American Honda Motor Company and Massachusetts-based Climate Energy, LLC have collaborated in the first test installation of a micro-sized combined heat and power system (Micro-CHP system). At the Braintree, Mass., residence of Mr. Bernard Malin, the Climate Energy system is now using cogeneration technology with natural gas to provide residential heat more efficiently than ever before, given the added benefit of producing electric power.
Honda supplies its compact home-use cogeneration unit to Climate Energy, which in turn, combines it with a furnace or boiler as a supplemental system to conventional space heating and electric power in new and existing homes, while delivering ultra-quiet operation.
The complete Climate Energy Micro-CHP system, powered by the Honda MCHP unit, results in more than 85 percent efficiency in converting fuel energy into useful heat and electric power. The system also is expected to yield a 30 percent reduction in carbon dioxide emissions as compared with conventional heating appliances and grid supplied electricity.
In conjunction with technology partner Plug Power Inc., Honda had developed the latest version of its MCHP unit, the Home Energy Station III. The system is designed to work in a home-based refueling environment using a natural gas reformer to produce a sufficient amount of hydrogen to power a fuel cell vehicle, such as the Honda FCX, for daily operation while providing electricity for an average-sized household. During normal operation the unit generates up to three kilowatts of thermal output per hour and one kilowatt of electricity. The unit is also able to function as a backup power generation system during power outages by using the hydrogen in the storage tank to power the internal fuel cell, providing as much as 5 kilowatts of electrical power to the home in normal and emergency conditions.
