Electricity grids around the world are being stretched by increasing demand, the retirement of older power stations and the growing use of intermittent renewable generation.
The capacity to meet the very highest demand peaks, has typically been provided by a fleet of distributed diesel generators. These are used to generate backup power in the event of a power cut; reduce consumption of grid electricity when power is most expensive; and earn revenue by providing reserve capacity to network operators. But diesel gensets are highly polluting and now being used increasingly often.
Dearman technology can provide an efficient, zero-emission alternative.

Dearman is developing a genset based on the Dearman engine, which will perform the same functions as a diesel system, including providing emergency backup power, reducing the owner’s energy costs and providing reserve services to the grid. What’s more, the Dearman genset would provide ‘free’ cooling, making it particularly advantageous for applications such as supermarkets and data centres, which require extensive cooling.
The Dearman genset is based upon the Dearman engine, utilising the expansion of liquid nitrogen to provide power, while the gas can be used directly in a heat exchanger to provide cooling to the building or its essential services.
