Scientists in Belgium have invented a solar panel that produces hydrogen as a source of fuel to heat homes, according to www.inhabitat.com. Using moisture in the atmosphere, the solar panel converts sunlight into hydrogen gas, producing about 250 liters of gas per day.
Led by Professor Johan Martens, the team of scientists have been developing the hydrogen solar panel during the past 10 years. They originally only were able to produce small quantities of hydrogen gas; however, the gas bubbles now are visible the moment the panel is rolled out under the sun.
"It's actually a unique combination of physics and chemistry," Martens says. "Over an entire year, the panel produces an average of 250 liters per day, which is a world record."
Martens estimates 20 solar panels could provide enough energy and electricity to heat a home and have some to spare for the following year.
Although the team is not yet ready to build the panels for commercial use, it is preparing for a trial run at a home in Flanders, Belgium. If the tests are successful, the scientists plan to expand their trials to an entire neighborhood.
Hydrogen is an extremely combustible gas and can be dangerous if not handled correctly. The scientists say although the general public may have some concerns regarding hydrogen as a heating source, the gas carries the same risks associated with natural gas. Hydrogen produced by the solar panels is stored in an oil tank installed near the home.
The technology is viewed as promising, with the potential to produce zero carbon emissions; however, there is uncertainty regarding costs related to the solar panels, storage tanks, furnace and installation. It is possible the upfront cost would be high, but homeowners would pay off the system over time if they no longer relied on city electricity or natural gas.
It is unknown when the hydrogen solar panels will be available on the market.
