This fourth-generation experimental unit is designed to provide fuel for a hydrogen-powered fuel cell vehicle, as well as heat and electricity for a home. The new system is more compact and efficient, with a lower operating cost than previous models, according to Honda.


The announcement coincided with the world debut of the new FCX Clarity hydrogen-powered fuel cell vehicle at the Los Angeles motor show.


The home energy station technology is designed to facilitate the broader adoption of zero-emissions fuel cell vehicles by developing a domestic refuelling system that makes efficient use of a home’s existing natural gas supply for production of hydrogen, while providing heat and electricity for an average-size home.


The latest unit can reduce both cost and carbon dioxide (CO2) emissions for the consumer. Compared to the average US home with grid-supplied electricity and a petol-powered car, a home using the home energy station to help produce heat and electricity and also to refuel a car can reduce CO2 emissions by an estimated 30% and energy costs by an estimated 50%.

“Honda is striving to address the need for a refuelling infrastructure for hydrogen fuel cell vehicles,” said Honda R&D Americas head Ben Knight. “The home energy station represents one promising solution to this issue, while offering the added benefit of heating and powering the home more efficiently.”


Working with technology partner Plug Power, Honda began operation of a home energy station in October 2003. The latest unit is 70% smaller, making it even more suitable for household installation. By combining gas purification and power generation components, overall size reduction and efficiency gains were achieved, while enabling it to switch from hydrogen refining to power generation when needed.
