Since 2003, Osaka Gas has sold more than 56,000 co-generation products to residential customers. These products use internal combustion technology to generate up to 1 kilowatt of electricity with an electrical efficiency of 22.5%. In mid-2009, Osaka Gas began marketing a co-generation product based on PEM fuel cell technology, which can generate up to 0.75 kilowatts at an electrical efficiency of up to 35%. In contrast, Ceramic Fuel Cells’ BlueGen product can generate up to 2 kilowatts of electricity with a peak electrical efficiency of up to 60%.
Founded in 1905, Osaka Gas is one of the top seven gas companies in the world, with 2009 revenues of $13 billion and 19,000 staff. The company supplies natural gas to 6.9 million customers in Osaka and the surrounding region, representing 26% of all gas sold in Japan. Osaka Gas is developing into a multi-energy services provider of natural gas, electricity, LPG, district heating/cooling and other services.

About the size of a dishwasher, each BlueGen unit can produce enough electricity and heat to meet the annual requirements for power and hot water of the average Japanese home. BlueGen units can generate electricity at a peak electrical efficiency of 60%, which is 25% higher than other small-scale solid oxide fuel cell systems under test in Japan. When heat is recovered for hot water, total efficiency increases to 85%, twice as efficient as the current power grid. By generating power close to where it is used, Ceramic Fuel Cells’ products can meet the future demand for electricity without the need for huge investments in electricity transmission and distribution infrastructure.
