Global liquid carbon dioxide production in 2025 is estimated at approximately 85 to 95 million tonnes, reflecting a tightly balanced and infrastructure-constrained segment of the industrial gases ecosystem. Supply growth remains incremental and closely linked to upstream availability from ammonia plants, hydrogen units, ethanol fermentation and natural gas processing facilities. Market conditions balance food and beverage, industrial, medical and emerging decarbonisation applications against episodic supply disruptions caused by plant turnarounds, feedstock outages and regulatory pressure on fossil-based sources. The global picture shows modest year-on-year growth with persistent regional tightness during peak demand periods.
Supply leadership is concentrated in regions with extensive ammonia, hydrogen, and bioethanol operations, supported by well-developed CO₂ capture, purification, and liquefaction infrastructure. North America remains a major producing region, driven by recovery from ethanol fermentation facilities and ammonia synthesis plants. Europe depends largely on CO₂ recovered from ammonia production, which creates structural supply risks during fertilizer plant outages. Asia-Pacific is adding capacity alongside fertilizer and fermentation sector growth, though availability remains uneven across countries. Latin America and Africa operate relatively small, captive recovery systems and rely on localized sources, resulting in recurring challenges around supply consistency.
Demand across regions continues to be underpinned by food, beverage, and industrial uses. Buyers prioritise high and consistent purity levels, dependable delivery timing, thermal stability throughout the supply chain, and assured availability during seasonal consumption peaks.
Key Questions Answered
Food-grade liquid CO₂ dominates global volumes because beverage carbonation, food preservation and cold-chain applications require high purity and uninterrupted supply.
Key Questions Answered
Ammonia and fermentation routes dominate global supply because they provide relatively concentrated CO₂ streams with established capture technology. Cost competitiveness depends on plant uptime, energy efficiency and proximity to end users.
Key Questions Answered
Food and beverage applications remain the largest end use because carbonation demand is stable and seasonally intensive, requiring high supply reliability.
Key Questions Answered
North America maintains the most diversified liquid CO₂ supply base driven by ethanol fermentation and ammonia production. However, regional imbalances still occur during peak summer demand.
Europe relies heavily on fertilizer-linked CO₂ recovery and remains vulnerable to plant shutdowns, creating periodic supply shortages for food and beverage sectors.
Asia Pacific shows expanding capacity linked to fertilizer growth and fermentation activity, but infrastructure gaps limit cross-border supply flexibility.
These regions operate smaller, often captive liquid CO₂ systems. Supply reliability depends on local plant uptime and limited storage buffers.
Key Questions Answered
Liquid CO₂ supply begins with capture from industrial processes, followed by purification, compression, liquefaction, storage and distribution in insulated bulk tanks or cylinders. Downstream buyers include beverage bottlers, food processors, industrial users and healthcare providers.
Energy consumption, plant uptime, storage capacity and logistics dominate cost structure. Trade remains highly regional due to transport constraints, making local supply resilience more important than global trade flows. Pricing reflects feedstock availability, seasonal demand intensity and emergency supply premiums.
Key Questions Answered
The liquid CO₂ ecosystem includes ammonia and hydrogen producers, ethanol plants, gas processors, CO₂ recovery specialists, bulk gas distributors and end-use industries. Producers with diversified feedstock sources, redundant capture units and strong distribution networks maintain competitive advantage.
Strategic themes include investment in fermentation-linked CO₂, improved storage capacity, energy-efficient liquefaction, integration with carbon capture initiatives and long-term supply contracts for food and beverage security.
