The Optic Fibre-Based Hydrogen Leak Control Systems project OPTHYCS has just been launched. Hydrogen has emerged as a required fuel and commodity needed for the decarbonization of the generation, distribution, storage, and energy consumption. Through the EU Hydrogen Strategy, the EC recognised the important role of hydrogen, and the need for the hydrogen market to be significantly scaled up. The boost in hydrogen production and its introduction in the energy market has raised an important challenge: reinforce security of hydrogen and prevent eventual greenhouse gases (GHG) emissions across its value chain.

In this sense, the OPTHYCS project will aim to develop new sensor technologies for continuous leak detectors based on optical fibre sensors technologies which will lead to anticipate eventual hydrogen applications risks, from production to storage and distribution, both in new infrastructure, working with pure H2, and in natural gas repurposed installations and pipelines, contributing to a safe and economically viable implementation of H2 production, transport and storage processes.

The OPTHYCS project is built upon 3 conceptual areas:

  • Technology pillars analysis and definition of new sensor technology,
  • Validation of key use cases (pipelines, Hydrogen refuelling stations and midstream sites such as compression and metering stations) of the new technologies in 3 different controlled validation sites, and
  • Aspects of the technologies derived from the use cases, including the assessment of the security and environmental risks evaluations and regulatory framework, and a scalability and cost efficiency study.

GERG is an association that represents R&D interests and coordinates corresponding efforts of its
members on a EU level. GERG membership includes EU TSOs, DSOs, major NG suppliers, universities and research institutes, as well as international standardisation organisations.

About the Clean Hydrogen Partnership

The Clean Hydrogen Partnership is supporting research and innovation (R&I) activities in hydrogen technologies in Europe. It aims to accelerate the development of advanced clean hydrogen applications ready for market, across end-use sectors such as energy, transport, building and industry, while strengthening the competitiveness of the clean hydrogen value chain. The members of the partnership are the European Commission, fuel cell and hydrogen industries represented by Hydrogen Europe and the research community represented by Hydrogen Europe Research.

The OPTHYCS project has received funding from the Clean Hydrogen Partnership under grant agreement No. 101101415.
