Design for the hydrogen core network (with logo)

In recent weeks, the transmission system operators (TSOs) have been working flat out on the final modeling of the hydrogen core network and its optimization. The total length of the optimized core network 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.

Podcast: What is the state of the H2 core network?

In the infrastructure podcast "What holds the world together", our Managing Director Barbara Fischer talks to NeulandQuartier GmbH about the planning status, the difficult question of financing and the upcoming construction of the hydrogen core network in Germany. If Germany wants to be climate-neutral by 2045, legislators must now set the right course for the financial viability of the core network. The risk: The success of the ramp-up of the hydrogen market is ultimately not in the hands of the network operators. Find out in the podcast what still needs to be changed in the draft law so that investors can invest in the network.

Explanatory film: How FNB Gas plans the hydrogen network

In order to develop the hydrogen network from the existing natural gas infrastructure, the planning must be all of a piece. Why this is so and how it works, we explain in this video.

Explanatory video: How hydrogen reaches the customer

To connect H2 generation sites with consumption sites, Germany needs a supraregional hydrogen network with connections to neighboring countries. Compared with new construction, it is cheaper, more resource-efficient and faster to develop the hydrogen network from the existing natural gas network. Where natural gas flows today, hydrogen may flow tomorrow. In our new series of explanatory films, we show how the conversion of the gas transport infrastructure to hydrogen works and what benefits it brings.

Planning status of hydrogen core network as of July 12, 2023 (without feed-in and feed-out)

On July 12, 2023, the transmission system operators published the planning status for a supraregional hydrogen core network by 2032. This current planning status does not yet correspond to the final design 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.

More than 350 interested representatives from politics and authorities, the energy sector as well as business and industry took part in the virtual event. The great response shows that hydrogen is not only essential for the […]

Video statement from FNB Gas Chairman of the Board Dr Thomas Gößmann on the publication of the Hydrogen Report

Germany must accelerate the ramp-up of hydrogen in order to secure supplies and promote climate protection. The hydrogen report submitted by the transmission system operators on September 1, 2022, in accordance with Section 28q of the German Energy Act (EnWG) shows how the necessary transport infrastructure can be built efficiently, quickly, and in a targeted […]

WEB messages on the expected hydrogen demand in the distribution network

As part of the Hydrogen Generation and Demand (WEB) market survey, numerous distribution system operators also submitted demand reports. This clearly shows that entire regions must be developed with an efficient hydrogen infrastructure at an early stage and on a large scale in order to be able to ensure the supply of a large number […]

Interdependencies in the conversion from natural gas to hydrogen

Similar to the L-/H-gas conversion, the conversion of network areas from natural gas to hydrogen involves interdependence between the parties involved. Efficient conversion of an area along a transmission system operator’s line in terms of network expansion can only be ensured if all connected customers (distribution system operators or industrial customers connected to the transmission […]

Possible process from hydrogen demand notification to hydrogen conversion roadmap.

The basis for planning the conversion of pipelines to hydrogen by the transmission system operators is initially the specific demand reports from various demand carriers (distribution system operators or industrial customers directly connected to the transmission system). These demand reports were secured via Memorandum of Understanding (MoU) in the NEP Gas 2022-2032 before they were […]

Sequence of the conversion to hydrogen at the end customer (private household)

The federal government is working to ensure that, as far as possible, every new heating system will be powered by at least 65% renewable energy (on balance sheet or physical) from 2024 [BMWK 2022]. This includes all renewable energies, i.e. also green and climate-neutral gaseous energy sources such as biomethane or green hydrogen. However, for […]

The path to climate neutrality on site

Each distribution network in Germany has its own regional characteristics. For climate neutrality to be achieved locally, these specifics must always be taken into account. Therefore, after the analysis and planning process in an initial phase, the expansion phase will begin to upgrade the distribution networks or convert them to other green and climate-neutral gases […]

Hydrogen network planning process in the context of a holistic energy system approach

An overview of the hydrogen network planning concept in the context of a holistic energy system view is shown in the figure. The concept presented for future hydrogen network planning will be integrated into the proven gas network development planning process. At the same time, by taking a holistic view of the energy system, new […]

Hydrogen testing concept

Based on the modeling results of the hydrogen variant 2032 in the NEP Gas 2022-2032, the transmission system operators perform a hydrogen test for the year 2032 for the reported demands of the distribution system operators. The objective of the hydrogen test is to identify network interconnection points (NCPs) or exit zones of the distribution […]

Transformation of transmission networks: arteries of the climate-neutral future

Today’s natural gas customer is tomorrow’s hydrogen customer. In the face of climate change, only one thing is certain: we must do everything in our power to limit the global rise in temperature. Fossil fuels therefore have no long-term future. At the latest, with climate neutrality targeted for 2045, natural gas can no longer play […]

Hydrogen network 2050: for a climate-neutral Germany
