INNOVATIVE PROJECTS PLATFORM

The objective of this reverse flow project from DSO grid to TSO grid, is to ensure the integration of excess biomethane in the distribution grid into the transmission grid. The project is a virtual aggregation of three future physical projects establishing reverse flows from DSO grid to TSO grid. When supply of biomethane in the high-pressure distribution grid exceeds demand, high-pressure compressors lift the gas to the TSO grid (20/40 bar to 80 bar), where odor in the gas is removed also. These are reverse flow facilities.

The project consists of the interconnections of the new biomethane productions to existing Snam Rete Gas network. The provisions regarding connections of biomethane plants to gas networks introduced by the Italian Regulatory Authority for Energy, Networks and the Environment (ARERA) with Resolutions n, 220/2023/R/gas and 131/2024/R/gas.

Reverse flows will be needed to allow biomethane injected in the distribution to flow back to the transmission grid when the biomethane injected locally exceeds local demand. These network adaptations will enable to maximize the volume of biomethane injected into the gas system and reach the national target for renewable gas (15% of gas consumption in 2032). Teréga expects 1 reverse flow unit every year from 2024 (7 completed by 2032) for an estimated reverse flow of 0,5 TWh/year.

IMPULSE 2025 project aims at implementing a smart multi-energies system to interconnect different energy networks (gas, power, heat) to create synergies and improve energy efficiency. It includes studies and the building of a pilot demonstrator. 2 phases: Phase 1 (2019-2024) development of a model and optimization tool to identify the optimal configuration of a smart multi-energies system. Phase 2 (post 2025) study of the operational feasibility to confirm estimated gains.

The scattered production of renewable gas will take an increasing part in the gas mix. Grid adaptations and extensions will be required to connect these production units to the transmission network. These network upgrades will maximise the volume of biomethane injected into the gas system and reach the national target for renewable gas (15% of gas consumption in 2032). Teréga expects 3 to 5 connection projects per year (around 40 completed by 2032) for an estimated production of 1,6 TWh/year.

Network adaptations will enable to maximize the volume of biomethane injected into the gas system and reach european target for renewable gas production set by Repower EU. Grid extensions will be required to collect this generation and backhaul facilities will allow the excess energy to be absorbed when supply exceeds local demand. It can be estimated that around 162 backhaul installations and mutualised compressors −90% in D/T (Distribu-tion/Transmission) and 10% in T/T (Regional Transmis-sion/Principal Transmission infrastructures)− would be re-quired, i.e. a financial envelope of €479 million by 2030.
 

Project envisages construction of a 2 km hydrogen pipeline and facilities connecting Green H2 production plant of Società Chimica Bussi (SCB) to SGI high-pressure gas network. This connection will provide:

• H2 / CH4 blending services for grid injection of excess H2 production initially up to 1% (in vol.);
• H2 modulation/ storage services allowing retrieval of H2 from pipeline, hence operating as storage infrastructure for other SCB uses.

GRTgaz SA and Creos Deutschland GmbH are collaborating to create a 100% pure hydrogen infrastructure, connecting the Saar (Germany), Lorraine (France) and the Luxembourg border. This 70 km-long infrastructure will be capable of transporting up to 20,000 m³/h (60 MW) of pure hydrogen via retrofitted existing gas pipelines.

Hydrothermal gasification is a technology converting wet biomass and treating organic wastes and residues. It uses the water contained into the biomass as the reaction environment in its supercritical phase to produce a synthesis gas. In Europe, several stakeholders are developing or currently operating pilot plants of this technology. The technology could reach industrial scale by 2023-25 with modular installations scaled between 0,5 and 6 t/h.

The overall objective of the project is to increase knowledge about the accuracy and durability of commercially available gas meters after exposure to renewable gases (biogas, biomethane, hydrogen, syngas and mixtures with natural gas). This should lead to the improvement of existing meter designs and flow calibration standards. The project started in June of 2019 and will last for 3 years, and is funded by the European Metrology Programme for Innovation and Research (EMPIR).
