GRTgaz partners with CATALYSE to maximise hydrogen injection into existing gas transmission network

GRTgaz and CATALYSE have signed their first commercial contract to maximise the injection of hydrogen into the pipelines of the existing gas transmission network by developing a protective coating for the effects of hydrogen.

This signature took place in the heart of the collaborative innovation space ‘THE CAMP’, in Aix-en-Provence, in the presence of Anne CLAUDIUS-PETIT, Regional Advisor, Vice-President of the Commission Green Growth, Energy Transition, Energy and Waste, representative of Renaud Muselier, President of the Provence-Alpes-Côte d'Azur Region.

This contract follows a call for projects launched by GRTgaz in 2018, through its OPEN INNOVATION initiative, to maximise the injection of hydrogen into its network and preserve the durability of its existing steel pipelines. The CATALYSE company, located in La Ciotat, winner of this call for projects, has distinguished itself by offering GRTgaz an innovative pipe coating solution and the use of a robotic device for its application on curved surfaces. The contract signed with Catalyse, worth around €80 000, aims to limit the impact of hydrogen, which is known to cause an accelerated aging of the metal structure of the network pipes.

Concretely, the work will initially consist in carrying out a feasibility study, the development of a permeability test and the provision of a coating. The results of these first phases could eventually be used to deploy the solution developed by CATALYSE on the GRTgaz network and to interest other gas carriers in Europe and around the world, also involved in hydrogen injection.
