Will Ev's Become The Betamax ?

[youngmafbog]

JCB have created a hydrogen digger. A new ICE not an old one tinkered about with but one that doesn't give out nitrogen.

I've raised similar threads on here over the years but am usually derided by the usual. But for me hydrogen is the way to go, at least for the immediate future.

Thoughts?

The ultimate climate friendly fuel.

In the short to medium term they can be applied where they work best. Electric may remain the best option for vehicles used for intermittent short journeys. Heavy use, high demand will probably be the main hydrogen power users until other things come onstream. Let's face it. Twenty years ago they were talking about small nuclear engines powering vehicles, and technology is moving so fast we can't really predict with any certainty.

It'll be slow in coming, too much loot to be made from the current climate emergency for a while yet.

Imagine trying to spin tax, duty and levies on a non-polluting fuel.

For quite a while there has been a hydrogen fuelled car and a re-fuelling point in Leeds.

Logically the reverse would be needed , tax breaks. Maybe reductions in taxes on purchase and fuel used.

if you always do what you've always done, you always get what you always got.
I don't know the answer to your Q as i know barely anything about hydrogen power. I hope that someone (more intelligent than me) is working on it :)

"Will Ev's Become The Betamax ?" - interesting, quite possibly but we'd need a way of producing hydrogen without lecky. Currently it's a waste of energy to use the electricity to spilt hydrogen away from oxygen, you may as well use it directly. So unless some genius comes up with a much more efficient way of getting hydrogen un stuck I'd say direct use of electricity is going to be the better use of that energy.

danny: "the ultimate climate friendly fuel." - how do you think hydrogen is acquired?

//Today, hydrogen fuel can be produced through several methods. The most common methods today are natural gas reforming (a thermal process), and electrolysis. Other methods include solar-driven and biological processes.//

[ToraToraTora]

danny: "The most common methods today are natural gas reforming (a thermal process), and electrolysis." - and how or those powered?

[ToraToraTora]

I stand by what I said we need a low energy low cost way of un sticking H or it ain't viable on a large scale.

[ToraToraTora]

great, if they are the main way and are viable, fill yer boots, I'm on board. I just worry the same sort of people are lauding that are the ones that claim Drax is in anyway climate friendly.

[ToraToraTora]

this would be good if they could increase the efficency of production:
https://www.energy.gov/eere/fuelcells/hydrogen-production-photobiological
" Some of the major challenges of this pathway include a very low hydrogen production rate and low solar-to-hydrogen efficiency, making it a commercially unviable pathway for hydrogen production at this time"

[THECORBYLOON]

There are various "colours" of hydrogen, indicating the method of production.

There is also "gold" hydrogen, which is naturally occurring hydrogen in the earth's crust.

[douglas9401]

dannyk13, your 9:50 post kinda backs mine up I'd say.

[youngmafbog]

//we'd need a way of producing hydrogen without lecky.//

Why? As per the article we can have 'free' electricity from very clean means i.e. Solar and Wind. At night the electricity from these cannot be saved so is already 'wasted' so generate the hydrogen at night. The other alternative suggested is that the Arab States invest in Solar and again use the surplus to generate the hydrogen. The liquid hydrogen (or Ammonia) could then be shipped locally or it could simply be piped in the same way we do with Natural Gas currently.

[youngmafbog]

Of course, if someone comes up with a capacitor type 'battery' that charges quickly and is not as heavy and doesnt use the horrid chemicals currently being used then all bets are off again. But at present that doesnt look likely in the immediate/mid term future.

I'm hoping that practical fusion will be developed.
