8 Promoters’ submissions for smart gas grid and other projects to ­TYNDP 2024

While Energy Transition projects were first included in ­TYNDP 2020, in ­TYNDP 2024 there is a further division replacing the ETR projects into hydrogen, smart gas grid and others.

In order to present more precise information in these evolving subcategories, ­ENTSOG provides a separate analysis of these subcategories in this chapter. This analysis includes only RET, BIO, SYN, CO2 and OTH investments. 29 projects have been included in ­TYNDP 2024 and are falling under the five mentioned subcategories.

It should be noted that, as for electrolyser projects (see section 6.5), the TEN-E Regulation does not require CO2 and smart gas grid projects to be part of the ­TYNDP in order to be eligible for PCI or PMI status.

8.1 Smart gas grid projects

For ­TYNDP 2024, promoters submitted 13 smart gas grid projects. More specifically, five BIO, one SYN and seven RET projects.

  • Three BIO projects enabling the reverse transportation between DSO and TSO of biomethane and two network development projects enabling biomethane production/injection into the gas grid;
  • Six RET projects regarding Retrofitting of existing gas pipelines and other network related assets for (bio-)methane-hydrogen blending and one investment regarding retrofitting of existing storages for H2 blending.

8.2 Other projects

For ­TYNDP 2024, promoters submitted 16 projects in the Others category. More specifically, 12 OTH investments and four CO2 investments.

  • Four OTH dedicated projects to reduce methane emissions in existing infrastructure, two projects enabling gas/electricity integration, four projects enabling the production, reception, injection, transportation or end-use ­supply of hydrogen and two projects dedicated to the conversion of natural gas network for CO2 transport or storage.

8.3 Further details on the ­TYNDP 2024 promoters’ submissions for RET, BIO, SYN, CO2 and OTH projects

Following the same structure as Chapter 6 and 7, this section provides more details on the investments under category RET, BIO, SYN, CO2 and OTH submitted to ­TYNDP 2024. The high level of investments should be considered in the context of the background described in section 6.4.

29 projects were submitted in total under these subcategories. Figure 51 provides the overview for this submission, compared to the previous ­TYNDP editions, emphasising the comparison for the above-mentioned subcategories.

IR figure 052

Figure 51: Comparison between TYNDP 2020, TYNDP 2022 and TYNDP 2024 – Smart gas grid and Other categories.

From Figure 52, the main points are:

  • Four new OTH projects and one new RET project were submitted to TYNDP 2024;
  • Three OTH projects were completed between the ­TYNDP 2022 and ­TYNDP 2024.

In addition:

  • One RET project was resubmitted in another category.1
  • One TRA project was resubmitted as BIO project.2
  • One OTH project was resubmitted as SYN project, one OTH project was resubmitted as H2E project and four OTH projects were resubmitted as CO2 project.3

1 Project RET-A-425 submitted as hydrogen storage (H2S-N-425).
2 Project TRA-F-1254 submitted as OTH (OTH-F-1254).
3 OTH-A-305 submitted as SYN-N-305, OTH-N-1230 submitted as H2E-A-1230 and OTH-N-456, OTH-N-551, OTH-N-554, OTH-N-1157 submitted as CO2.

8.3.1 Overview per type and status

From the total of 326 projects included in ­TYNDP 2024, 29 Smart gas grid and Other projects have been submitted for the subcategories RET, BIO, SYN, CO2 and OTH (9 %). These subcategories constituted 17 % of the total number of submitted projects in ­TYNDP 2022. This slight decrease is mainly due to the further splitting of the ETR categories and a more precise definition of the hydrogen categories, which gave promoters the opportunity to submit their projects accordingly.

The following figures and tables provide a statistical overview of promoters’ submissions (see ­TYNDP 2024 Annex A for further details) based on information such as the type of infrastructure or the FID/PCI status. Those reports reflect all the details entered as part of the data collection process by project promoters.

Figure 52 presents an overview of all the projects accepted for inclusion in ­TYNDP 2024 per type of infrastructure for subcategories RET, BIO, SYN, CO2 and OTH.

Figure 53 shows the submissions sorted by the maturity status. The majority of projects are Less-Advanced (69 %), six projects have the Advanced status, while only three out of the 29 projects acquired the FID status.

Due to the information collected, it has been possible to identify projects submitted for ­TYNDP 2022 that were not active anymore but for which promoters had missed to previously report the information to ­ENTSOG or that were deleted or not resubmitted (see Table 10).

For a better analysis, a comparison of the maturity level between the ­TYNDP 2022 and the ­TYNDP 2024 submission is presented in Figure 54.

For this ­TYNDP, a majority of smart gas grid and other projects has the Less-Advanced status. In the previous ­TYNDP, the highest number of projects were also recorded with the Less-Advanced status. For FID, a slight reduction can be seen, while the number of Advanced smart gas grid and other projects reduced as well. In the context of this ­TYNDP, projects with commissioning expected at the ­latest by 31 December 2029 and either in permitting phase or FEED phase, obtained the Advanced ­status.

In ­TYNDP 2024, three projects have the FID status:

  • Two were Less-Advanced in ­TYNDP 2022;
  • One was already FID.

More details on the maturity status for these subcategories can be found in Chapter 4.

8.3.3 Analysis of project schedule

Figure 58 shows the distribution of projects included in ­TYNDP 2024 according to the expected (first) commissioning year, in Figure 59 also in an aggregated way. The majority of projects falling under the smart gas grid and other subcategories is planned to be commissioned within the next 6 years (21 out of the 29 or 72 %), while the last commissioning year is 2040.

All of the projects having FID or Advanced status are expected to be commissioned by 2030.

Additionally, several years are not displayed in the following graphs, indicating that there are no projects to be commissioned during those periods.

Feasibility, FEED, Permitting, FID, Construction and Commissioning

The Feasibility Study phase, the start and end dates, either past or expected, have been provided for 20 projects. The average duration of the Feasibility Study phase for these projects is 10 months with the highest average duration in case of CO2 projects (19 months) and the lowest average duration for SYN project (1 month).

In addition, 6 projects have indicated the completion of the feasibility study until the end of ­TYNDP 2024 project collection period, while eight projects have started the feasibility before the end of the project collection period, with expected finalisation date until the end of 2024. The rest are expected to finalise the feasibility study until December 2029.

Regarding the FEED phase, the start and end dates, either past or expected, have been provided for 28 projects. The average duration of the FEED phase for smart gas grid and other projects is 23 months with the highest average duration in case of BIO projects (63 months) and the lowest average duration in case of SYN projects (1 month).

One project has indicated the finalisation of FEED phase until the end of ­TYNDP 2024 project collection period. In addition, six projects have started FEED phase before the end of the project collection period but are still ongoing with the latest finalisation date in December 2032.

The remaining 21 projects have started the FEED phase within 2024, while the latest end of the FEED phase is December 2037.

In case of the Permitting phase, the start and end dates, either past or expected, have been provided for 28 projects. The average duration of the permitting phase for these projects is 25 months, with the highest average duration for BIO (56 months) and the lowest average duration in case of SYN projects (14 months).

More specifically, two projects have completed the permitting phase until end of the project collection period. Two projects have started permitting phase before the end of the project collection period but are still ongoing with the latest finalisation date in December 2029, while the remaining 24 projects will start their permitting process after the beginning of 2024 with the latest finalisation date in December 2038.

The FID date, either past or expected, has been provided for all of the smart gas grid and other projects. Five projects have obtained the FID until the end of the project collection period4. The graph below shows the distribution of projects per FID date. The average FID date is 3 January 2026 (see Figure 60).

4 Even though three projects have officially the FID status in ­TYNDP 2024, two more projects are supposed to receive it by the end of 2023 and thus, were included in the analysis.

IR figure 061

Figure 60: Cumulative distribution of projects per FID date – BIO, CO₂, OTH, RET and SYN.

Regarding the Construction phase, the start and end dates, either past or expected, have been provided for 28 projects. The average duration of the Construction phase for these projects is 33 months, with the highest average duration in case of BIO projects (69 months) and the lowest average duration in case of CO2 and SYN projects (21 months).

Two projects have started their construction prior the end of the ­TYNDP 2024 project collection period. The remaining 26 projects have foreseen the start of the construction after the beginning of 2024 with latest end date in December 2039.

Figure 61 below provides all the information for the different phases described above.

Figure 12: Evolution of projects from ­TYNDP 2022 to ­TYNDP 2024 (Smart Gas Grid and Other category).

Of the four Smart Gas Grid and Other projects submitted already having the FID status in ­TYNDP 2022:

  • Two projects were completed (OTH-F-541 and OTH-F-632);
  • One still in progress but no FID (OTH-F-743);
  • One was not resubmitted (BIO-F-437).

Of the 17 Smart Gas Grid and Other projects submitted already having the Advanced status in ­TYNDP 2022:

  • One still has the Advanced status (OTH-A-1269);
  • One moved from Advanced to Less-Advanced due to delay or rescheduling and submitted under a different infrastructure type (RET-A-425 became H2S);
  • 15 were cancelled or not resubmitted by the promoter.

Of the 42 Smart Gas Grid and Other projects submitted already having the Less-Advanced status in ­TYNDP 2022:

  • One was completed between TYNDP 2022 and TYNDP 2024;
  • Two got the FID after the ­TYNDP 2022 project collection (BIO-N-497 and BIO-N-624);
  • Three moved from Less-Advanced to Advan­ced, however investment OTH-N-1230 submitted as H2E;
  • 12 are still planned and four are in progress while still maintained the Less-Advanced status;
  • 20 were cancelled/not-resubmitted.

Finally, only eight Smart Gas Grid and Other projects stated their ­scheduled status:

  • 3 investments are delayed;
  • 5 investments are on time.

8.3.4 Investment costs

Investment costs are for project promoters in many cases commercially sensitive information and might have the potential to negatively affect the competitive position of project promoters vis-à-vis contractors.

As part of the transparency process adopted, ­ENTSOG has collected information from promoters on indicative investment costs for all submitted projects.

In line with the TYNDP 2024 GPI, the cost data submitted by the project promoters for the projects to be included in the ­TYNDP is made public by ­ENTSOG unless the data is deemed confidential by the respective project promoters.

Smart gas grid and Other category represent almost 3 % of the total ­TYNDP 2024 investments in terms of cost. The highest share of costs is represented in the less-advanced status (61 %) while the share of less advanced projects for all the Smart gas grid and Other projects is around 70 % (see Figure 63).

As seen in Figure 64, OTH projects (41 % of the total number of projects in this category cover the highest share of the Smart gas grid and Other projects project costs (63 %). It should be noted that CO2 (4 projects) and SYN (1 project) are not included due to confidentiality reasons. The rest of the subcategories were submitted as aggregated data.

In addition, almost half of the total capital expenditures for Smart gas grid and Other projects will take place until 2030 (78 %), with a peak in 2030 of more than 5 billion euros (see Figure 65).
