Dearman won the Innovation in Air Quality Technology category at the National Air Quality Awards.
Dearman received the award jointly with Leeds City Council after both parties worked together to trial a zero emission transport refrigeration unit (TRU) in the city and assess the impact of diesel TRUs on air quality.
Dearman is working with Marks & Spencer as the retailer seeks to reduce carbon dioxide (CO2) emissions from its chilled deliveries.
Dearman’s liquid nitrogen-powered engine is zero emission. The technology will replace diesel-powered secondary engines used to power transport refrigeration units (TRUs), which are used to keep food cold on the road.
