Green hydrogen for lorry filling station
Application | H2 Refuelling of a truck fleet
Country | South Africa

To operate a fleet of fuel cell lorries in a surface mine, the green hydrogen obtained from alkaline electrolysis must be stored efficiently. The hydrogen is compressed in two processes to a final pressure of around 350 bara. The first step involves a three-stage compression from an atmospheric inlet pressure to a storage pressure of 31 bara to enable post-compression.
The combination of water vapour-saturated hydrogen and a high volume flow poses a particular challenge. With the compressor solution, up to 850 kg of green hydrogen can be stored daily and is thus reliably available for the operation of the lorry fleet.
