The prominent classification society DNV has given GTT two Approvals in Principle (AIP1) for the design of a membrane type containment system for liquefied hydrogen (LH2) and for the preliminary concept design of an LH2 carrier.
These clearances are part of the deal with Shell, which was announced in February 2022, and set the way for the project’s further phases.
As part of the energy transition to a carbon-free future, one of the technological obstacles to building a reliable, efficient, and competitive hydrogen supply chain is the ability to transport very large volumes of hydrogen in a liquefied state at -253°C.
DNV’s early approvals support GTT’s technological advancements in LH2 containment and the preliminary design of an LH2 carrier.
The GTT Group has devised an LH2 containment system that meets current regulatory criteria and anticipates future advancements, as the International Maritime Organisation develops requirements for the transport and cargo of hydrogen.
Philippe Berterottière, Chairman and CEO of GTT, said: “We are very proud to have received these approvals from DNV, with whom GTT has had a close partnership for many years. Our LH2 carrier development project with Shell is very promising and this first step confirms the reliability and relevance of our solutions as well as our determination to make this technology viable and quickly available to maritime transport and energy players.”
Johan Petter Tutturen, Vice President Business Development Manager CO2 and H2 Carriers of DNV Maritime, said: “We are very pleased to have been asked by GTT to work on these AiP. Hydrogen, as an energy carrier and a fuel, is potentially one of the foundations of the energy transition. As such it is essential that industry is able to pursue the enabling technologies safely and with confidence. An AiP can help build this confidence by demonstrating that new solutions have been assessed based on long- standing, trusted and independent standards.”
