Dearman is a technology company delivering clean ‘cold and power’
Dearman technologies uniquely harness liquid nitrogen to deliver zero emission power and cooling.
Dearman is developing and demonstrating a portfolio of proprietary technologies, products and services, which deliver significant reductions in operating cost, fuel usage and emissions, all at low capital cost.
How society delivers clean and sustainable cold is a major issue, given the global challenges of food scarcity, changing demographics and growing energy demand.
Dearman, with its cutting-edge clean cold and power technologies, and world-class engineering expertise, is well-placed to make the world a cleaner and cooler place.
The Dearman Engine
At the heart of our technology portfolio is the Dearman engine, a novel piston engine powered by liquid nitrogen – that generates both cold and power from a single tank of ‘fuel’. It is efficient, low carbon, zero-emission, quiet and cost-effective, and reconciles the conflicting economic and environmental challenges posed by resource scarcity, poor air quality and climate change.
