About the project
An immediate shift in focus toward energy independence and a transition to green energy is required by the EU’s energy strategy. However, technological, economic, and normative constraints must be overcome for innovative solutions to be accepted by society. In order to decarbonize the EU and decouple intermittent renewable energy supply and demand while maintaining the stability of the electric grid, green hydrogen (H2) is an essential component of an alternative fuel. Since huge H2 volumes can be carried over long distances and gas cross-border transmission capacities are notably high, enhancing countries’ exports/imports of renewable energy, H2 blending in existing gas infrastructure can play a key role in enabling the green transition. This project aims to provide answers to how new mixtures may coexist with existing installed devices in the gas value chain, such as measurement ones, in order to promote H2 blending in the future. The question could be addressed by specific testing. The normative framework, which includes testing procedures for mixes of hydrogen and natural gas (H2NG), is still being built.
When conveying pure H2 or H2NG mixtures, THOTH2 intends to fill the gaps in normative and standards related to procedures and protocols for assessing the performances and determining the limits and tolerances of State of the Art (SoA) measurement instruments in transmission and distribution systems. In order to test various measuring devices installed in the gas transmission and distribution grids, such as gas meters, gas volume conversion devices, pressure and temperature transducers, gas quality analysers, and gas leak detectors, at various operational conditions, THOTH2 will develop specialized methodologies. The findings of THOTH2 will be useful in forming suggestions for the Technical Committees (TC) of International Standard Bodies, Gas Transmission and Distribution Operators (TSOs, DSOs), Manufacturers of Measuring Devices, and Calibration Service Providers.
The project is funded by the Clean Hydrogen Partnership and coordinated by SNAM. It involves the participation of 14 Partners from all over Europe.
