Dearman is looking to create an additional 30 – 40 jobs with roles including engineering, supply chain management, customer engagement, and after sales services. http://edition.cnn.com/2012/12/07/tech/dearman-liquid-air-storage/ This means the Dearman engine can be combined with a diesel engine or hydrogen fuel cell to form a 'heat hybrid', where waste heat and cold are exchanged between the engines to increase the efficiency of both and reduce fuel consumption. It was invented by Peter Dearman, a classic British 'garden shed' inventor, and is being developed by the Dearman Engine Company (DEC) to perform a variety of roles. The Dearman Engine, is a novel piston engine, powered by the expansion of liquid air, whose exhaust is clean cold air. In developing and emerging markets we are going to have about 3 billion new middle classes over the next 10-15 years. We have invested £2m through our growing places fund.
Dearman: technology firm drives a cold and power revolution.

Dearman is developing a range of technologies that use a novel piston engine powered by liquid air or liquid nitrogen to deliver zero-emission cold and power. Before the nitrogen gets to the engine, however, it has absorbed the heat of the refrigerated compartment through a heat exchanger. Dearman has worked on the Sainsbury’s trial with Hubbard Products, Dawsonrentals and Air Products.
That’s the biggest market opportunity for Dearman today. The first commercial deployment of Dearman’s zero-emission transport refrigeration system is a significant milestone for the company, for our technology and for our vision to make the world a cleaner, cooler place. It has recently moved into a new home in Croydon. Cryogenic expansion engines have existed for over a century, but the Dearman engine is novel because it uses a heat exchange fuid (made of water and glycol – just like conventional radiator fuid) to promote rapid and efficient re-gasification inside the engine cylinder. We would like to show you a description here but the site won’t allow us. Dearman is developing the technology to reduce emissions caused by traditional fuel sources and aims to address the issue of air quality.

Chief executive and founder of Dearman Toby Peters said: Sainsbury’s is demonstrating real leadership by embracing cutting-edge British engineering that delivers performance alongside positive environmental impact. You’ve accepted all cookies. Up to 40% of food in India and Asia is lost post-harvest before it gets to market because there is no cold chain. It is estimated that if all of London’s truck refrigeration was zero emission, the reduction in particulate emissions would be the same as taking more than 300,000 new diesel cars off the road. It is also being developed for use in back-up power systems for buildings and for more fuel efficient vehicle engines. Diamond's in house quality control saved expense and time of customer checking procedure and ensured Dearman Engine Company were able to pitch to potential investors and shareholders. Debugging of design at Diamond allowed a functional engine to be produced at the first attempt and cost and time savings to be made because of no need for multiple prototypes or engineers to redesign the concept.
