Residential Co-Generation System Proven Effective at Aichi Expo 2005

Keywords: Energy Conservation Environmental Technology University / Research institute 

Residential fuel cell co-generation systems were proven to be effective in reducing energy consumption and carbon dioxide (CO2) emissions during the first 5 months of a demonstration test conducted at the World Exposition 2005 held in Aichi, Japan. This was the conclusion announced in an interim report by the Urban Renaissance Agency, Toyota Motor Corp., Aisin Seiki Co. and Toho Gas Co. on August 18, 2005.

Using two of these co-generation units, they conducted a demonstration test of a microgrid system to supply electricity and heat to four apartments at the accommodations of official participants at the Aichi Expo. According to the interim findings, the microgrid system was able to reduce primary energy consumption by about 13 percent and CO2 emissions by about 23 percent compared to a conventional system that supplies electricity and gas separately.

The test also showed that the microgrid system was able to reduce CO2 emissions by about 6 percent and energy consumption by more than 8 percent compared with a system with a separate residential fuel cell unit in each home. The four entities said in the interim report that they would seek further reduction of energy consumption and CO2 emissions in the second half of the test by adjusting the operation of the system match to the actual amount of demand for hot water.
