    Hydrogen is plentiful on Earth, but it's not easy to unlock from its geological and biological sources. Many of the current synthesis strategies are expensive and energy-intensive, negating hydrogen's environmental benefits.
    But scientists at Cardiff have recently found a way to derive hydrogen gas from fescue grass with a new strategy called photoreforming, or photocatalysis. During photoreforming, sunlight triggers a catalyst, setting in motion a chemical reaction that converts cellulose and water into hydrogen.
    Researchers tested three relatively cheap metal-based catalysts -- palladium, gold and nickel -- and found success with all three.
    Researchers believe it's the first time lawn grass has been used to turn cellulose into hydrogen.
