UK supermarket chain Sainsbury’s has become the first company in the world to introduce a refrigerated delivery lorry cooled by a liquid nitrogen-powered engine. The technology, which is being deployed during a three-month trial, is expected to eliminate emissions associated with refrigeration.

Developed by UK firm Dearman Engine, the cooling unit replaces the traditional diesel engine used to chill the vehicle. Based on technology invented by self-taught UK engineer Peter Dearman, the Dearman engine harnesses the rapid expansion of liquid nitrogen to deliver zero-emission power and cooling.
