Micro Energy Systems for the 21st Century IMechE seminar 6th June 2002 Micro Combined Heat & Power; Jeremy Harrison, EA Technology Micro Combined Heat & Power (mCHP) has substantial economic and environmental potential. Ultimately it may be installed in over 12 million UK homes and provide an installed generation capacity of a similar order of magnitude to the nuclear industry. A range of micro CHP technologies are approaching commercial launch. It is anticipated that Stirling engine based units will become available in 2003, with fuel cells perhaps five years later. This paper considers the characteristics of the leading Stirling engines (and other prime mover technologies) and their potential applications in the domestic sector, with particular reference to the WhisperTech WG800 currently undergoing its second year of UK field trials. The paper will also outline challenges facing such technologies, including interface with the home energy system and the electricity distribution network. |
