Challenge
To operate a hydrogen-powered truck fleet, the hydrogen produced must be stored safely and made available in sufficient quantities. High final pressures, stable process conditions and continuous operation are crucial in this regard.

Solution
A multi-stage piston compressor is used to compress the hydrogen, enabling a controlled increase in pressure.

The system is designed to operate reliably even at high flow rates and under demanding gas conditions, ensuring a stable supply.

Implementation in South Africa
In a hydrogen project, green hydrogen from electrolysis processes is first compressed to a storage pressure of around 31 bar and then further compressed to up to 350 bar.

The compressor solution handles the first compression stage and ensures that hydrogen is continuously available for refuelling the truck fleet.

Results

• Reliable supply of hydrogen for the truck fleet
• Stable compression even at high flow rates
• Secure integration into the overall process
• Efficient operation of the refuelling station infrastructure
