The Japanese electronics giant inaugurated a 200-kilowatt hydrogen fuel cell for its campus . The fuel cell which sits in the parking lot and looks like a pair of giant green dumpsters provides two types of energy to the facility. First, a unit heats methane with steam to create hydrogen. The hydrogen is passed through a proton exchange membrane (PEM). The electricity produced by the reaction with the PEM runs lights, computers and other equipment.

The hot water from the methane-hydrogen reaction is cycled through the building to create heat. More waste heat could be recaptured from the PEM unit, but the water is too hot for Fujitsu’s internal systems.


The heat harvested from the reactions required to turn hydrogen into electricity will be used by Fujitsu in the buildings too. Right now, the fuel cell system is 50 percent efficient. That puts it on par with conventional power plants with conventional systems, over half of the power gets lost in transmission lines or as waste heat before it gets to your house. By capturing more heat, the efficiency of the fuel cell can be raised to 85 percent.
