H Power Corp. has signed a third joint study agreement with Osaka Gas Co., Ltd., a natural gas utility serving more than 6,000,000 customers in the Kansai area of Japan.CLIFTON, New Jersey, June 28, 2002 [SolarAccess.com] The agreement calls for the delivery of eight 500 W proton exchange membrane (PEM) residential cogeneration fuel cell systems for in-house and field beta testing for the Japanese residential market. H Power has completed deliveries of the first generation systems for alpha testing under a previously announced agreement between H Power, Mitsui &Co., Ltd. (H Power’s marketing partner in Japan), and Osaka Gas. The 500 W system combines H Power’s proprietary fuel cell stack with Osaka Gas’ proprietary steam reformer. The system provides primary power and hot water for a residence, and can provide power at either 250 W or 500 W. In addition to operating at a constant output, it can also function in a load-following mode, in which the unit reacts continuously to changes in a residence’s power and heating requirements. The unit is connected to the grid, and is capable of automatic start-up and shutdown. Osaka Gas has been alpha testing an earlier version of the system since January 2002. The next-generation system includes design improvements based upon data and feedback from the alpha tests. H Power will deliver two units to Osaka Gas by fourth calendar quarter of 2002, with the remainder of the units being shipped by first calendar quarter of 2003. In addition, the companies agreed to examine ways to expand the presence of these next-generation units both within and outside of Japan.
