Crazy scientists think weird and gloopy hydrogen ‘toothpaste’ is the fuel of the future


While battery-electric vehicles steal much of the limelight in low-emission driving at the moment, hydrogen is still under study as the fuel of the future. And who would have thought it would look like weird gray mud.

Some believe that hydrogen is the best long-term option for low-emission vehicles because it is very energy dense and can refuel a vehicle in minutes – much like a conventional gasoline car.

However, that comes with a few caveats. Hydrogen is very difficult to store, and the infrastructure of fuel cell electric vehicles is rarer than a nine-coil note.

But some crazy scientists have thought outside the box and found a solution. It looks like a gloopy, dirty old toothpaste that was scraped into a U-bend. On the plus side, it’s called POWERPASTE, which is potent and cool. It’s not at all weird.
