Chat/Discussion Kind of like a VW club online - you can sit in our virtual pub and talk about whatever you want to. All opinions are valid, but please no insulting (other than to our intelligence,) abusive or libellous posts. Please feel free to post your opinion on any given subject, but also be aware that others have the equal right to disagree with you - and some will certainly tell you so. No 'For Sale' or 'Want To Buy' ads, plugs for your business, links to 'for sale' ads or Ebay links to your (or your mate's) auction (please use the VZi 'Classifieds' section) - this also includes thinly veiled "What's my car worth?" threads too (please use the 'Dude! What's My Car Worth?' forum) - and please don't use just to post links to other VW forums or websites - we are aware that other sites exist (obviously), but blatant 'plugs' (poaching) will simply be deleted.

Question hydrogen fuel cell cars… better than electric?

Hydrogen Car Emissions… alternate car tech…

The hydrogen fuel cell-powered SUV only emits water and 99.9 percent filtered oxygen.

One of Hyundai's latest eco-friendly cars, the Nexo, is a hydrogen fuel cell-powered SUV that the company claims only emits water and oxygen. To prove this fact, Hyundai España's YouTube page has posted a video where Olympic swimmer and brand ambassador Mireia Belmonte runs in a bubble filled with the car's emissions.

With the promise of such an environmentally friendly transportation option, we wonder why hasn't the vehicle's adoption been guaranteed yet? Well, it turns out it is hampered by the lack of proper fuel cell infrastructure.

While we wait for that infrastructure to take place, we might as well enjoy this well-shot well-illustrated video. However, be wary of trying this at home!

Despite the fact that Hyundai claims the vehicle only emits water and 99.9 percent filtered oxygen, the firm still employed the services of the Spanish National Centre on Hydrogen and a sports medical center to make sure the video's process was safe.

Brilliant,

Buy one, cut down all the trees - and you have still broken even

No!
It's all about efficiency, make electric, use that to make chill and liquefy hydrogen, transport and store at filling station then pump into car.

Or just use the electricity to charge the cars battery.

Battery cars have zero emmisions not even water!

The following explains it all.

I'm thinking of twinning myself with trenchfoot and using him as my carbon offset.

Apparently methane is a more damaging greenhouse gas, so when I break wind , if I set light to it does that make me a little more environmentally friendly?

what about the production of the batteries? i read that electric vehicles can generate more carbon emissions over their lifecycle,from procurement of raw materials to manufacturing, use and recycling, than petrol or diesel cars.

Well that's assuming that the electricity is produced from wave or wind generation. And also ignoring the production of the car (either electric or ICE).

You're actually better off running an old car, yes it emits more co2, but not as much as building a new one does. So all of us here are actually doing our bit by running old cars

I keep banging on about this but but something most people do not appreciate is every gallon of fossil fuel you put in your tank has used electricity in it's production. A very large amount of electricity. It's around 6-7 Kwh per liter.

A full electric car will travel around 30 - 35 miles on that much power.

So if you don't refine oil there will be plenty of power to charge peoples transport.

The reports about life time CO2 are all 1/ flawed and make poor assumptions. and 2/ Funded by oil companies.

Heres some figures on lifetime emmisions based on different energy mixes around Europe, even in the places burning lots of coal they are still around 25% better in terms of lifetime emmisions.
