This is also the first strategy for the global shipping industry to reduce greenhouse gas emissions. Hydrogen, as a carbon-free clean energy, is one of the new fuels that has attracted much attention and is vigorously developed by the industry. Correspondingly, the concept of hydrogen fuel-powered ships emerged as the times require and has become a hot topic in the current industry.

At present, hydrogen is used as a fuel, and it is mainly stored on board in the form of high-pressure gaseous state, low-temperature liquid state, solid-state alloy adsorption and organic liquid. There are some problems in the above-mentioned hydrogen storage methods: for example, the liquid storage at atmospheric pressure and full cooling at -253°C requires the installation of ultra-low temperature liquid hydrogen storage tanks and ultra-low temperature piping systems and valves to serve them, and the initial investment is too high. Another example is to store in a high-pressure gaseous state above 350bar, and a high-pressure hydrogen tank needs to be installed on board, but currently limited by materials, pressure and other reasons, the volume of a single tank is about several cubic meters, and the hydrogen storage density per unit mass is also low.
