Liquefied hydrogen tanker


Technology Description

A liquefied hydrogen tanker is a ship designed to transport liquefied hydrogen (LH2). Shipping LH2 is similar to liquefied natural gas (LNG), but as the boiling point of hydrogen (-253 °C) is much lower than that of natural gas (-162 °C), special thermal insulation is needed to minimise high boil-off gas rates, for example, using double-shell vacuum insulation tanks or membrane-based insulation systems. In addition, LH2 ships aim to use hydrogen boil-off gas as fuel for the loaded leg of the journey, providing a low emission shipping fuel and at the same time preventing venting it.

Relevance for Net Zero

Large liquefied hydrogen tanks may be required to enable hydrogen trading and medium to large scale storage in regions without geological conditions for underground storage.
