Olympic Athlete Runs In A Bubble Filled With Hyundai Nexo’s Exhaust Flow

Eager to show the world just how clean its hydrogen-powered Nexo SUV is, Hyundai recently recruited the help of Olympic athlete and brand ambassador Mireia Belmonte.

As the Nexo uses a hydrogen fuel cell, it emits only water and 99.9 per cent filtered oxygen, so the South Korean automaker’s Spanish division decided to demonstrate this by setting up a sealed air bubble connected to the Nexo’s exhaust and had Belmonte run on a treadmill in the bubble. It makes for pretty entertaining viewing, especially when you consider what would happen if you tried this with a petrol or diesel-powered vehicle.

The hydrogen system of the Nexo works much like other similar powertrains. There are a trio of hydrogen tanks that feed into fuel cell stacks where at the anode, the particles are broken down into electrons and protons. These electrons produce a current that supplies power to a battery which drives an electric motor at the front wheels. The leftover protons are sent through a membrane where they react with electrons and collected oxygen to create water which exits through the exhaust.

While the technology has a lot of potential, FCVs have failed to take off the way many would have expected a decade or so ago. This could be attributed both on car manufacturers throwing their hats into the EV race rather than the hydrogen vehicle market, as well as the costs that are still prohibitive.

    Cool gimmick, now I feel like we’ll see something snarky from Elon/Tesla in response.

    Good to see another fuel cell vehicle in the mix. Hopefully the technology and infrastructure can advance faster.

  • GobbleUp

    Dumb gimmick. And irresponsible.

      “it emits only water and 99.9 per cent filtered oxygen”

      How do you figure this comes under the premise of being irresponsible.

  • Callanish

    The Hydrogen Fuel cell vehicle is a great idea in principle that will never become mainstream in reality. The infrastructure for it has barely moved forward in 10 years. I remember looking up a hydrogen fueling station for my location 10 years ago and there was only 1 available. Today, still 1.

      “Japan announced Wednesday that energy ministers or delegates from 30 countries are supporting a plan to develop hydrogen energy for transportation.

      The 30 countries reportedly agreed to calls to increase production of hydrogen-powered mobility systems, such as fuel cell vehicles, trucks, buses, trains or ships. The goal is to make 10 million such systems available worldwide over the next 10 years.”

      And most importantly China wants to buy 1 million FCVs in this next decade. And they plan to make at least 10,000 more fuel cell stations in the next decade as well.

        I think H has hope with ships on the sea (plenty of fuel under them and plenty of fuel to convert if they’re shipping petroleum/gas of certain types.), maybe airships, but that’s about it.

    • Giuseppe Cochi

      you are correct that it has not moved forward and that hydrogen filling stations are rare, but that is changing, ENI in Italy are setting up hydrogen fuel refilling stations in conjunction with Toyota, the hydrogen will be produced at the stations using renewble sources, and that also illuminates the distribution problem as of

  • pcurve

    next time, full throttle dyno please.

  • brn

    So the same thing could have been done with a 2000 Ford Focus FCV?

    No wait, what about the 1966 GM Electrovan? Um yea, not new.

  • ok, we get it, you vape.

  • Porkopolis

    Water vapor is a far more abundant and efficient greenhouse “gas” than carbon dioxide. These things create tons of the stuff. Talk about global warming…
