Sainsbury’s teste l’azote liquide pour refroidir ses camions.

L’enseigne britannique de supermarchés expérimente une nouvelle technologie de froid embarqué à l’azote liquide. (En anglais.)
UK supermarket chain Sainsbury’s is currently testing a refrigerated delivery truck cooled by a liquid nitrogen powered engine.
Traditionally many refrigerated trucks require two diesel engines, one to power the vehicle and one for the refrigeration unit. It is the latter which is here replaced by a zero-emission cooling unit supplied by Dearman.
The new system harnesses the rapid expansion of liquid nitrogen to deliver zero-emission power and cooling. During the three-month trial, the vehicle is expected to save up to 1.6 tonnes of CO2 emissions; the equivalent of driving over 14,500 km in a modern family car.
The trial is also expected to save 37 kg of nitrogen oxides and 2 kg of particulate matter, compared to a similar system. Assessment of the success of the trial will be considered, along with operational cost on any potential for roll out of the technology.
