Published by the Centre for Low Carbon Futures (CLCF), the report concludes that liquid air technologies could also significantly increase the efficiency of road vehicles, particularly in Britain’s fleets of buses, vans and refrigerated lorries.
The Dearman Engine is a piston engine that runs on liquid air, with a commercial demonstration engine is currently being built with Ricardo. Meanwhile, the Ricardo split-cycle engine is a highly efficient diesel design that uses liquid nitrogen to capture heat from its own exhaust. Liquid air technologies require no rare or expensive materials such as lithium or platinum.
