    Non-stop wind energy from the pipeline

    Mannesmann steel pipes transport (wind) power in the form of hydrogen.

Mannesmann for H2

Clean and safe.

Specially developed and qualified for the transport of hydrogen, the mechanical properties of our steel pipes exceed the requirements of the EIGA guideline and guarantee optimum safety and service life. Our group research institute, Salzgitter Mannesmann Forschung, is involved in testing and implementing the highest quality standards. We are also happy to put your individual requirements into practice.

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 steel pipes.

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 Line Pipe H2 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 for H2".

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 for H2" 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 for H2" 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.

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.
