The energy transition needs hydrogen to deliver the ambitious goals
Hydrogen is a climate-neutral, storable gas that can be transported over long distances. That is why OGE is committed to facilitating hydrogen deployment for you. Together we will shape the future.
Gas is an indispensable energy carrier
Only 20 % of Germany's final energy consumption is electrical – the rest is based on molecules such as oil and gas. That is why climate-neutral gases are of central importance for decarbonisation.
Transport of large amounts of energy at low cost
One gas pipeline can transport as much energy as eight high-voltage power lines. Moreover, the investment required for hydrogen infrastructure up until 2050 will be much lower than the costs of expanding the electricity infrastructure.
Long-term and flexible storage
Germany’s total electricity storage capacity can only bridge a 36-minute blackout while the country’s gas storage facilities are able to store sufficient supplies for three months of demand.
Hydrogen for a climate-friendly energy system
OGE's natural gas pipeline system already connects various sources of supply with large energy consumers and storage facilities. We are now gradually converting these pipelines to hydrogen. By repurposing existing lines and building new sections, we can use existing infrastructure quickly and cost-effectively.
In this way, our gas infrastructure can become the largest storage and redistribution system for renewably electricity, thus helping to mitigate fluctuations in solar and wind energy to allow power generation to follow a seasonally independent course.
*Blue hydrogen production differs from grey fossil hydrogen production in that it is linked to a carbon capture and storage (CCS) process which prevents the release of CO2 into the atmosphere.
Turquoise hydrogen is made using a process called methane pyrolysis to produce hydrogen and solid carbon instead of CO2 emissions. In order for the process to be carbon-neutral, the heat supplied to the high-temperature reactor has to come from renewable energy sources and the carbon has to be permanently stored or used.
Our goal is a Germany-wide, publicly accessible hydrogen network with a large number of suppliers and users. To this end, we are developing numerous partnerships and working on hydrogen projects with key national and international industry partners.
How can I get my hydrogen project connected to the grid?
The development and expansion of a nation-wide hydrogen grid in Germany is essentially planned by the future hydrogen network operators as part of a joint process managed by FNB Gas. This process is based on the hydrogen sources and sinks identified by the Hydrogen Production and Demand Survey ("Wasserstofferzeugungs- und -bedarfsabfrage" – WEB). If you want to report your hydrogen production capacities/demand to OGE separately from the WEB process, you can do so using the form provided on this page. This will allow us to include your projects in our future plans, even retrospectively.
Where technical facilities are connected to the grid, contracts must be concluded between you as the connection user and OGE regarding the connection and grid usage. In addition, the minimum technical requirements for connections to Open Grid Europe’s grid and gas pressure regulating and metering stations (for connections in the hydrogen grid) have to be observed.
What will hydrogen transportation cost?
It is not yet possible to specify costs and charges. An overview of the terms and basic principles of cost recognition and fee determination for network operators who have opted for a regulated regime (opt-in regulation) can be found in section 28o of the Energy Industry Act (EnWG) and in the Hydrogen Network Charges Ordinance (WasserstoffNEV).
The German government is looking to subsidise the hydrogen infrastructure at the start of the market ramp-up, which will have an impact on the actual level of charges for hydrogen shippers. The aim here is to avoid high charges and sudden increases.

What will be the quality of the hydrogen in OGE's future hydrogen network?
Code of Practise G 260 (A) entitled "Gas Properties" published by DVGW, the German Gas and Water Industry Association, defines two groups: Group A (hydrogen content >= 98 mol-%) and Group D (hydrogen >= 99.97 mol-%). The quality of group D conforms to the requirements of EN 17124 for hydrogen-powered fuel cell vehicles.
OGE’s hydrogen infrastructure, which will be gradually expanded by repurposing existing pipelines and building new pipelines, will transport Group A hydrogen. The limits for accompanying substances were largely defined on the basis of the specification currently in place for accompanying substances in natural gas. Technically, it is possible to convert Group A into Group D by using purification techniques.
Can existing gas pipelines be used for hydrogen?
The steels used to make the natural gas pipelines earmarked for conversion are basically suitable for hydrogen. Many of today's pipelines were already used in the past for hydrogen in the form of so-called town gas which contained high levels of hydrogen. Given our longstanding experience with hydrogen in Germany, we know that our pipelines chosen for the planned hydrogen network are suitable for hydrogen. Depending on the design, it may be necessary to replace valves or other components, but this will much less expensive than building infrastructure from scratch.
