DEC was formed in 2011 to develop and commercialise an innovative heat engine that uses liquid air (nitrogen) as a working fluid. The company's development strategy is to bring the "Dearman Liquid Air Engine" to market by working with consortia of partners who have relevant expertise to pair with DEC's core liquid air engine technology competencies.
Liquid Air Engine Commercial Vehicle Demonstration
A consortium of the Dearman Engine Company, MIRA (Motor Industry Research Association), Air Products and Loughborough University has won an IDP8 grant from the Technology Strategy Board to build and test a Dearman engine fitted in a commercial vehicle in 2014 (Q2, integration mule; Q4, full field trials). IDP8 is specifically to support the development and demonstration of disruptive technologies for low carbon vehicles that could achieve significant cuts in CO2 from road transport.
The project will demonstrate the Dearman engine on a refrigerated truck, providing zero emission Cooling and Power.
An Industrial Advisory Board representing fleet operators will advise the consortium partners and review the benefits of the technology to their businesses.
By validating all the key systems of the Dearman engine in a mobile environment, alongside filling
MIRA is proud to lead a project delivering the world's first demonstration of a liquid air engine in a commercial vehicle. Liquid air is an exciting new energy vector and has the potential to make a major contribute to the low carbon challenge facing the transport sector.

and other vehicle management procedures, this programme will support further applications for the technology such as waste heat recovery from internal combustion engines and zero-emission propulsion.
Waste Heat Recovery
Concurrent to the power and cooling engine field trials, the company aims to have a test-bed 30-50kW high efficiency Waste Heat Recovery engine - harnessing the waste heat from the radiator coolant loop - during 2014.
Dearman is also working with Ricardo and its other partners on ZEV prime mover applications.
As a prime-mover, the Dearman Liquid Air Engine offers advantages of zero emission, noncombustive, similar (or better) range to an EV, similar cost to an ICE, fast refuelling with a liquid (equal to petrol/diesel), and very favourable embedded carbon.
This application is highly relevant for multi-billion $ global on-and off-highway applications, including industrial (e.g. fork-lift trucks), mining, inland waterways applications, the built environment, as well as opportunities in emerging markets around urban vehicles (e.g tuk-tuks and quadricycles).
