Hydrogen Infrastructure

Process description

Hydrogen can be stored after production, transported via gas networks and industrial pipeline systems, and made available.

If the hydrogen is not produced directly at the site of industrial or private use, it must be transported, regardless of the type of production. Various technical methods are used for this: for example, as gas in high-pressure containers, as liquid gas in insulated containers, further processed into methanol and ammonia, or in liquid form in a carrier medium.

Pipeline transport has established itself as the most economical method, since existing networks are used in some cases. To be fed into pipeline networks, the hydrogen must be compressed to the operating pressure of the pipeline network. In this process, piston and turbo compressor stations at certain intervals ensure that the pressure is maintained despite flow losses in the pipeline.

To compensate for differences between hydrogen production and consumption or to balance out fluctuations, hydrogen can be stored in caverns, for example. Cavern storage can assume dimensions of 70 m in diameter and a height of 400 m.

In addition, there is the possibility of storage in other underground storage facilities. In some cases, 3,800 tons can be stored there to feed local industry as well as private households.

Requirements

• Processing and compression up to 1,000 bar.

• Supply of chemicals, power plant technology and filling stations in the low-pressure and high-pressure range (70 mbar to 700 bar).

• Storage at over 200 bar.

• High demands on tightness - gas tightness at high pressures.

• Safety of the valve.

• Long service life even at high pressures.

Solutions

The handling of hydrogen requires high material quality, safety and process-proven valves. KLINGER Schöneberg valves offer all this and more.
