Hydrogen is a better source of energy than you think, according to Fujitsu. The Japanese electronics giant inaugurated a 200-kilowatt hydrogen fuel cell from UTC on Friday that will provide electricity as well as heat to the buildings on its campus here.

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. The electricity produced by the reaction with the PEM runs lights, computers and other equipment.
