What is an e-turbo? What's a turbo doing in a hydrogen fuel cell powertrain?
Transport and energy journalist David James visits Laith Al-kazaz, Advanced Engineering Director at Cummins to learn about this technology, developed by a £20 million project to capture wasted energy and put it back into use.
Known as 'Trident', this project aimed to increase efficiency in hydrogen fuel cells through the development of an e-turbo, a vital component to help decarbonise heavy-duty vehicles.
The project has had wider impacts on Cummins’ conventional turbos, with projected savings of approximately 200 million tonnes of CO2 over the next 10 years.
Trident received £10 million in government grant funding through the Advanced Propulsion Centre UK.
