Sainsbury’s has reported that it has become “the first company in the world” to introduce a refrigerated delivery truck cooled by a liquid nitrogen powered engine that will “eliminate all emissions associated with refrigeration”. The grocer will evaluate the truck during the course of a three-month trial. It will operate from Sainsbury’s Waltham Point depot, delivering chilled goods to stores in the London area.
According to Sainsbury’s: “Based on the revolutionary British invention, the Dearman Engine, the new system harnesses the rapid expansion of liquid nitrogen to deliver zero-emission power and cooling.
“Traditionally many refrigerated trucks require two diesel engines, one to power the vehicle and one for the refrigeration unit. By replacing the latter, Dearman believes that a more sustainable solution for refrigeration may soon be widely adopted on Britain’s roads.”
