Sweet hydrogen: how sugar could help satisfy the world’s energy needs

SugarThe Guardian – Hydrogen makes an extraordinarily efficient and clean fuel. Three times as energy-efficient as petrol, Nasa used it to power its space shuttles. It can be used to generate electricity and only produces water as a byproduct.

And yet, scientists are struggling to scale up hydrogen production. Ironically, given hydrogen’s green potential, the cheapest and most viable sources are hydrocarbon-based compounds such as natural gas. But liberating hydrogen from fossil fuels creates carbon emissions that outweigh any environmental advantages.
