GTT has received an Approval in Principle (AiP1
) from ClassNK, the leading
classification society in Japan, for a new concept of membrane type containment system for liquefied
hydrogen (LH2).
As part of the energy transition towards a carbon-free future, the ability to transport hydrogen in liquefied
form at -253°C is one of the technological challenges to build a reliable, efficient and competitive hydrogen
supply chain.
To this end, GTT has developed a scalable containment system, which can be adapted to any size of LH2
carrier without major design modifications, as well as the cargo handling system, the design of which has
been validated on the basis of ClassNK rules accompanied by a risk analysis.
Philippe Berterottière, Chairman and CEO of GTT, declared: "We are proud to have obtained this new
approval in principle from ClassNK, whose in-depth technical and regulatory knowledge, as well as the
solid experience in the hydrogen field, demonstrate the relevance of GTT’s technology in this domain.
We
are convinced that the development of containment systems for the transport of liquid hydrogen is a key
element in accelerating the energy transition. GTT's R&D teams are determined to push back the
technological frontiers so that this solution is viable and rapidly available to the maritime transport and
energy players.”
Masaki Matsunaga, Corporate Officer and Director of Plan Approval and Technical Solution
Division of ClassNK, stated: “ClassNK has issued the AiP for the LH2 cargo containment system and
cargo handling system developed by GTT, following a review in accordance with our rules and guidelines
dedicated to LH2 transportation as well as verification of the risk analysis’ results. Anticipating that
hydrogen transport will play a significant role in a carbon-free society, we are delighted to participate in
GTT’s pioneering initiative through our expertise in safety assessment.”
