The use of hydrogen as a fuel and energy storage medium every bit interested scientists for decades, but physics isn't on our side. Generating hydrogen from water requires a lot of power and expensive materials, but researchers from Washington State Academy may have developed a method that could make information technology a viable way to shop energy cheaply and efficiently.

Many of the technologies we await toward as part of a renewable energy economy are less consistent than traditional means. For case, solar power produces a lot of energy during the solar day and none at night. It's the same story with wind ability — information technology might provide more power than needed when it's gusty out, just none on a calm day. You lot need some way to store backlog free energy for subsequently use, and bombardment technology comes with its own complications. If you can generate hydrogen, it's an extremely efficient way to store free energy. Just pump it into a fuel prison cell, and you go water and energy. In improver to industrial storage, some vehicles could also be powered by hydrogen fuel cells.

The issue with using hydrogen is that you demand a lot of ability to split a h2o molecule (the most common source of hydrogen atoms), and the catalysts needed are expensive. Almost methods utilize either platinum or ruthenium, and they must be replaced often as they degrade. Every bit described in a newly published study, the Washington State team used inexpensive and plentiful nickel and atomic number 26 to brand a water-splitting catalyst.

The squad calls its material a "porous nanofoam." It's a bit like a metallic sponge with microscopic holes and tunnels that requite it a very large total surface area. That's primal to its power to catalyze the germination of hydrogen and oxygen from water. In testing, the team plant this cloth was fifty-fifty more constructive in generating hydrogen than the more expensive catalysts fabricated from precious metal. As for stability, the team reports information technology showed no driblet in functionality later on a 12-hour run time.

Virtually elements of this process are the same nosotros currently apply to generate hydrogen, so it'south believable the nanofoam could be substituted for other catalysts at industrial scale with few changes. However, the Washington State University study only tested the material in a laboratory setting. More inquiry is needed to see how the nanofoam goad might work at industrial scale. Until so, don't toss your lithium-ion batteries in the trash.
