Hydrogen liquefier - large scale
High-capacity trains up to 150 tonnes per day, leveraging in-house turbomachinery, optimized heat exchangers combined into compact cryogenic cold boxes.
For mega-hubs and global trade, Air Liquide supplies large-scale liquefaction trains from 60 tpd to 150 tpd, lowering specific power consumption below 7 kWh/kg.
Leading-edge cryogenic technology
Liquefaction is a critical enabler for the transportation and distribution of hydrogen to where it holds the most value. Our large-scale liquefiers integrate several critical proprietary technologies developed and manufactured in-house:
- High-efficiency expansion turbines.
- Optimized heat exchangers for ultra-low temperatures.
- Advanced insulation cold boxes.
These components ensure exceptional reliability and low energy consumption, even for the most ambitious industrial projects.
Scaling for future global markets
Air Liquide’s portfolio is scaling rapidly to meet growing global demand. We are currently supplying the high-performance equipment for the largest hydrogen liquefaction plant in the world in South Korea, featuring a production capacity of 90 tonnes per day.
To support massive liquid hydrogen export projects, our engineers have already developed the next generation of liquefiers with capacities up to 150 tonnes per day in a single train. These solutions allow for the massification of production while significantly reducing operational and maintenance costs.
Revolutionizing hydrogen logistics: The 16-to-1 advantage
To enable the industrial scale-up of the energy transition, liquid hydrogen is the definitive solution for high-volume distribution. The liquid format radically streamlines the global supply chain: a single truck carrying 3.6 tonnes of liquid hydrogen is equivalent to 16 trucks of compressed gas (at 200 bar).
This massive reduction in transport traffic significantly lowers the carbon footprint of the delivery network. Drawing on decades of space-industry heritage, Air Liquide provides the large-scale infrastructure required to decarbonize maritime and aviation sectors. To further maximize efficiency, we have pioneered the Advanced Delivery System, an innovation that optimizes cryogenic transfer to high-capacity stations by drastically limiting evaporation losses (boil-off).
Frequently Asked Questions (FAQ)
Why is liquid hydrogen required for international energy export?
For intercontinental trade, shipping compressed gas is economically unviable due to its low volumetric density. Converting hydrogen into its liquid format shrinks its volume by 850 times, making it the only scalable method to maximize the energy payload of ocean-going vessels and safely transport mass energy across global supply chains.
What is the Air Liquide Advanced Delivery System?
It is a proprietary innovation that optimizes cryogenic transfer to high-capacity stations and ships, drastically reducing evaporation losses (boil-off) to ensure maximum efficiency during bulk transport.
Is liquid hydrogen pure enough for all industrial applications?
Yes. The liquefaction process naturally achieves an ultra-high level of gas purity, ensuring the liquid hydrogen meets the most stringent requirements for both heavy industry and high-performance fuel cell systems.
