Launching of world’s first liquefied hydrogen carrier ship

The SUISO FRONTIER, the world’s first liquefied hydrogen carrier ship, has launched and is currently in a demonstration phase led by HySTRA (CO2-free Hydrogen Energy Supply-chain Technology Research Association).

The ship’s storage tanks enable the transport of liquefied hydrogen cooled to -253°C at 1/800 of its original gas state volume. For safety reasons, critical infrastructure is required to monitor the state of the liquefied hydrogen in the storage tanks.

As part of its industry-leading lineup of hermetic sealing components, SCHOTT manufactures Eternaloc® feedthroughs and electrical penetrations that provide reliable function of instruments and control infrastructure in nuclear, liquefied gas, and compressed gas applications, where safety is critical. Working in close collaboration with Kawasaki, SCHOTT developed fiber-optic penetrations as well as compact Eternaloc® S-type feedthroughs for the ship’s vacuum insulation system.

Eternaloc’s® structural design consists of double-sealed electrical glass-to-metal sealed feedthroughs in a compact housing as well as double sealed fiber optic feedthroughs. The secondary seal, the pressure barrier, can support continued function without leakage in the unlikely event of a compromised primary seal.

Made with compression glass-to-metal sealing technology that is optimized for harsh environments, the feedthroughs undergo a variety of type tests including vibration and seismic load tests to verify their ability to withstand stress and help keep critical systems intact, even in extreme circumstances such as very low temperatures. To withstand long and difficult voyages, SCHOTT uses a double glass-sealed hermetic seal structure, which has been used in nuclear power plants, LNG cargo pumps, etc., and is known for its robustness.

The SUISO FRONTIER successfully proved the design, production, and functionality of a ship equipped with specialized tanks for transporting liquefied hydrogen. Kawasaki is now moving forward with a full-size carrier ship design for liquefied hydrogen, which is currently in a basic design phase.

The development of this product was supported by Japan’s National Institute of Research and Development New Energy and Industrial Technology Development Organization (NEDO).
