For the first time, ENTSOG is publishing hydrogen and natural gas system-level assessments as separate, self-standing documents within its TYNDP. This report complements ENTSOG’s draft TYNDP 2024 Hydrogen Infrastructure Gaps Identification Report. For an integrated sector perspective, the two reports can be seen in parallel to ENTSO-E’s Identification of System Needs (IoSN) Report.

This document is a draft version, prepared for feedback during a public consultation, expected in June or July 2025. After integrating stakeholder feedback, it will be submitted to ACER for its Opinion, as part of the draft TYNDP 2024 package, under Article 27 of Reg. (EU) 2024/1789 on the internal markets for ­renewable gas, natural gas and hydrogen. The underlying methodology, detailed in Annex D3, mentioned above, underwent extensive consultation between 19 June and 9 July, 2024.

Since its previous edition, ENTSOG’s TYNDP provides an overview of both the European hydrogen and natural gas infrastructure and its future developments. In TYNDP 2024, the main goal of the ­natural gas system-wide assessment is to measure the network’s resilience and security of supply under a series of stress cases. In practice, this is quantified by demand curtailment. The report additionally contains a yearly supply adequacy outlook, including a biomethane progress report.

The integrated gas network is mapped in line with a scenario that follows National Energy and ­Climate Plans and is considered central to TYNDP 2024 (National Trends or NT+). Demand and supply for this scenario are based on figures collected from the TSOs, translating the latest policy and market-­driven developments as discussed at national level.

Continued effort is necessary to further support sustainability, affordability and security of supply, in the current legal and geopolitical context. New regulatory provisions, like the updated legislation on internal markets for renewable gas, natural gas and hydrogen² are complemented by initiatives for alignment with industrial competitiveness goals. At the same time, diversification and ultimately independence from Russian ­volumes continue to be a high priority.

The results of this natural gas system assessment are also presented though an interactive visualisation platform, available here. ENTSOG is ­constantly working on improving the presentation of TYNDP simulations, to make results as ­accessible and user-friendly as possible.
