Natural Refrigerants Market

The regulatory phase-down of high-global-warming-potential (GWP) man-made refrigerants is another factor driving the growth of natural refrigerants. The strict measures have been taken by governments and regulatory bodies to limit the release of hydrofluorocarbons (HFCs) and promote green cooling solutions. The EU’s F-Gas Regulation (EU) 2024/573 will further tighten quota restrictions on HFCs and impose GWP constraints on refrigerants used in newly installed equipment, while the American Innovation and Manufacturing (AIM) Act aims to reduce HFC production and consumption by 85% by 2036. Such regulatory activities are promoting the transition from high-GWP refrigerants to natural refrigerants like CO2, ammonia, and hydrocarbons among refrigerating equipment manufacturers, retailers, and industrial users. Demand for natural refrigerant-based equipment is expected to increase as companies align with changing environmental standards and regulations.

High upfront capital expenditure and retrofitting costs are another major barrier to adopting natural refrigerant-based refrigeration systems. Switching from traditional HFC-based machines to those that use natural refrigerants, especially CO2 transcritical machines, will require special compressors, high-pressure-rated parts, and specialized controls. All of these increase the costs of purchasing the new equipment and installing them on the system. In addition, retrofitting will also require changes to the piping system, the heat-rejection system, and other safety systems. This will raise the total cost of performing the retrofits, thereby causing smaller retailers, food service providers, and industries that have small capital to delay their investment on natural refrigerants.

Growth in cold chain infrastructure in developing nations creates substantial business opportunities for natural refrigerants. Investment in cold storage facilities, food processing plants, distribution centers, and refrigerated transport is driven by urbanization, higher disposable incomes, food security needs, and the rise of online grocery deliveries in countries such as China, India, and across Southeast Asia. Establishing refrigeration infrastructure enables equipment manufacturers and end users to install natural refrigerant technology during the design and construction of the facility, making retrofitting less expensive. Several refrigerant systems may be considered, depending on the application’s needs, operating conditions, and regulations. Moreover, government efforts to upgrade food chains and reduce post-harvest losses may encourage investment in temperature-controlled distribution and storage. As food processing and logistics capacities in emerging economies grow, there will be opportunities to install natural refrigerant systems in new facilities being built.

The performance constraints associated with hot climate make natural refrigerant solutions such as carbon dioxide (CO2) transcritical refrigeration technology technologically difficult to implement. In hot ambient environments, CO2 systems tend to operate above their critical point, leading to elevated gas cooler discharge temperature and pressures. In addition, energy requirements for operation of the refrigeration cycle will be increased. These effects can lead to reduced efficiency of the system in operation in case of hot environmental temperatures, thus affecting operating costs in areas such as the Middle East, some parts of India, and southern part of the United States. In order to deal with these challenges, designers of the system might choose to integrate technologies such as parallel compression, ejector, adiabatic gas cooler, and control system among others into their designs. This integration of different components in the system leads to increased complexity, capital cost, and maintenance needs.
