INNOVATIVE PROJECTS PLATFORM
To efficiently build on its Members' actions to promote or contribute to innovative technologies, regulation and business models, and partnerships across the value chain, ENTSOG has created the Innovative Projects Platform to map TSOs’ projects and partnerships on Research, Development and Innovation (RDI) activities for the energy transition.
This public platform provides information and links to enable exchange of best practices applied at national level and in some cases, across borders through partnership efforts.
These innovative solutions focus on topics such as repurposing infrastructure for renewable gases and projects for hydrogen, CCS and CO2 transport, biogas, energy system integration. These innovative applications support the achievement of the current EU goals of reducing GHG emissions and reaching the decarbonisation goal of net-zero by 2050.

Technology
Discover here how technologies can optimise the usage of the grid, make digital layer connections and support decarbonisation of the EU gas system. Technology R&D has a vital role in the energy transition. ENTSOG Members (TSOs) are developing new and innovative technologies to offer sustainable solutions for the gas sector.
Regulation & Business Model
Stay informed on how ENTSOG Members (TSOs) engage in development of the new energy products and services to foster uptake of renewable and decarbonised gases into the grid.
Partnership
Look at new partnerships and initiatives formed by ENTSOG’s Members (TSOs). They are actively working together as well as with various stakeholders on projects aimed at decarbonisation of the gas sector and of the whole EU economy.
Hydrogen
Hydrogen is a gas under standard conditions and there are also different hydrogen derivatives, such as ammonia and synthetic electrofuel. sHydrogen can be produced from diverse process technologies, such as electrolysis and steam-methane reforming (with or without carbon capture and permanent storage of this carbon to reduce emissions).
Repurposing for Renewable Gases
Repurposing of pipelines for renewable gases transport (e.g. hydrogen) is a cost effective way to meet decarbonisation goals and can be undertaken without compromising the ability of the natural gas network to ensure security of supply.
Biogas
Biogas is obtained via the anaerobic decomposition of the organic matter. After the process of upgrading, biogas becomes biomethane with the same quality standard as natural gas and can be transported via the existing grid infrastructure.
CCS and CO2 Transport
Carbon Capture and storage is the process of capturing CO2 from a set of possible sources, such as for example fossil fuel power plants, transporting it to a storage site, and depositing it underground on a permanent basis. The aim is to prevent the release of CO2 into the atmosphere.
Energy System Integration
Integrated infrastructure planning for electricity and gases is essential to support the decarbonisation of the energy system sector, particularly for facilitating the transport of renewable gases like hydrogen.
CNG
Compressed Natural Gas (CNG) is a fuel source that is made from compressing natural gas to less than 1% of its standard atmospheric volume. CNG combustion produces fewer climate-impacting gases than other fossil fuels.
Digitalisation
Digitalisation can bring various benefits to day-to-day operations such as enhanced control over the gas quality and cost reductions. TSOs look at data-driven solutions to boost performance, efficiency and competitiveness.
Heating & Cooling
Cutting the energy consumption in heating and cooling in buildings and industry can be achieved through various technologies. TSOs are working on developing cost-efficient solutions for the decarbonisation of this sector.
Certification of green gases
To ensure the cross-border scale up and tradability of renewable, decarbonised and low-carbon gases. This can be achieved via pan European Guarantees of Origin and Certification Schemes.
ENAGAS TRANSPORTE S.A.U, Veolia, Barcelona City Council
First sustainable urban cold recovery network at an LNG terminal
Barcelona LNG Cold Recovery Network aims to recover residual cold from the regasification process at the Enagás LNG terminal and convert it into sustainable energy for industrial, commercial and residential users. Developed by Enagás, Veolia and the Barcelona City Council, the project supplies low-carbon cooling through Southern Europe’s largest district cooling network. By recovering energy that would otherwise be lost, it supports decarbonisation, improves energy efficiency, and avoids more than 32,000 tonnes of CO₂ emissions annually.

Fluxys, OGE
TENP III Pipeline
TENP III aims to strengthen security of supply in Germany and Europe through the modernisation of the Trans-Europe Natural Gas Pipeline connecting Northwest Europe with Switzerland and the Italian gas market. Developed by Open Grid Europe (OGE) and Fluxys TENP, the 110 km pipeline increases transport flexibility through bidirectional flows and is fully hydrogen-ready. The project supports future hydrogen imports from Southern Europe while ensuring reliable energy transport and reinforcing cross-border connectivity.

FLUXYS
Zeebrugge Multi-molecule Hub
Zeebrugge Multi-molecule Hub aims to transform the Zeebrugge terminal into a multi-directional hub for natural gas, biomethane, hydrogen, ammonia and CO₂. Developed by Fluxys, the project will provide integrated import, export, transmission and terminalling services, supporting large-scale decarbonisation across Northwest Europe. Leveraging Zeebrugge’s strategic port location and extensive energy infrastructure, the hub will facilitate low-carbon hydrogen imports, CO₂ exports for permanent storage, and continued security of supply through diversified molecule flows.
DESFA S.A.
SmartSwitch project
H2 injection impacts major gas parameters, including pipeline pressure drop, flowrate, velocity, and most importantly, composition, GCV and Wobbe index, therefore prior to H2 addition to the grid, the installation has to achieve that the resulting blend will satisfy gas parameters. The above will be controlled by a smart hydrogen injection and operation system, which will keep hydrogen percentages at certain levels, while also deblending solutions will be applied for consumers with special needs in fuel purity.
SNAM SpA
Biomethane productions interconnection
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.
eustream, a.s.
Adjustment of existing eus pipeline SK-HU
Adjustment of the line of the transmission system for transmission of 100% H2 between Slovakia and Hungary will create possibility for H2 transmisson in the North -South direction. Project is part of the Slovak Hydrogen Backbone and the SEEHyCorridor inititative. Eustream has been conducting informal market survey. Close discussions with potential H2 producers and offtakers have resulted in conclusion of several Letters of Support or Memorandum of Understanding confirming their support to and interest in the Project implementation.
PLINACRO Ltd.
SAVA aquifer CO2 transmission
Besides directly reducing the CO2 emission, the project will also enable CO2 neutral production of H2 in a transitional period until the full decarbonisation is achieved when the production of H2 will be carried out entirely from the renewable energy through electrolysers. The location and the capacities of CO2 storing enable, if proven to be economically justified, receiving and storing of CO2 from the neighbouring EU countries (SLO, HU) and Energy Community countries (SER, B&H). Project enables the collecting and receiving CO2 from the Zagreb and Sisak-Moslavina area for storing in the central and western Sava aquifer and in the depleted oil and gas fields in that area.

REN
H2RENGRID - Transport Network
The project is intended to develop the necessary repurposing of the national transmission network (RNTG) for blending of hydrogen into the natural gas streams. According to the current national legislation and regulation, the network has to be able to receive gas mixtures of hydrogen and natural gas with hydrogen content of 10% v/v until 2030. For the national transmission network (RNTG), the investments are split into pipelines and inspection programs, control systems, AGI (above ground installations) equipment and analysers and metering equipment.

Teréga
Biomethane Reverse flow Projects
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.
