Bureau Veritas (BV) has granted an approval in principle (AIP) for the design for a 150,000 cbm liquefied hydrogen (LH2) carrier and an AiP for the design of a cryogenic membrane containment system for liquefied hydrogen (LH₂) developed by GTT. The certificates were presented at the Hyvolution Summit 2024 trade show in Paris on 31 January 2024.

The new type of ship design was developed by GTT, TotalEnergies, LMG Marin and BV as part of a joint development project (JDP). The 150,000m3 capacity LH2 carrier concept design will be fitted with a membrane-type containment system from GTT.

The Motorship produced an in-depth feature on the project in July 2023. The ability to safely transport large volumes of hydrogen in liquefied form at -253°C (only 20°C above absolute zero) is one of the major technological challenges that the project partners aim to overcome to ensure a reliable, efficient, safe and competitive global carbon-free hydrogen value chain.
