What we do

Climate-i is working to reduce the world’s most potent emissions: F-gases.

We help companies protect critical systems and prevent emissions through predictive monitoring of F-gas assets.

Our team is experienced in the development of AI/ML software, IoT systems and sensor hardware, allowing us to seamlessly integrate hardware and software as a service.

We are building technology to predict equipment failure, improve system reliability and efficiency and reduce the carbon footprint of important infrastructure. We are starting by tackling emissions of sulphur hexafluoride (SF6) from electricity grids.

What are F-gases?

Fluorinated gases (F-gases) are a family of chemicals that include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). They are synthetic and do not occur naturally in the environment in significant quantities.

Many HFCs were developed as refrigerants for air conditioning and refrigeration systems to replace ozone-depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) which are also F-gases. By contrast, SF6 is used primarily as an insulating gas in high-voltage electrical equipment while other F-gases have various industrial applications including in electronics and semiconductor manufacturing.

Why do F-gases matter?

Unfortunately, F-gases are extremely potent greenhouse gases. SF6 has the highest global warming potential of all – over 25,000 times more warming than CO2. Their potency means that while F-gases are typically used in small quantities they make an outsize contribution to climate change, contributing around 5% of CO2 equivalent emissions each year, surpassing global aviation.

Some F-gases, including most HFCs, are relatively short-lived once they are in the atmosphere, so curtailing their emissions can make a big difference to global warming within a short period of time. Others, like PFCs and SF6, last for thousands of years, so stopping emissions today reduces their impact far into the future.

In addition, some F-gases are classified as “PFAS”, per- and polyfluoroalkyl substances, also known as “forever chemcials” because of their persistence in the environment in soil and water. Concerns about the impact they have on human health have led some governments to restrict their use. You can read more about PFAS here.
