We shouldn't individually own cars, parked in our driveways. We should share cars, parked in neighbourhoods. It would radically reduce the number of cars required.
Who else wants to have a go at this one?Imma weigh in here, for me it is simple - what's the most abundant element on earth?
Hydrogen can be produced, captured, transported, burnt for heat, converted to electricity...
The technology is not quite there and price to do this is high. But from a future perspective, that's my money for the solution to CC.
Burn water then....Hydrogen can be , burnt for heat,
Which part of this graph means we don't require a huge change?E.g. I agree with your point about car ownership, but realising such a vision requires holistic cultural change in the way our communities operate and our cities are built which takes longer than we have to address CC by your own reckoning. So while it should remain the target, what's the pathway? All our CC problems are like that - they necessitate huge change - but it's not a one step thing.
It takes energy to create and store hydrogen and that has to come from somewhere and if you think that somewhere is more hydrogen then you just don't get physics.Imma weigh in here, for me it is simple - what's the most abundant element on earth?

I've tried but it never works.Burn water then....
What about "Fire Water"?I've tried but it never works.
Yes. Your point?It takes energy to create and store hydrogen and that has to come from somewhere and if you think that somewhere is more hydrogen then you just don't get physics.
You said this:Yes. Your point?
The same logic can be applied to Hydrogen.Until and unless the power in this country is dominated by renewable sources, EV is kinda a waste of time.
Yeah absolutely agree, but the ability to store the energy created as a gas (possibly liquid) is a far better option that batteries IMO.You said this:

I guess you don't realise that it takes enormous amounts of energy to liquefy hydrogen, nearly 4 kiloWatt hours per kg. That's around 15% of the energy you get back in ideal conditions which we don't have(losses from heat, friction etc). Pumped hydro can give you over 90% return and batteries over 95. Hydrogen is part of the solution but because of the wasted energy processing it, it isn't the solution.Yeah absolutely agree, but the ability to store the energy created as a gas (possibly liquid) is a far better option that batteries IMO.
Fuel cells may possibly work in some very niche applications where their terrible efficiency and high cost isn’t a problem. But no way they’ll be a mainstream solution.Yeah absolutely agree, but the ability to store the energy created as a gas (possibly liquid) is a far better option that batteries IMO.
then you just don't get physics.
R U OK mate? Or are you going through a tough time personally that's affecting your attitude?I guess you don't realise
The efficiency is certainly not ideal.Fuel cells may possibly work in some very niche applications where their terrible efficiency and high cost isn’t a problem. But no way they’ll be a mainstream solution.
Hydrogen is not a fuel. It’s a battery. A very inefficient and expensive battery...
Look up and read AEMOs ISP. It’s all in thereThe efficiency is certainly not ideal.
I think the interesting comparison would be the amount of battery storage required for load balancing in a 100% renewable environment.
Or make diamonds out of CO2 with a big ass microwave.Nuclear is the answer. That way at night you can open up the reactor instead of using lights!
