GTT takes an important step in the field of liquid hydrogen transport

with two DNV classification society principle approvals

Paris – July 28e2022. GTT has obtained two approvals in principle (AIP1 ) from the main classification society DNV for the design of a membrane-type containment system for liquefied hydrogen (LH2) and for the preliminary 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 steps of the project.

As part of the energy transition towards 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 for establishing a reliable, efficient and competitive hydrogen supply chain.

The approvals in principle issued by DNV validate GTT’s technological advances in LH2 containment and preliminary design of an LH2 carrier.

The GTT Group has designed an LH2 containment system that meets current regulatory requirements and anticipates future developments, with requirements for hydrogen transport and cargo being developed by the International Maritime Organization.

Philippe Berterottière, Chairman and CEO of GTT, said: “We are very proud to have received these approvals from DNV, with whom GTT has maintained a close partnership for many years. Our LH2 The carrier development project with Shell is very promising and this first step confirms the reliability and relevance of our solutions as well as our desire to make this technology viable and quickly available to maritime transport and energy players.”

Maritime said: “We are very happy to have been asked by GTT to work on these AiPs. Hydrogen, as an energy vector and fuel, is potentially one of the foundations of the energy transition. enabling technologies safely and confidently. An AiP can help build that trust by demonstrating that new solutions have been evaluated against long-standing, reliable, and independent standards.

Carl Henrickson, Managing Director Shipping & Maritime Technology, Innovation & Digitalization

of Shell International Trading and Shipping Company said: Shell is delighted to partner with GTT to deliver this groundbreaking work. As we see the development of LH2 Cargo containment systems are a key element in accelerating the energy transition in hard-to-reduce sectors. We’ve worked with GTT since the early days of developing the first LNG carrier, and it’s been great to see how their

expertise can be applied to enable transport of liquid hydrogen. The effort by everyone to get this new membrane containment system through this key development hurdle has been tremendous and is a testament to the excellent working relationship between everyone involved. This technology will support the safe and efficient scaling of bulk liquid hydrogen transportation by sea, which in turn will help unlock hydrogen as a fuel source for the future. »
