Combined Heat and Power (CHP) is not a new idea to the UK. Woking for example, has a large district heating network which makes considerable carbon savings and the Immingham plant on the Humber is a large industrial example. Yet when one compares the UK to Sweden, UK CHP seems very underdeveloped in comparison. Here we would like to discuss just what makes Swedish CHP so great and what the future holds in the UK for the technology.
We won't cover the technical aspects to CHP cogeneration here, as just an introduction is needed. The principle is simple however; whether on a micro scale or on an industrial scale, power production and industrial processes usually create a lot of heat, which is wasted ''potential'' energy. CHP cogeneration aims to take this waste heat and make it useful, increasing the efficiency of the installation. Often this will mean piping the heat to nearby buildings to be used for domestic, industrial heating, or even, additionally [by the use of Absorption Chillers] chilled water for air conditioning! Known as TRI-Generation
