Overview

Transporting liquid nitrogen efficiently presents an unusual combination of operational and vehicle-design requirements. The product must remain at approximately-196°C, while the vehicle needs equipment capable of supporting autonomous, fast and safe unloading without unnecessarily reducing available space.This case study shows how Gardner Denver Transport Solutions worked with Vos Logistics, Air Liquide and Iveco on an LNG-powered transport application in the Netherlands. The solution combines a Hydrapak and hydraulic driven generator, with the generator precisely adjusted to the LNG engine. The compact hydraulic-driven setup can be installed behind the truck cab, helping preserve room for larger LNG tanks and supporting vehicle operating range.

 

Challenge: Combining LNG Mobility with Liquid Nitrogen Transport

Air Liquide was pursuing more sustainable logistics operations and planned to replace half of its trucks with LNG-powered vehicles over a seven-year period. Vos Logistics, already experienced with LNG trucks, became its transport operator for the first two Iveco Stralis NP LNG trucks operating from Eindhoven with trailers carrying liquid nitrogen.The application created several requirements:
  • Transport liquid nitrogen at approximately-196°C.
  • Enable the liquid product in the trailer to be released autonomously, quickly and safely.
  • Integrate loading and unloading technology with the LNG-powered vehicle.
  • Use vehicle space efficiently so that LNG tank capacity, and therefore operating radius, would not be unnecessarily compromised.

Solution: Hydrapak and Hydraulic Driven Generator

Gardner Denver Transport Solutions supplied loading and unloading technology based on Hydrapak and a hydraulic driven generator. The resulting compact, versatile configuration could be mounted behind the truck cab, helping maximize the space available for LNG tanks.For this application, the hydraulic driven generators were precisely adjusted to the Iveco LNG engine. The equipped trucks could then support autonomous liquid nitrogen unloading as part of vehicles used around the clock for nitrogen transport.This demonstrates how auxiliary transport equipment can be integrated with an alternative-fuel vehicle while addressing both liquid gas transfer requirements and packaging constraints.

Customer Quote

"We started driving for Air Liquide in April 2017. From the outset, we looked at whether we could realize the sustainability ambitions of Air Liquide. In consultation with Iveco and Gardner Denver Transport, we have now succeeded."

Vos Logistics

"In Vos Logistics we have found a partner who thinks along with us and helps us achieve our goal of achieving a 50% reduction in CO2 emissions in our logistics operation"

Impact and Results

The application enabled Vos Logistics and Air Liquide to combine LNG-powered transport with the equipment required for liquid nitrogen distribution.Specific benefits documented in the case study include:
  • Compact installation: equipment can be mounted behind the truck cab.
  • More space for LNG tanks: the configuration helps maximize tank size to benefit vehicle operating radius.
  • Autonomous unloading: onboard technology enables release of liquid product from the trailer without relying on a separate setup.
  • Application-specific integration: hydraulic driven generators are adjusted to the LNG engine.
  • Operational capability: the system supports quick and safe liquid gas unloading.
The case study also places the project within Air Liquide's broader goal of achieving a 50% reduction in CO₂ emissions in its logistics operation. This is presented as the customer's objective rather than as a measured emissions reduction attributable specifically to the equipment.

Key Takeaways

  • Hydraulic-driven auxiliary equipment can support liquid gas transfer on LNG-powered trucks.
  • Compact equipment packaging is particularly valuable when installation space competes with LNG fuel-tank capacity.
  • Matching the hydraulic generator to the vehicle engine is an important part of application integration.
  • The solution supported liquid nitrogen transportation at-196°C and autonomous loading/unloading requirements.
  • The project illustrates how transport-equipment design can support a fleet customer's wider sustainability strategy.
