Messer Schweiz AG, a leader in industrial and medical gases, sought a more efficient and low-maintenance method for hydrogen trailer refueling. Traditional mechanical compressors at the Visp facility required large amounts of electricity and frequent service interventions. GRZ Technologies addressed this challenge by developing and deploying a new class of hydrogen compressor powered by industrial waste heat, radically reducing energy use and service requirements.
The Challenge: High Costs and Heavy Maintenance from Mechanical Compression
Hydrogen trailer filling demands continuous, high-reliability compression from low pressure to trailer pressure. Prior to GRZ’s involvement, the Visp facility relied on mechanical compressors that were:
- Energy-intensive, driving significant electricity consumption
- Maintenance-heavy, with moving parts prone to wear
- Operationally costly, especially with increasing H₂ demand
- Hard to scale, limiting throughput expansion
The goal was to deliver the same industrial performance with far lower operational costs and greater long-term reliability.
