Operations of a Solid Oxide Fuel Cell (SOFC) Cogeneration System for Home Use
Commencing on November 28, 2005, Osaka Gas Co., Ltd. (President: Hirofumi Shibano) and Kyocera Corporation (President: Makoto Kawamura) will begin the first trial operations in Japan of a solid oxide fuel cell (SOFC*1) cogeneration system*2 in the 1kw class for home use installed in a joint research home (a residence unit housing a family of four) in the Next 21*3 , experimental housing complex owned by Osaka Gas.
The companies jointly commenced development of a 1kw class SOFC cogeneration system for home use in April 2004, and since then have undertaken the challenge of improving the operational power generation efficiency, reliability and specifications of products intended for commercial sale. To date, Osaka Gas has been evaluating test models containing performance improvements manufactured by Kyocera. As a result, the originally targeted power generation efficiency ratio exceeding 45% (AC generator output efficiency*4, LHV basis*5) has been achieved, due mainly to increased inverter efficiency, elimination of peripherals and reduction of electrical power consumption.
This represents the worlds highest level of power generation efficiency for a 1kw power generation system. Moreover, such rate exceeds the 40%*6 primary energy generation efficiency ratio of power supply systems incorporating large scale thermal power plants and power distribution grids by at least 5 points, which demonstrates the high level of energy savings featured by the system. The performance of the system with respect to startup, shutdown and load following capability has been satisfactorily confirmed.
The purpose of these trial operations of the SOFC cogeneration system for home use at an actual residence is to confirm system reliability, identify problems involved in the development of commercial products and to analyze technologies for introduction of the SOFC cogeneration system to multifamily housing. The energy savings effect and reduction of CO2 emission volume when used for production of electricity and heat in an average house will be evaluated as well.
The characteristics of a SOFC cogeneration system include power generation efficiency which occupies a comparatively higher portion of total energy efficiency, and it is accordingly expected to have economic merits in residences where demand for heat is less than demand for electric power. Such system also can store hot water at high temperatures meaning that the volume of stored hot water can be relatively small. Accordingly, the size of hot water tank can be compact, occupying minimal space. Such feature can make a home cogeneration system suitable not only for detached houses but also for individual units in multifamily housing where demand for heat is limited.
Both companies aim to launch products in the market sometime in fiscal March 2009 and will accelerate product development by undertaking these trial operations at an actual residence.
