New analysis from clean cold technology company Dearman has discovered that zero-emission transport refrigeration systems could cut overall engine pollution by up to 93% - having a major impact on overall air quality.

If poorly regulated, refrigeration systems on trucks that are powered by auxiliary diesel engines can emit up to six times the nitrogen oxide (NOx) and 29 times the particulate matter (PM) of a truck’s Euro6 propulsion engine.

Dearman has addressed this ever-pressing green issue with its own transport refrigeration system, which is powered by the expansion of liquid nitrogen (N2) and which crucially, doesn’t emit any pollutants associated with combustion.

The UK company revealed that by equipping a Euro6-standard 17-tonne rigid body truck with a zero-emission refrigeration system instead, overall engine emissions could be reduced by up to 93%, with NOx emissions slashed by up to 73%, as explained in the infographic below.

The technology is currently undergoing final closed-road testing ahead of commercial deployment in field trials expected later this year.

Toby Peters, CEO of the corporation, explained, “By increasingly moving over to zero-emission alternatives, there is an opportunity to have a major environmental impact without forcing companies to change the way they operate. It could be a small change that makes a big difference.”

In a press release, Dearman quoted a study which found that the environmental and health impacts of emissions of carbon dioxide (CO2), hydrofluorocarbons (HFCs), NOx and PM will impose an annual burden of more than €2.5bn in 2025 if not addressed.
