Scientists in Belgium have invented a solar panel that produces hydrogen as a source of fuel to heat homes. Using moisture in the atmosphere, the solar panel converts sunlight into hydrogen gas, producing about 250 liters of gas every day.

The team of scientists, lead by Professor Johan Martens, have been developing their hydrogen solar panel for the past 10 years. When they first started, they were only able to produce small quantities of hydrogen gas, but now the gas bubbles are visible the moment they roll the panel out under the sun.

“It’s actually a unique combination of physics and chemistry,” Martens explained. “Over an entire year, the panel produces an average of 250 liters per day, which is a world record.”

According to CleanTechnica, Martens estimates that 20 solar panels could provide enough energy and electricity to heat up a home and still have some to spare for the following year.

The team is still not ready to build the panels for commercial use, but they are getting ready for a trial run at a home in Flanders. If the tests are successful, the researchers are planning to expand their trials to an entire neighborhood.

Being an extremely combustible gas, hydrogen can be dangerous if not handled correctly. While the general public may have some concerns about using hydrogen as a heating source, the Belgium-based scientists said it carries the same risks associated with natural gas. The hydrogen produced by the solar panels is stored in an oil tank that is installed near the home.

While this technology is certainly promising — and produces zero carbon emissions — the cost of the solar panels, storage tanks and furnace, plus installation, is a big unknown.

That said, the upfront cost may be high, but homeowners would pay off the system over time, especially if they no longer relied on city electricity or natural gas.

There is no word yet on when the hydrogen solar panels will be available on the market, but the scientists are very optimistic about the upper limits of this technology.
