen stations, etc.), pipelines utilizing telecommunications pipelines (cables, etc.) We also support supply via. With a view to a society that consumes a large amount of hydrogen through the development of CO2-free hydrogen, we will contribute to the development of smart cities and the establishment of hydrogen supply means through regional pipelines.

This project is carried out based on “R & D for full-scale dissemination of ultra-high pressure hydrogen infrastructure / R & D for international development / international standardization / R & D for examination of technical standards”.Hydrogen supply infrastructure, etc. ”New Energy and Industrial Technology Development Organization
