Network Customers
Your connection to the ONTRAS hydrogen network
Are you a hydrogen supplier, final consumer, storage facility operator or network operator interested in connecting to our pure hydrogen network? We would be pleased to support the implementation of your project.
Start network for hydrogen
ONTRAS is committed to the development of a hydrogen infrastructure in central and eastern Germany. As part of the Germany-wide hydrogen core network, the ONTRAS H2 starter network is the starting point: We are starting with around 600 kilometers of hydrogen pipelines, most of which are to be realized by converting existing natural gas pipelines and by building new sections. We want to start in central Germany: the Leipzig area will be connected to the central German chemical triangle, the industrial centers in Saxony-Anhalt and Lower Saxony, the Berlin area and the Meissen industrial arc. ONTRAS projects with a planned commissioning will be reviewed once again as part of the integrated gas and hydrogen network development plan, as required by law.
If you are interested in connecting to the hydrogen network please get in touch with us. For concrete projects and connection plans to our ONTRAS hydrogen grid, please use the grid connection data sheet for hydrogen injection* or for hydrogen offtaking*. If you are looking to blend, you can find important information on the following site: blending of hydrogen.
*Note: The current documents will be available again shortly.
Reserve Hydrogen Transport Capacity
By reserving capacity, you can secure early planning certainty for your future hydrogen transport needs. Details of the reservation fee are available in the capacity reservation tariff sheet.
Once transport services become available, a capacity booking will replace the reservation. Further information on the reservation process and timeline can be found in:
Current Status of Reserved Hydrogen Transport Capacity
Market Information 3 builds on the previously published Market Information 1 and 2. It provides an update on current reservation levels, remaining available transport capacity in each capacity zone, and recent developments relating to Germany’s hydrogen core network. Several capacity zones have also been adjusted.
Capacity Reservation
This page provides access to the request form for reserving capacity in Germany's hydrogen core network. The reservation request form can be used to submit requests for the network point types listed below.
Network Point Type Available for Reservation through THE
- Cross-Cluster Transport (CCT)
Network Point Types Available for Reservation through the Hydrogen Core Network Operators
- Offtake Point for End Consumers (NAP)
- Cross-Border Interconnection Point (GÜP)
- H2 Terminal
- Domestic Production Facility
- Hydrogen Storage Facility
Please select the network point type that best matches your project and submit your request using the form provided. Binding reservation requests have been accepted since 19 March 2026.
A Know Your Customer (KYC) verification process will be carried out alongside the assessment of your request.
The capacities published in Market Information 3 reflect the available transport capacities as of 23 July 2026, based on infrastructure scheduled to be commissioned by the end of 2029. These capacities provide the foundation for the hydrogen market ramp-up in all regions that will be connected to the hydrogen core network by that time.
As the hydrogen market develops, the capacity framework within individual clusters may evolve. Market participants are therefore expressly encouraged to submit requests that exceed the published capacity offering for a given capacity zone or for cross-cluster transport services.
All requests will be reviewed by the network operators on a case-by-case basis. Where justified by market demand, this may lead to a reassessment and adjustment of the available capacity offering.
For cross-cluster transport services, such reassessments could reduce the applicable clearing price or eliminate it altogether, provided that all transport requests for the respective gas hour can be accommodated.
Gas quality
The gas quality requirements for hydrogen as the base gas are defined by DVGW standard G260. Hydrogen has now been established as the 5th gas family. There are two groups, which differ in purity:
- Group A: Fraction H2 ≥ 98 mol% to < 99.97 mol%
with minor components of the 2nd gas family for repurposed pipelines - Group D: Fraction H2 ≥ 99.97 mol% to ≤ 100 mol%
in line with DIN EN 17124 for fuel cell application
Our network is the ideal starting point for the development of a hydrogen transport infrastructure. We can only develop a hydrogen network that optimally covers future demands together with our customers. Let's get talking about it!
