National Institute for Land and Infrastructure Management conducted an experiment to supply hydrogen to household fuel batteries using the public utility conduit. This experiment is part of the efforts to build a low carbon society because supplying hydrogen using urban infrastructure is vital to realize a society that uses hydrogen as an energy source.
The research agency installed conduit pipes for about 250 m in the public utility conduit of the nearby city. In the experiment, it supplied hydrogen in hydrogen cylinders to the fuel batteries in the simulated house through the public utility conduit. Generated electricity and heat were used to illuminate the lights, play the DVD players, and operate the hot-water heater. Currently, city gas is supplied to household fuel batteries. A fuel battery can be downsized considerably and higly efficient if it can utilize hydrogen directly.
