Liquid-nitrogen engine could be an alternative to batteries

A design for a liquid-nitrogen-powered vehicle engine could provide an alternative to batteries and fuel cells following a planned feasibility study.

The engine, which is driven by the pressure created as liquid nitrogen (LN2) returns to its gas form, could provide a way of powering a vehicle without producing carbon-dioxide tailpipe emissions but with a longer range and faster refuelling than a battery.
