China releases the world's largest liquid hydrogen transport ship model

Recently, at the 2024 International Hydrogen Energy Industry Development Forum, two newly developed large-scale liquid hydrogen carrier design plans were released. The 180,000m3 and 20,000m3 liquefied hydrogen carriers released this time have completed the basic plan demonstration, It has also cooperated with the ABS classification society for certification. Among them, the 20,000m3 liquefied hydrogen carrier has been awarded the American Bureau of Shipping (ABS) Approval in Principle (AiP) certificate.

Hydrogen is non-toxic and does not produce greenhouse gases or pollutants when burned. In the future, the demand for hydrogen energy around the world will increase significantly. However, the production costs of hydrogen energy vary greatly between different countries and regions, which makes large-scale cross-border hydrogen transportation a very urgent technology. Efficient and high-purity liquid hydrogen transportation is the key to long-distance large-scale cross-border hydrogen transportation in the future important choice.

The 20,000m3 liquid hydrogen transport ship has a total length of approximately 160 meters, a ship width of 26.4 meters. Currently, the ship plans to use diesel propulsion, with a design speed of 14 knots, its main fuel is MGO (marine diesel), and the fuel tank is arranged in the middle of the hull. A proton exchange membrane fuel cell is installed in the engine room, and the evaporated hydrogen is used by the fuel cell to generate electricity to power the ship. The reliquefaction equipment and compressors are arranged in the cargo machinery space on the deck, and the GCU (gas burner) gas combustion device is placed in the chimney area.

The 180,000m3 liquid hydrogen transport ship has a total length of approximately 315 meters and a ship width of 54 meters, meeting the needs of large-scale cross-border transportation of hydrogen energy. The ship plans to use diesel for propulsion, with a design speed of 18 knots. The main fuel is MGO, and the fuel tank is arranged in the bow area. At the same time, LNG can also be selected as fuel for propulsion according to demand. A proton exchange membrane fuel cell is installed in the engine room, and the evaporated hydrogen is used by the fuel cell to generate electricity to power the ship.

This project helps the global shipping industry achieve the vision of zero carbon emissions and promotes the development of the global clean energy industry.
