Dearman presents at IIR conference on sustainability and the cold chain

London, UK:  Dearman presented analysis to leading industry representatives, at the 4th IIR International Conference on Sustainability and the Cold Chain.

Dearman presented a paper Driving Clean Cold, which details the environmental impact of the growing transport refrigeration market and explores the implementation of zero-emission alternatives.

The paper builds on research predicting extremely rapid growth of demand for transport refrigeration. Upper estimates suggest there could be over 16 million such fridges in operation by 2025 – up from 2.1million today.

Largely driven by changing demographics in the Asia Pacific region and increased demand in the transport refrigeration market, this growth could have major global environmental consequences if demand is met with existing fossil fuelled technology.

Lead author of the paper, and lead analyst at Dearman, Etienne Teyssandier said: “In the UK, more than 90% of fresh produce relies on refrigerated transport, making it a vital part of the retail sector. With zero-emission alternatives available to operators, and infrastructure in place to support deployment, it is simply unnecessary to continue powering this refrigeration by burning diesel. Switching to zero-emission transport refrigeration presents real opportunity to improve air quality, reducing emissions of NOx and particulates, both in the UK and internationally.”

A diesel truck fridge can emit up to six times as much NOx and 29 times as much PM as a modern truck’s main engine. An increase in this disproportionate emission of pollutants would have a detrimental effect on the environment and the public’s health. A fleet of only 13,000 zero-emission TRUs would reduce NOx emissions by the same amount as taking 1.2 million diesel cars off the road – the UK’s fleet of diesel TRUs numbers more than 84,000.

Dearman’s research goes on to evaluate the potential reductions in all forms of pollution that could arise from mass adoption of novel, zero-emission, liquid air truck refirgertion systems. For example, research released by the company recently found that replacing a diesel driven fridge with a zero-emission alternative could reduce the vehicle’s overall emissions of NOx by more than 70%. In practice, switching from diesel to zero-emission technologies would result in savings of 16,000 tonnes of PM in China alone by 2025.

Dearman’s technology, based around the liquid nitrogen-powered Dearman Engine, is one such technology that could effect a positive change in the industry. The company’s zero-emission transport refrigeration system is currently preparing for certification ahead of commercial deployment this spring and extended trials later in the year.
