LONDON: June 22, 2016. UK retailer Sainsbury’s has become the first company in the world to trial a refrigerated truck cooled by a liquid nitrogen-powered engine that eliminates all related emissions.

Sainsburys truckDesigned by technology specialist Dearman, the zero-emission unit replaces a traditional diesel engine and will save up to 1.6 tonnes of CO2 compared to a similar system during the three-month trial.

Many refrigerated trucks require two diesel engines, one to power the vehicle and one for the refrigeration unit. By replacing the latter, Dearman believes it’s a more sustainable solution that will be widely adopted in Britain.

Commenting on the trial, Sainsbury’s head of Sustainability Paul Crewe said: “As one of Britain’s biggest retailers we really recognize the importance of reducing emissions, which is why we’re working hard to cut carbon emissions by 30 percent between 2005 and 2020. This trial with Dearman is just one of the innovations we’ve introduced to help us towards this goal. Their zero-emission system is really exciting, to be running a liquid air engine quite literally means our cooling is running on thin air.”

In addition to being a cleaner method of refrigeration, liquid nitrogen is non-flammable and already transported on the UK’s road network by supplier Air Products.

Dearman’s founder and CEO Toby Peters added: “Sainsbury’s is demonstrating real leadership by embracing cutting-edge British engineering that delivers performance alongside positive environmental impact.”
