Cummins: Spinning up E-Turbo innovation

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.
