Cryogenic Air Separation Unit Market Size
The global cryogenic air separation unit market was valued at USD 4.2 billion in 2024 and is estimated to reach the value of USD 6.7 billion by 2034, growing at a CAGR of 4.7% from 2025 to 2034. Rising demand from steel, chemical, and manufacturing industries drives the market growth. Rapid industrial growth in developing countries is increasing the need for gases, including oxygen and nitrogen, leading to more investments in facilities that separate these gases from the air to support production growth.

Challenges
In citation, in 2024, China continued to be the world's largest steel producer, creating 1,005.1 million tons of crude steel, which is more than half of the global production. The process of making steel using a basic oxygen furnace uses about 55 cubic meters of oxygen for each ton of steel. This means they need over 55 billion cubic meters of oxygen annually, driving Chinese steel mills to place orders for new large-scale cryogenic air separation units (ASUs) to secure a stable, high-purity oxygen supply.
The shift to clean energy solutions, including hydrogen fuel and liquefied natural gas, is increasing the need for specialized cooling units. These technologies rely on very pure gases, leading energy companies to adopt efficient systems to separate air for sustainable production and storage. For instance, in 2024, the UK government provided up to USD 40 million in funding for the HyNet low-carbon hydrogen project in North-West England. A major part of this project is installing a unit that produces 200 tons per day to supply oxygen for blue hydrogen production, aiming to have the hub operational by 2026.
The COVID-19 pandemic has pointed out the need for reliable medical oxygen supplies in healthcare facilities around the world. As populations age and healthcare facilities expand, more systems are being installed to provide essential gases continuously. India's Ministry of Health & Family Welfare has increased its budget by 14% for 2024–25 to improve medical oxygen infrastructure. This includes storage and delivery systems in hospitals and community health centres across the country.
Companies are upgrading old systems to eco-friendly, high-capacity models, boosting market growth, meeting stricter environmental rules, and improving scalability across various industries. For instance, in 2024, the European Commission announced USD 4.1 billion in funding for projects aimed at reducing carbon emissions. One such project is GeZero in Germany, which will build a 2nd-generation oxyfuel cement kiln integrated with a new cryogenic ASU, a CO₂ liquefaction unit, and rail-loading station.
President Trump’s import tariffs in April 2025, with higher rates for select countries, raise costs for critical components including specialty steel, compressors, and rare-earth metals used in cryogenic units. Manufacturers may absorb expenses or hike prices, slowing industrial adoption in sectors including healthcare and steel. However, tariffs could spur U.S. production of air separation technologies, incentivizing domestic suppliers to innovate cost-efficient alternatives. Market investments may stall amid trade policy volatility, delaying upgrades or expansions until supply chains stabilize.
Cryogenic Air Separation Unit Market Trends
Industries are increasingly favoring small, adaptable cooling units for their flexibility and cost-effectiveness. These systems are perfect for remote areas and small operations, as they cut down installation time and expenses while meeting varied gas needs in fields including healthcare and electronics manufacturing. For instance, in 2024, the European Commission approved the IPCEI Hy2 Infra project, allocating USD 7.8 billion of public funding for modular cryogenic ASUs across seven Member States to scale up hydrogen infrastructure.
The combination of the IoT and AI is transforming cryogenic unit operations by using smart sensors for real-time monitoring, predicting maintenance needs, and managing energy, which reduces downtime and operational costs. Automation improves safety and accuracy in gas production, making it appealing to technology-focused industries. For instance, in 2024, the U.S. Department of Energy announced up to USD 36.8 million in funding for fiscal year 2025 to support digital twin technology and AI-driven predictive maintenance for cryogenic air separation units.
A growing emphasis on energy-efficient designs is aiding reducing carbon emissions and minimizing environmental impact in the gas production industry. Companies are using renewable energy and recycling waste heat to align with global climate goals. These eco-friendly innovations are appealing to industries aiming to comply with stricter environmental rules. For instance, in 2024, the EU Innovation Fund awarded USD 22.7 million to Austria's H2FUTURE project for renewable-powered air separation units that recover waste heat at the Voestalpine steel plant in Linz.
Rapid industrial growth in the developing regions is increasing the need for systems that separate gases at extremely low temperatures. The rise in building projects, along with growing healthcare and electronics industries, is leading to more investments to ensure a steady supply of gases for manufacturing and medical use. For instance, in 2024, Ghana's national plan for surgery and anaesthesia highlighted the need to install oxygen plants in all 16 regional hospitals to ensure a reliable supply of medical gases.
