The TYNDP 2024 will build on scenarios that are established with the help of an interlinked model including electricity. Also, the CBA methodology will be upgraded for the TYNDP 2024. ENTSOG aims for new CBA indicators for hydrogen infrastructure projects based on cross-sector assessments. ENTSOG is consulting its preliminary draft CBA methodology. This will allow for more complete assessments, including costs and ­benefits triggered by the projects for the overall energy system as well as the impact of projects on CO₂ emissions reduction.

Currently, ENTSOG and ENTSO-E are assisting the PCI selection ­process by conducting project-specific CBAs for electrolyser projects submitted as candidate under the revised TEN-E Regulation. Thereby, ENTSOG and ENTSO-E can showcase their cross-sectoral ­capabilities with an exercise similar to the proposed ­future CBAs. Therefore, ENTSOG is well on track in preparation for the upcoming TYNDP 2024.
