F-gas phase down: keeping data centres cool with Aggreko

Data centres play a crucial role in our digital society, supporting critical technologies such as AI, 5G, and cloud computing. However, their environmental impact is increasingly under scrutiny, one aspect being the use of fluorinated gases (F-gases).

In the data centre industry, as in many other energy-intensive sectors, F-gases are widely used due to their efficiency and reliability. They remain essential to ensure the safe, stable, and energy-efficient operation of vital infrastructure, including high-voltage (HV) and medium-voltage (MV) electrical switchgear (SF₆), cooling systems (HFC refrigerants), and fire suppression systems (HFC gas and foams). By preventing overheating, reducing fire risks, and ensuring uninterrupted power supply, these gases help data centres avoid costly downtime.

At Aggreko, we understand operational priorities and the importance of maintaining continuous, reliable cooling. Our solutions are designed specifically to help data centres navigate the complex transition away from high-GWP refrigerants smoothly, keeping their operations stable and compliant as regulations evolve.

Understanding the impact of new F-gas regulations

The European Union has implemented stringent regulations (EU Regulation 517/2014) aimed at phasing out F-gases by 2050 due to their high Global Warming Potential (GWP). While fluorinated gases do not deplete the ozone layer like CFCs, their environmental impact is severe, with their GWP being thousands of times higher than CO₂. When released into the atmosphere, F-gases can persist for millennia, exacerbating climate change. To mitigate this, recent regulations mandate a gradual reduction in F-gas use, encouraging the adoption of more environmentally friendly alternatives.

Key measures include:

• Phase down of high-GWP refrigerants: The EU aims to reduce F-gas sales by nearly 95% by 2030, compared to 2015 levels. Refrigerants with high GWP will be banned from use in new equipment, with exemptions for certain low-temperature applications.
• Tightened restrictions on existing equipment: As of January 2025, refrigeration systems containing F-gases with a GWP above 2,500 will no longer be allowed to be serviced or recharged, creating a challenge for legacy infrastructures.
• Enhanced leak detection and maintenance requirements: Stricter regulations now require companies to install leak detectors and adhere to more frequent inspections. Failure to comply may result in fines. These measures aim to minimise harmful emissions and improve the overall sustainability of refrigeration systems.
• These changes not only affect equipment manufacturers and refrigeration operators but also require businesses to adapt to a rapidly evolving regulatory landscape focused on environmental responsibility.
