How maximize hydrogen (H2) blending potential in natural gas (NG) networks, supporting European energy system decarbonisation? The answer lies in the need of a systemic, multi-disciplinary approach to make NG infrastructure resilient to the challenges of tomorrow. Industrial and research players’ competences are required. In this framework, THOTH2 consortium focuses on energy measurement value chain and instruments’ ability to accurately measure physical parameters of H2NG mixtures with increasing H2 percentages, up to 100%. Including gas TSOs, DSOs, metrological and research institutes and academia, THOTH2 consortium has all competences and skills to reach the goals of i) define standards to evaluate the metrological performances of measuring devices at different H2 blending rates (up to 100%), ii) verify safety and durability of the same devices, and iii) suggest future needs to overcome the observed barriers and limitations. SNAM competences in managing NG assets are essential for the coordination and synergic integration of the 14 partners, recognized as experts in NG and H2 industry (GRTGAZ, GAZ-SYSTEM, Enagás, INRETE), metrology (CESAME, INRIM, METAS), H2 blending technologies and measuring devices design, engineering, and R&D activities (UNIBO, INIG, FBK, ENEA, CSIRO). The communication and dissemination strategy by GERG will give visibility to project’s results, including contributions to Mission Innovation 2.0 and EURAMET projects. THOTH2 vision will lead to an acceleration towards H2 economy, contributing to REPowerEU and NextGeneration EU objectives. The project impact potential includes the establishment of a R&D Hub center, including THOTH2 partners and Advisory Board members, to translate into valuable results achieved by the project, aiming to i) the development/update of international standards, ii) foster innovation in the field of H2NG blending measuring devices, and iii) supporting H2 value chain development leveraging on the EU gas infrastructure

To accelerate the transition to a low-carbon economy while exploiting existing infrastructure, hydrogen can be injected to the natural gas network. However, the there are many technical and regulatory gaps that should be closed and adaptations and investments to be made to assure that multi-gas networks across Europe will be able to operate in a reliable and safe way while providing a highly controllable gas quality and required energy demand. Recently, the European Committee for Standardization concluded the impossibility of setting a common limiting value for hydrogen into the European gas infrastructure recommending a case-by-case analysis. In addition to this, there are still uncertainties related to material integrity on pipelines and networks components with regards to a reduced lifetime in presence of hydrogen. Existent results from previous and ongoing projects on the hydrogen readiness of grid components should be summarized in a systematic manner together with the assessment of the existent T&D infrastructure components at European level to provide stakeholders with decision support and risk reduction information to drive future investments and the development of regulations and standards. The SHIMMER project aims to enable a higher integration and safer hydrogen injection management in multi-gas networks by contributing to the knowledge and better understanding of hydrogen projects, their risks, and opportunities. - To map and address European gas T&D infrastructure in relation to materials, components, technology, and their readiness for hydrogen blends - To define methods, tools and technologies for multi-gas network management and quality tracking, including simulation, prediction, and safe management of transients, in view of widespread hydrogen injection in a context of European-wide context -To propose best practice guidelines for handling the safety of hydrogen in the natural gas infrastructure, managing the risks

The European submarine networks are vital critical infrastructure for the EU member states. This submarine cable and pipeline network is crucial for the European society and any failure or damage to it could potentially have an enormous effect on the societies. Due to the rapidly evolving threat and geopolitical landscape, especially with incidents like the sabotage of the Nord Stream 1 and 2 gas infrastructure, organizations overseeing critical infrastructure face significant challenges. They must handle intentional threats while also grappling with growing problems caused by accidental and natural factors as well as climate change. These issues can worsen the effects of deliberate actions. To address these challenges effectively, it is crucial for these entities to implement resilience-enhancing measures. The aim of VIGIMARE is to strengthen the resilience of Critical Infrastructure operators against threats to the European submarine critical infrastructure by developing, testing and evaluating an innovative solution to enhance security and reduce risks of physical and cyber-attacks on submarine cables and pipelines. This will be accomplished by 1) mapping submarine systems, surveying cables and landing stations, and assessing vulnerabilities in the European submarine critical infrastructure network, 2) develop an automated threat detection approach, creating a real-time shared awareness of the surface above the submarine infrastructure to promptly indicate incidents to both critical infrastructure owners and member states authorities. By integrating a comprehensive resilience ecosystem with real incidents at sea, the project seeks to 3) identify early warning signals, support analysis, and pinpoint potential response activities to address physical, cyber and hybrid threats. The result will be enhanced resilience for submarine critical infrastructure owners, supporting authorities to enforce the CER and NIS2 directives implementation in the EU member states.
