CE Power, the hybrid bus capable of running on both diesel and liquid nitrogen has finished its trials. The bus has been built by engineers of HORIBA MIRA as a part of an Innovate UK consortium. The bus features the zero-emission Dearman Engine which is powered by liquid nitrogen resulting in a greater efficiency and lower tail pipe emissions. Led by Dearman, the partners for the Innovate UK consortium include Air Products, Cenex, Coventry University, HORIBA MIRA, Manufacturing Technology Centre, Productiv Ltd, and TRL (the Transport Research Laboratory). “The Dearman Engine has the potential to significantly improve the efficiency of both buses and HGVs, reducing fuel consumption and cutting pollution. Crucially it can provide a cost effective alternative to other emerging zero emission technologies, whose environmental performance if often offset by complexity and cost. This successful trial could be the first step towards rolling out a British innovation to the streets of the UK and around the world,” said David Sanders, Commercial Director at Dearman.
The availability of liquid enitrogen locally and with refueling only taking a few minutes, this alternate can soon give a tough competition to electric counterparts. Martin Watkinson, Technical Lead on the project at HORIBA MIRA said,”The hybrid nature of CE Power demanded a sleek systems integration process. Our engineers worked to ensure the liquid nitrogen system operates seamlessly and safely with the diesel engine, in addition to carrying out the whole vehicle thermodynamics modelling and the overall vehicle control and testing. The completion of these trials paves the way for the use of liquid nitrogen more widely in the automotive sector, and takes the UK one step closer to stamping out harmful emissions for good.”
