Future-proof energy carrier.
Transport and storage of hydrogen
Hydrogen is available in almost unlimited supply and is ideally suited as an energy carrier for the transport and storage of renewable energy. Power-to-gas technologies make energy usable where it is needed. The safe transport of hydrogen plays a central role in a future with an increasingly renewable energy mix. Be on the safe side with Mannesmann H2ready®.
Mannesmann Line Pipe GmbH is a member of the Fuel Cell and Hydrogen, E-Mobility Network which forms part of the EnergyAgency NRW. We are also a member of various other German networks to promote the development and bringing to market of hydrogen technologies together with other partners.
Power ahead with hydrogen
Mannesmann steel pipes support the future of fuel cell technology. The energy carrier of the future, H2, only becomes truly environmentally friendly with the conversion of renewable energies (e.g. wind energy) into hydrogen. After that, the intended purpose is merely secondary. In terms of mobility, where hydrogen is used or is likely to be used for cars as well as for aircraft, trucks, buses, trains or ships, it is where it is needed quickly, safely and cleanly. With the Mannesmann H2ready® pipeline.
We transport climate.
Mannesmann steel pipes are an element of eco-friendly industrial innovation and applications. The declared vision is to avoid carbon dioxide by using green hydrogen as a raw material in industrial processes. Various companies and branches of industry are setting a good example in this respect, for instance the Salzgitter AG SALCOS project (low carbon steelmaking). In any event, the hydrogen is already there. With the Mannesmann steel pipe "Mannesmann H2ready®".
Non-stop wind energy from the pipeline
Mannesmann steel pipes transport (wind) power in the form of hydrogen. Eco-friendly hydrogen can be produced using power-to-gas technology, as this involves the use of renewable energies (e.g. wind, sun). Water is split here into oxygen (O2) and hydrogen (H2) by means of electrolysis. The environmentally friendly hydrogen produced by this means serves as a chemical storage medium and can be reused as fuel or for reconversion into electricity. In addition, the power-to-gas process enables subsequent methanation, with which regenerative natural gas can be produced from the hydrogen downstream. No matter whether hydrogen is to be stored or transported - the Mannesmann steel pipe "Mannesmann H2ready®" is designed for both. Regardless of this, Mannesmann's H2 pipeline naturally also enables the transport of conventional methane or gas which has largely been decarbonized by electrolysis and converted to hydrogen.
Highly specialized adaptation.
The mechanical material properties of our pipes are designed for transporting hydrogen. They present clearly defined strength levels in quasi-static tensile tests.
Even in the long-term result, slow strain rate tensile tests show no negative influence of hydrogen on our "Mannesmann H2ready®" steel pipes.
Utmost corrosion resistance.
For lasting durability in hydrogen transport, the inner surface is free of any discontinuity (in accordance with ISO 3183). Furthermore, internal points which are vulnerable in relation to hydrogen are reduced to a minimum by the phosphorus and sulphur content levels being guaranteed to remain below those specified in the EIGA guideline. A carbon equivalent that has also been further reduced ensures excellent weldability of our pipe material. This guarantees a long service life and leads to low-maintenance operation.
Insignificant permeation
According to scientific literature excerpts, hydrogen permeation through steel pipes (and thus the loss of media) is negligible. [1] states that with plastic pipelines as currently used as standard for low pressures in the distribution of natural gas, hydrogen emissions of up to 13.83 m3/km per year can occur with line pressure of 7.5 bar at room temperature.

Flexible pipeline design.
In order to achieve greater freedom in pipeline design, we offer grades up to X70 (according to API 5L) or L 485 going beyond the recommendations of the EIGA guideline 1). If required, suitability for the hydrogen atmosphere (e.g. 100 bar, room temperature, 100% pure gaseous H2) is proven in a comparative test for the application.
This enables pipeline routes to be achieved that were previously not economically feasible. In particularly demanding ambient conditions - worldwide.

Technical Information
On the way into the future.
Mannesmann H2ready® for Gasunie
In Wolfsburg, two state-of-the-art gas-fired power plants will safeguard the future supply of energy to the VW plant and the city of Wolfsburg. To ensure that they can also be operated with hydrogen in the longer term, Mannesmann H2ready® pipes from Mannesmann Line Pipe have been used in the construction of the supply pipeline. In total, it consists of almost 1,900 pipes with individual lengths of up to 18 meters, grade L360NE, mainly with a diameter of 406.4 mm. Running parallel to an existing pipeline, the new pipeline was laid over a length of 9 km using a trenchless method that is particularly gentle on the environment. For this purpose, however, the pipes were additionally wrapped in GRP. A total of 14 HDD (Horizontal Directional Drilling) boreholes were drilled in the vicinity of rivers, canals, roads and railroad lines.
