Hydrogen core network

On November 15, 2023, FNB Gas e.V. submitted the draft application for the hydrogen core network to the Federal Network Agency and the Federal Ministry of Economics and Climate Protection. This marks the next milestone in the realization of the core network.

Planungsstand-12.07.2023 Design_KernnetzAgentur

Key data of the hydrogen core network design

The total length of the optimized core grid is around 9,700 km . Of this, 710 km is accounted for by pipelines from 17 other potential hydrogen network operators, which the TSOs received as part of the opportunity to comment on the first planning status by 28.7.2023. The core network consists mainly of converted natural gas pipelines (approx. 60%). The investment costs amount to € 19.8 billion €. The feed-in and feed-out capacities amount to around 100 GW and 87 GW respectively. The draft of the core grid thus fulfills the goals of a Germany-wide, expandable, efficient and quickly realizable hydrogen grid by the target year 2032, as set out in the EnWG amendment on the hydrogen core grid. This puts Germany at the forefront of infrastructure development in Europe.

What are the next steps?

The Federal Network Agency consulted the FNB’s draft application via its website by 08.01.2024. An evaluation and review is currently being carried out by the authorities. The TSOs will take the results into account in their final joint application for the core grid in consultation with the BNetzA. The submission deadline for the joint application for the core network was set by the BNetzA in accordance with Art. § Section 28 r para. 2 sentences 1 and 2 EnWG to May 21, 2024. The prerequisite for the submission of the joint application for the FNB is the legal anchoring of a financing model for the hydrogen core network that is suitable for the capital market. The corresponding amendment to the EnWG is currently in the parliamentary process (find out more here).

Once the official joint application has been submitted, it will be consulted and reviewed again by the Federal Network Agency. Approval is granted within two months of the complete application being submitted.

The core network is the starting signal for the hydrogen infrastructure in Germany with a focus on the transport level – comparable to a highway. In the first stage, it forms the basic framework for the development of the hydrogen infrastructure in Germany. This basic framework is to be further developed by means of integrated network development planning for gas and hydrogen in the second stage – similar to the federal and state highways with connections in cities and municipalities. You can find out in detail here what will happen after the publication of the draft.

Development of the hydrogen core network

The hydrogen core network will be built up successively until 2032, starting with the first pipeline conversion in 2025. The planned commissioning of the annual expansion stages of the core network in the years up to 2032 can be seen in the following diagram.

Looking back: From vision to mission

Since January 2020, the TSOs have been actively working on the development of the German hydrogen network. Many of the earlier considerations and experiences have been incorporated into the planning and design of the hydrogen core network. The most important milestones to date at a glance:

July 2023

On July 12, 2023, the transmission system operators published the planning status for a supraregional hydrogen core network by 2032. This planning status does not yet correspond to the final draft of the hydrogen core network. The route variants presented will be evaluated and optimized in subsequent steps, taking into account reports received as part of the “opportunity to comment” from potential hydrogen network operators. The pipelines shown have a length of around 11,200 km. The TSOs expect the hydrogen core network to be smaller after optimization.

A total of 309 hydrogen projects were considered in the hydrogen core network scenario. The feed-in capacities for hydrogen total 101 GW. Other feeds include, in particular, imports via ship terminals where hydrogen transported in another form, such as LOHC or ammonia, is fed into the hydrogen grid as a gas. The core grid can provide 87 GW of exit power for hydrogen supply.

Opportunity for network operators to comment by July 28

Based on the published planning status for the hydrogen core network, operators of distribution networks, hydrogen network operators and operators of other pipeline infrastructures pursuant to § 28r para. 5 EnWG until July 28 to comment on and report further hydrogen infrastructures for the hydrogen core network. For the feedback to info@fnb-gas.de, the TSOs have provided a corresponding form on the website of the TSO Gas. Subsequently, the reported pipeline infrastructures are checked for their use in the planning of the hydrogen core network by the transmission system operators and taken into account in the final modeling, provided that they meet the legal and technical requirements for integration into the hydrogen core network and the infrastructure is necessary for the transport requirements.

Opportunity for other stakeholders to comment to BMWK by July 28.

The amendment to the EnWG provides for the central hydrogen sources (generation and import) to be connected to the main consumption centers and hydrogen storage facilities via a Germany-wide hydrogen core network. As a basis for this, a scenario was developed under the leadership of the BMWK and the BNetzA and coordinated with the TSOs, within the framework of which the modeling of the hydrogen core network takes place. Based on the current planning status, the German Federal Ministry of Economics and Climate Protection is also giving states, associations and other stakeholders until July 28 to comment on the development of a Germany-wide, efficient, quickly realizable and expandable hydrogen core network. This gives stakeholders – where necessary and in line with Section 28r (4) EnWG-E and the scenario – the opportunity to present arguments for the inclusion of further pipeline infrastructures in the hydrogen core network. Comments may be submitted to the following BMWK email address: WASSERSTOFFKERNNETZ@bmwk.bund.de

Core network as starting point for future integrated hydrogen network planning

The hydrogen core network is the starting signal for the hydrogen ramp-up. It will cover the needs according to the criteria defined by law. Any additional requirements should be taken into account promptly in a second step as part of the future regulatory process for integrated network development planning for gas and hydrogen. The TSOs had already submitted corresponding proposals in this regard in September 2022 with the publication of the hydrogen report in accordance with Section 28p of the Energy Industry Act (EnWG), which were drawn up jointly with the distribution system operators, among others.

More information

In an official FAQ, the BMWK has already addressed and answered initial questions about the core network. To answer your questions, FNB invite industry representatives from companies and associations to a virtual hydrogen lunch at Microsoft Teams on July 14, 2023 at 12:00 pm. Please log on to info@fnb-gas.de. You will then be sent the dial-up data.

The hydrogen core network as the first expansion stage forms the basic framework of the future hydrogen infrastructure. Following this, the processes for integrated gas network planning (hydrogen and natural gas) must now be anchored in law as quickly as possible so that future requirements for hydrogen can be incorporated into further network planning. As part of the interim report pursuant to Section 112b (1) sentence 2 EnWG(BT-Drucksache 20/7915) of July 27, the German government outlined initial proposals for a concept for the further development of the hydrogen network infrastructure.

July 2022

The hydrogen network 2032 presented in the interim status for the NEP Gas 2022-2032 shows the result of the modeling of a Germany-wide hydrogen network for the year 2032 based on the Memorandum of Understanding (MoU) requirements, the results of the NEP Gas 2020-2030 and the pipeline reports of the transmission system operators and other potential hydrogen network operators as well as on existing parallel pipeline systems in the transmission system.

Transmission system operators were able to conclude letters of intent with more than 250 project sponsors for a transport demand of 165 TWh, of which about 90% can be connected to the hydrogen grid in 2032. The modeling results in a hydrogen network with a pipeline length of 7,600-8,500 km by 2032.

At the same time as the H2 Grid 2030, the FNB publishes the hydrogen grid for a climate-neutral Germany (in short: H2 Grid 2050), and shows that they can construct such a grid in an economically efficient and reliable manner at moderate investment costs. The H2 network 2050 has been further developed by the TSOs from the “Visionary Hydrogen Network” published in January 2020. For the first time, the H2 grid 2050 is based on detailed grid planning.

The 2050 H2 network is about 13,300 km long, of which more than 80 percent is based on converted gas pipelines. It can provide an energy quantity of 504 TWh (calorific value), with a peak offtake of around 110 GWh/h of hydrogen.

December 2021

With the Hydrogen Grid 2030 (in short: H2 Grid 2030), the TSOs are demonstrating solutions as to how transport requirements can be fulfilled on a supraregional basis in a dynamic development of the hydrogen market in the near future. Compared to the H2 starter grid, the H2 grid 2030 is significantly more extensive and now also takes into account the significantly higher volume target for national hydrogen requirements set out in the National Hydrogen Strategy, in the order of 90 to 110 TWh. The basis is a scenario for the production and use of hydrogen in Germany developed together with the consulting firm 4Management based on the recognised dena Leitstudie I (TM95).[1]

The scenario on which the H2 grid 2030 is based includes a hydrogen demand of 71 TWh (calorific value). The network is about 5,100 km long, of which about 3,700 line kilometers are based on converted gas pipelines.

[1] FNB Gas (2021): Scenario framework for the NEP Gas 2022-2032, p.39

May 2020

From vision to implementation: the planning for a hydrogen network in the NEP Gas 2020-2030 confirms essential parts of the visionary H2 network of January 2020. The NDP Gas consultation document published by the transmission system operators on 4 May 2020 includes concrete steps for the development of an H2 network. With the conversion of the first pipelines starting as early as the end of 2022, the core for a Germany-wide H2 network will gradually be created by 2030 (especially in North Rhine-Westphalia and Lower Saxony).

The starting point for the H2 Start Net 2030 were the projects identified in the market partner survey of the FNB Gas on green gas projects with 31 reports. Among these are projects of large industrial customers, such as steel mills and projects at refinery sites. The H2 start-up network 2030, with a length of over 1,200 km, essentially connects demand centers in North Rhine-Westphalia and Lower Saxony with green gas projects for hydrogen production in northern Germany.

All things begin with a vision. In January 2020, the FNB presented its vision for a first Germany-wide hydrogen infrastructure in the form of a network map for the first time. The network has a total length of 5,900 km by 2050, based 90% on existing natural gas pipelines. With the publication of the visionary hydrogen network, the FNB wanted to contribute to the hydrogen strategy announced by the German government and show a first concrete step towards the future hydrogen economy.
