Researchers Use Rust and Water to Store Solar Energy as Hydrogen

Researchers Use Rust and Water to Store Solar Energy as Hydrogen

Scientists at EPFL have come up with an inexpensive way to store solar energy as hydrogen. It's a concept that has been around for a while; a tandem cell consisting of a dye-sensitized solar cell coupled with an oxide-based semiconductor to convert solar energy into hydrogen, which can then be stored. That way the energy can be used either day or night instead of the "use it or lose it" set up of current solar panels. So far, the most successful iteration of a device like this was able to attain an efficiency of 12.4 percent, but the materials used were expensive and would cost about $10,000 to cover a 10 square centimeter surface. The EPFL researchers, led by Kevin Sivula, wanted to make something that could actually be produced and so they limited themselves to inexpensive materials and to production techniques that could easily be scaled up. According to the team, the m...
