Hydrogen in Mobility

Process description

For electric vehicles with fuel cell technology, hydrogen is used as an energy carrier in many applications: Forklifts, cars, buses, trucks or even rail vehicles.

To ensure that refueling can be carried out safely and quickly, precise pressure equalization is necessary. The same applies to the hydrogen filling of tank containers in filling stations. Pneumatically driven valves ensure optimum distribution of the hydrogen in the container tanks.

Various valves are required in the filling station for control, automation and fulfillment of safety functions. Typically, manual valves for maintenance and pneumatic shut-off valves in explosion-proof design are used.

Depending on the refueling and acceptance concept of the plants, the valves must withstand pressures between 50 and 1,000 bar. In addition, the valves for fast refueling procedures must withstand temperatures down to -40°C.

Requirements

• High pressure and low temperature requirements.
• Refueling down to -40°C.
• Storage and refueling up to 1,000 bar.

Solutions

Compatibility with hydrogen is necessary for all valve components that come into contact with the medium and is mastered by KLINGER Schöneberg through the appropriate selection of materials.
