Honda and Climate Energy bring micro-CHP to market
Combined-heat-and-power (CHP) or cogeneration systems are becoming popular on a utility scale, because of their high efficiency compared to ordinary power plants that produce a lot of heat that gets lost (image, click to enlarge). Large-scale CHP is tied to the urban fabric of the site where electricity and heat are generated. In so-called 'district heating' concepts, the power plant delivers heat directly to end-users. CHP used in combination with biomass or biogas - already commonly found in Europe - makes for a very clean and efficient energy system.
However, the ultimate dream of energy engineers has been to find ways to scale down CHP systems in such a way that each household can have its own highly efficient power-station at home. Some progress has been made towards the development of such micro-CHP systems that can handle biomass (basically wood pellets). But now Honda Motor and Climate Energy announced they have started retail sales of 'freewatt', micro-CHP cogeneration system for homes that works on natural gas. Obviously, when biogas is used instead - an option becoming feasible where biogas is being fed into the main natural gas grid (as is being done on an ever larger scale in Europe) - then we are en route to a genuinely green revolution.
But let us have a look at the 'freewatt' micro-CHP system that will be for sale in the U.S. (image, click to enlarge). It is comprised of an MCHP cogeneration unit developed by Honda, which is paired with a furnace or boiler produced by Climate Energy. This system provides heat for the home with the added benefit of electricity production. The ultra-quiet MCHP unit produces 3.26 kilowatts of heat and 1.2 kilowatts of electric power. Further, it allows homeowners to reduce their utility bills and curb carbon dioxide emissions while improving overall energy efficiency and comfort.
In relation to energy costs, Climate Energy test data has shown that when the freewatt Micro-CHP system replaces a typical 80% efficiency home heating system, homeowners can realize an average of 30% in energy cost savings:
bioenergy :: biofuels :: energy :: sustainability :: CHP :: cogeneration :: natural gas :: biogas :: biomass :: energy efficiency ::
The freewatt system produces electric power as a by-product of its heating functionality. The electric power produced displaces electricity that consumers would otherwise purchase from the local electric utility, saving $500 to $1000 per year on their electric bill. An additional unique financial savings benefit of utilizing the freewatt system is realized through the process of net metering.
In states where legislated, net metering allows homeowners to literally sell unused electric power back to the power grid in their community, providing additional savings.
In addition, the system produces 30% less carbon dioxide emissions than a conventional heating system with electricity provided from the grid. This allows homeowners to take an active role in the effort to reduce greenhouse gases.
Comfort is enhanced due to the system's ability to provide constant and extremely quiet circulation of heated air. This produces more uniform and comfortable temperatures in the home without running noisy blowers at high speeds.
Initial sales of the heat and power units will be targeted at customers living in the Northeastern United States in conjunction with select local utility providers.
This is due to the cold climate and high heating demand in the region which allows the system to provide the greatest benefit. The freewatt Micro-CHP systems will only be available through certified, trained, and authorized Climate Energy installation professionals.
Climate Energy and Honda plan to gradually expand production and sales of the freewatt Micro-CHP system and plan to introduce the system to other cold weather climates in the U.S. in the future. The units will be assembled domestically in the United States with components supplied by both companies. Currently, a similar version of an MCHP system is retailed in Japan, with over 45,000 units sold to date since its introduction in 2003.
