The process for this edition included many updates, starting with the full application of the revised TEN-E Regulation. Consequently, ENTSOG adapted its Project Portal to facilitate the data collection for new project categories, with particular focus on the hydrogen-related infrastructures, their contribution to sustainability, as well as elements of the new hydrogen CBA methodology.

Another important development is the addition of a hydrogen-electricity interlinkage to the existing natural gas and hydrogen modelling. For the first time ENTSOG’s system-level assessments are based on the Dual Hydrogen Electricity Model (DHEM) developed in addition to the Dual Gas Model (DGM). Therefore, interactions between the hydrogen, natural gas and electricity sectors are better captured. Over 200 of the 326 investments in ENTSOG’s TYNDP 2024 are hydrogen projects. Building on the 2022 edition, the focus on hydrogen continues to increase, presenting a wider range of project types, including hydrogen subcategories for transmission, reception facilities, storage, electrolysers, and mobility projects. Other categories, such as biomethane and CO₂ infrastructure, make up the remainder of TYNDP 2024.

For the first time, ENTSOG evaluated the specific role of hydrogen infrastructure in achieving EU climate and energy targets in a dedicated report – the hydrogen Infrastructure Gaps Identification (IGI) report. The other important milestones for TYNDP 2024 were the publication of the Infrastructure report, followed by the publication of the Natural Gas System Assessment report, supported by various annexes and maps.

We are proud that TYNDP 2024 achieves the most advanced TYNDP assessment from an Energy System Integration perspective to date. Besides the addition of the new interlinkage mentioned above, this is also reflected in the close working relationship between ENTSOG and ENTSO-E in the development of the TYNDP 2024 Scenarios, the first phase of the TYNDP cycle. Given the importance of integrating the interface with the hydrogen sector, this cooperation will extend to include ENNOH representatives in 2026 and onwards.

Within the framework of the Clean Industrial Deal, growth and competitiveness go hand-in-hand with climate neutrality and strategic energy sovereignty. Molecules today offer affordable flexibility and reliable storage, even for the longer term, and the gas grids are an important part of an efficient, reliable and cost-efficient decarbonised energy system. The TYNDP 2024 assessment reiterates the potential the gas infrastructure provides for a robust and integrated European energy system.

On behalf of ENTSOG, we would like to thank all parties involved in the TYNDP 2024 journey. We hope you enjoy the TYNDP 2024 reports and maps. We look forward to your further contributions!
