Paris - June 14th, 2022. GTT group, the technological expert in membrane containment systems dedicated to the transport and storage of liquefied gases, takes first place in the INPI's list of ETI1 patent applicants, for the third consecutive year, with 55 patents published in 20212. In the ranking of the Top 50 patent applicants in all categories, GTT is in the 30th place.

This ranking highlights GTT's strong innovation dynamic, with a R&D budget representing 10% of the Group's turnover and 26% of its workforce in 2021. Innovation is one of the Group's fundamental values and is at the heart of its development strategy.

The continuous improvement of the GTT group's technologies aims to optimize the energy performance of its customers. For example, over the last ten years, the technological solutions developed by the Group have enabled greenhouse gas emissions from LNG carriers to be halved. Today, the GTT Group is working on technical and digital solutions for the propulsion of vessels using liquefied natural gas, which can reduce the CO2 emissions of ships by about 20%. With Elogen, its subsidiary specializing in the design and assembly of membrane electrolysers for the production of green hydrogen, GTT confirms its highly technological positioning committed to building a sustainable world.

Philippe Berterottière, Chairman and CEO of GTT, declared: "We are proud to be recognized, for the third consecutive year, as the most innovative mid-sizecompany by the INPI. This success is first and foremost that of GTT teams, who put their passion for innovation and technical excellence at the service of the Group's customers and their transformation challenges in the critical context of the energy transition. This first-placeranking also recognizes the success of French technological excellence, which is fortunate to be able to rely on a pool of top-qualitytalents but also on an economic, academic and regulatory ecosystem that fosters innovation and research."
