GTT moves ahead on liquefied hydrogen carrier designs

Gaztransport & Technigaz (GTT) has led world shipping in terms of LNG construction is now making advances into the liquefied hydrogen (LH2) trades.

GTT has been granted two approvals in principles (AIPs) from classification society DNV for the design of a membrane type containment system for liquefied hydrogen and for the preliminary concept design of an LH2 carrier.

These approvals are part of the agreement with Shell, announced in February 2022, and pave the way for the next stages of the project.

As part of the energy transition to a carbon-free future, the ability to transport very large volumes of hydrogen in liquefied form at -253°C is one of the technological challenges to establishing a reliable, efficient and competitive hydrogen supply chain.

Japan’s Kawasaki Heavy Industries has become the first company in the world to develop and operate an LH2 carrier.

Many other companies are now looking to develop their own vessels and this nascent seaborne trade is forecast to take off.
