The novel piston engine-based system, developed in partnership with Hubbard Products and Air Products, is in line for recognition in the ‘Innovation in Air Quality Technology’ category.
Toby Peters, founder and CEO of Dearman, explains that the engine – which uses liquid nitrogen expansion to deliver power and cooling – replaces conventional diesel-powered auxiliary transport refrigeration units.
Importantly, it can reduce the overall NOx emissions from a refrigerated vehicle by more than 70% and diesel particulate emissions by greater than 90%.
“Air quality is one of the great challenges that we face in the UK and around the world,” comments Peters.
“Diesel undoubtedly has a role to play for many years to come, but we must accept that it’s highly polluting and ensure that it’s only used where it’s most needed – and where it will do the least harm,” he continues.
“Using diesel to keep food cold in densely populated urban communities doesn't fit that bill.”
For Peters, the Dearman engine is about providing a high efficiency, cost effective and zero-emission alternative.
“There are lots of exciting air quality innovations being developed at the moment, and we know we face stiff competition, but we are looking forward to the awards and wish all the shortlisted companies the best of luck.”
