Combined Heat and Power (CHP) systems generate electrical power and heat simultaneously. There are three main technologies utilised to provide CHP systems - External combustion, Internal combustion and Fuel Cells. External combustion Central to the generation of electricity is the Stirling engine. A Stirling engine operates by being heated externally and so is described as an external combustion engine (ECE). Fuel Cells A fuel cell is an electrochemical cell that converts an input fuel into a number of outputs - an electrical current, heat and waste water or carbon dioxide. The primary function of a fuel cell is usually generating…
