According to a report by the Centre for Low Carbon Futures (CLCF), liquid air could reduce diesel consumption in buses or freight vehicles by 25 per cent using a liquid air Dearman engine/diesel hybrid.
The report says that in all but one scenario, per-kilometre costs for a car running on liquid air would be lower than for a petrol car with average UK fuel economy, and while electric vehicles such as the Nissan Leaf have lower running costs, the capital costs of a liquid air car would be around those of a car with an internal combustion engine, with the potential to be lower in the long-term, due to the fact that the engine can be produced from lighter materials.
