| Abstract: |
| As a zero-carbon energy source and a key technology to achieve the "carbon peaking and carbon neutrality goals", hydrogen energy has attracted wide attention worldwide in recent years. Liquid hydrogen storage has great advantages because of its characteristics of high hydrogen storage density, low storage pressure and high energy density. However, the industrial development of hydrogen energy is facing many key problems, large-scale, long-term storage and long-distance transport technologies have been the crucial problems in the process of liquid hydrogen application. So it is necessary to develop efficient liquid hydrogen storage and transportation technology and build large liquid hydrogen storage tanks with good thermal insulation performance. In this paper, the development status of large liquid hydrogen storage tank storage technology at home and abroad is reviewed, and the key problems such as cryogenic insulation and material thermal stress in storage of liquid hydrogen are analyzed. The challenges in storage and transportation technology of liquid hydrogen are pointed out, and the development direction of liquid hydrogen storage technology is prospected. |
