“The impact of adopting zero-emission transport refrigeration units (TRUs) would be huge.” That’s the message that clean cold technology company Dearman has projected in the fight to clean up emissions from the UK’s transport sector.

The environmental impact of unregulated TRUs has been thrust back into the spotlight after Members of Parliament (MPs) encouraged ministers to take further action on diesel-powered trucks during a recent House of Commons debate.

At the discussion, Andrew Selous, MP for South West Bedfordshire, outlined that tackling highly polluting and unregulated TRUs is the first step towards helping combat climate change, creating new industries, responding to the challenges surrounding energy security and helping reduce the overall cost of driving.

Dearman’s revolutionary engine uses uses the expansion of either liquid air or liquid nitrogen to provide zero-emission power and cooling.

UK-based business Dearman has developed a zero-emission TRU which is currently undergoing advanced trials – leaving it well-placed to deliver this solution on such a monumental scale.

Dearman’s novel piston engine uses the expansion of either liquid air or liquid nitrogen to provide zero-emission power and cooling.

The only emission is air or nitrogen, with emissions of nitrogen oxide (NOx), carbon dioxide (CO2) or particulate matter completely eradictaed, unlike its conventional diesel transport counterpart, which are lightly regulated and can emit up to 29 times as much particulate matter and as much NOx as a modern truck engine.

Sainsbury’s became the first company in the world to introduce a refrigerated delivery truck, powered by the revolutionary Dearman engine, in June 2016, which saved approximately 1.6 tonnes of CO2 during its three-month trial. The technology has also won several respected awards in its field.

If the 84,000 TRUs that are currently in operation on UK roads were to become zero-emission, potentially by adopting Dearman’s technology, it would equate to taking five and half million Euro6 diesel cars out of action. 

In Focus…Environmental Technologies

Michael Ayres, Dearman’s Deputy Chief Executive, highlighted, “There are growing calls for tighter regulation of transport refrigeration units, and this means that the industry needs to start preparing.”

“The impact of adopting zero-emission TRUs would be huge. Ministers are taking the right steps to improve Britain’s air quality, such as through the proposed Clean Air Zones, and Dearman look forward to showing the clear potential of our technology to help meet this vital objective.”

A study released in 2015 showed that pollutions from transport refrigeration could cost EU countries approximately €22bn ($24.7bn) over the next decade, with the EU refrigerated road vehicle fleet set to grow to almost 1.2 million by 2025.
