Transcritical CO₂ Market is forecasted to reach USD 156.66 billion by 2034, rising at a notable CAGR of 16.30%

Market Definition

The transcritical CO₂ market refers to the segment of the refrigeration and cooling industry that utilizes carbon dioxide (CO₂) as a natural refrigerant in transcritical systems, where CO₂ operates above its critical point for part of the refrigeration cycle. These systems are primarily used in commercial refrigeration, industrial cooling, and heat pumps, offering an eco-friendly alternative to traditional hydrofluorocarbon (HFC)-based systems. Transcritical CO₂ technology is valued for its low global warming potential (GWP), non-toxicity, non-flammability, and high energy efficiency, particularly in colder climates. The market is driven by increasing environmental regulations, a global shift toward sustainable refrigeration, and advancements in system design and performance.
