GTT, TotalEnergies, LMG Marin and Bureau Veritas Unite for Maritime Hydrogen Transport

A consortium comprising GTT, TotalEnergies, LMG Marin, and Bureau Veritas has achieved a significant milestone in the Joint Development Project (JDP) focused on enabling the maritime transport of liquefied hydrogen (LH2). The project's success is underscored by the issuance of two crucial Approvals in Principle (AIP) from Bureau Veritas, representing a key advancement in tackling the technological complexities of large-scale hydrogen shipping.

The primary objective of the Joint Development Project is to devise a cryogenic membrane containment system for liquefied hydrogen, addressing the challenges associated with transporting hydrogen in a liquefied state at extremely low temperatures (-253°C). The consortium aims to establish a reliable, efficient, and competitive hydrogen supply chain, contributing to global efforts for a carbon-free future and facilitating broader energy transition initiatives.

Each collaborator has brought its expertise to the project, developing an innovative Large-Scale LH2 Carrier concept. GTT played a key role in designing the cryogenic membrane containment system, while LMG Marin contributed to the development of the 150,000 m3 vessel design tailored to operational requirements. TotalEnergies provided specifications on design codes, vessel limits, propulsion mode requirements, and CO2 emissions criteria. Bureau Veritas played a critical role in conducting risk assessments, ensuring regulatory compliance, and validating the designs against Bureau Veritas rules.

These successful approvals represent a crucial step towards unlocking the potential of maritime hydrogen transport, addressing the need to transport significant volumes of liquefied hydrogen to establish a robust hydrogen supply chain supporting various industries and applications. The collaborative effort underscores the commitment of key players in the French industry to tackle the challenges of global hydrogen shipping, highlighting the potential for international collaboration in driving sustainable solutions.
