Personalized energy systems for heating, cooling, and powering cars
September 2, 2010
MIT researchers have developed a new concept of personalized energy systems, in which individual homes and small businesses produce their own energy for heating, cooling and powering cars.
“Our goal is to make each home its own power station,” said study leader Daniel Nocera, Ph.D of MIT. “We’re working toward development of ‘personalized’ energy units that can be manufactured, distributed and installed inexpensively. There certainly are major obstacles to be overcome — existing fuel cells and solar cells must be improved, for instance. Nevertheless, one can envision villages in India and Africa not long from now purchasing an affordable basic system.”
Such a system would consist of rooftop solar energy panels to produce electricity for heating, cooking, lighting, and to charge the batteries on the homeowners’ electric cars. Surplus electricity would go to an “electrolyzer,” a device that breaks down ordinary water into its two components, hydrogen and oxygen. Both would be stored in tanks. At night, when the solar panels cease production, the system would shift gears, feeding the stored hydrogen and oxygen into a fuel cell that produces electricity (and clean drinking water as a byproduct). Such a system would produce clean electricity 24 hours a day, seven days a week.
