GRTGAZ is a European leader in NG transmission and a world expert in gas systems. In France, the company operates more than 32,000 km of buried pipelines to transport gas from suppliers to consumers connected to its network. Within GRTG, the R&D Center for Energy (RICE) is the division dedicated to R&D in Research, Development, and Innovation for gas infrastructure. GRTG-RICE provides tested and proven industrial applications, as well as technical offers based on the development and the sharing of innovative ideas, scientific knowledge and technical expertise developed within the framework of the gas infrastructure, covering 3 main areas: 
1) Integrity of metallic and non-metallic networks;
2) Improvement of operational performance, industrial safety and asset management of industrial infrastructure;
3) Analysis, odorization, detection and metering of gases.

GRTG-RICE oversees the Use cases testing and validation (WP4), testing H2 sensors in real environments using different gas (blend of NG/H2, pure H2) related to the use cases.
As leader of this WP, GRTG participates with the other partners in the definition of the different KPIs for each use case and will supervise the testing and evaluation of sensors.


FHa is a private non-for-profit technological centre promoted by the Regional Government of Aragón (Spain), other public bodies and private companies. Its team manages R&D projects in cooperation with regional, national and EU companies. FHa has been supporting the regional strategy for the uptake of H2 and fuel cell technologies, publishing the Hydrogen Master Plan in Aragón, and showcasing the whole H2 chain from production to the efficient use, from renewable sources. FHa also develops training from students to technicians and D&C activities. FHa oversees the Open Science in the Project and oversees the HRS use case in WP4.


Lumiker is an entity that has been developing advanced photonic sensors for biotechnology analysis, FBG and Brillouin critical location and distributed fibre optic solutions since 2010 and the first company in the world to develop the measurement of current utilizing the FARADAY effect with our own technologies. Lumiker provides condition monitoring solutions based in photonic and fibre optic sensors for critical asset management.
Lumiker oversees WP2 for the development of H2 detection sensors based in FBG technologies, to detect low and high level H2 ppms in Gas utility environments; and for the development of H2 FBG Interrogator.


Tecnalia Research and Innovation is the first private applied research centre in Spain and the 5th in Europe. In the field of Hydrogen, Tecnalia has been working since 2002 on the development of several technologies within the whole value chain of H2, including H2 generation, distribution, transport, storage, and end uses. Moreover, Tecnalia has a department for Hydrogen Technologies aimed at coordinating and developing specific technological solutions for the H2 value chain. Tecnalia has a wide experience in EU projects on the H2 field such as DEMCAMER, ReforCELL, FERRET, FluidCELL, BIONICO, HyGrid, etc. It is worth to mention that the collaboration between Tecnalia and Eindhoven University of Technology in the last years has created the H2SITE spin-off company, for commercializing Advanced Membrane Reactor able to produce high purity H2 on customer’s premises.

Tecnalia is involved mainly in WP2 for the development, optimization, and characterization of the specific sensing coatings for FBG H2 sensors. In addition, Tecnalia oversees the lab verification and validation of the novel sensor, and the results achieved will be used for the validation task at the different end-users (WP4).
