A home hydrogen generating station that also makes heat and electricity

Honda, in conjunction with Plug Power, is developing a home based hydrogen pump station that produces hydrogen fuel for it's 2008 FCX fuel-cell car.

HES III uses natural gas as its feedstock, and is able to supply a sufficient amount of hydrogen to power a fuel cell vehicle for daily operation while providing 5 kW of electricity for a household as well as heat. It's hard to quantify the cost of home hydrogen production over using gasoline, because the by-products of hydrogen production can be used to trim other household costs. However, placing a further demand on the natural gas supply may drive up price of natural gas in peak demand cycles.
