Our global transport system is going through its biggest transition in decades.

Climate change and increasingly stringent air quality regulations are pushing the automotive industry to build cleaner engines and use new fuel sources, such as hydrogen fuel cells.

That’s where we come in. 


Cleaner air for all

Today, our emission control technologies are used in hundreds of millions of cars, buses and trucks around the world, helping to remove millions of tonnes of harmful pollutants, like nitrogen oxides and particulates, produced by gasoline and diesel engines. The end result is fewer harmful emissions from vehicles and cleaner air for everyone.

Despite a growing number of government deadlines to phase out petrol and diesel vehicles, we’re not going to see the traditional combustion engine disappear overnight. So, we’ll continue to innovate and improve these technologies to meet new emissions legislation and keep people moving in the cleanest way possible while the transition towards battery and fuel cell vehicles takes place. 


The clean power of hydrogen

Our technology is central to this transition. For decades we’ve been using our knowledge of metals chemistry and electrochemistry to design and make membrane electrode assemblies and catalyst coated membranes that are the crucial components at the heart of a fuel cell. Our very first fuel cell technologies even helped power the US space programme in the 1960s. Today, our focus is firmly back on Earth and our fuel cell technologies are helping vehicles run on the clean power of hydrogen.
