I can't find the exact figures, as it depends on battery range and battery tech. One study I've seen found a battery truck would weigh over 5000kg more than a hydrogen-electric version.
I've also seen figures of double the weight for a Li-Ion battery EV compared to HEV at ranges above 300 miles.
It is technically challenging, I don't disagree, but it has high energy density by weight. It also, of course, has lots of other applications. Steel manufacture being one.
But to be honest, even if it never eventuates and we get carbon neutral biofuels, I'll be happy. Anything is better than what we're doing right now.
Price will come down with scale. Currently hydrogen is only produced at a very small scale. As production increases, price will drop. Simple really.
Freezing pumps is a problem I'm certain will be solved. In its infancy, EV charging stations were slow. Look how far the technology has come in a short number of years. As uptake increases and infrastructure is built, I am certain these problems will be overcome.
Yes, as I said above, this is true because a) hydrogen doesn't currently have the scale to bring the cost down, and b) is more suitable for large vehicles anyway. It's failure to be a viable consumer option doesn't mean it wouldn't work in mass freight transport.
There are problems with these articles, and it almost always comes down to scale. There currently isn't the scale and infrastructure to bring the cost of hydrogen to make it cost effective compared to pure electric. With time that could change if there is a will to do so.
But regardless, as I mentioned in my other comment, hydrogen has a much better use case in large scale transport. Trains and ships, for example, where volume isn't a problem and where the weight of batteries becomes untenable. This is, I think, where hydrogen will be viable.
There seems to be a general push against hydrogen electric transport recently. I agree that it isn't suitable for small-scale transport, such as cars or even busses, but I do think there is a use-case for large transport.
Ultimately the problem comes how do we get the electricity from the generator to the vehicle where it needs to be. Obviously batteries are more efficient, but they come with their own problems. They weigh a lot, which damages infrastructure, they require rare metals, they have a maximum capacity per unit weight.
Of course they have advantages, but I think as the vehicle gets larger, and the charging time requirements drastically increase, I think there comes a point where hydrogen electric systems are worth looking at. Trains and shipping being the main ones, and potentially trucks.
Of course, if the hydrogen is not generated cleanly then it's moot, but the same is true for pure electric systems as well.
Ultimately, I would like to see renewable generation that turns excess power into hydrogen for a train and coastal shipping fleet.
Sounds great, breaking up the monopoly. Of course, they products should have to meet our current regulations. If that isn't a part of this it could just lead to Leaky Homes 2: Electric Boogaloo
Oh I have no doubt about that. And I've flatted in Dunedin, so I know what those old shitbox houses can be like. I think the point of all this is that it's dated and needs work, but isn't unlivable.
Of Luxon had come out and said "my bad, I didn't really think about it as it's one of the entitlements of the job, but now that it's been brought up you're right I don't need the allowance. Why am I not staying in the Premier House? I just find my own apartment more comfortable is all", I honestly reckon it would have been a 24h story.
To me it sounds dated, like a 70s house or so. It was good enough for the last PM and her kid. I'm sure it's tired and a bit cold, but nothing worse than a lot of renters put up with.
Implant babies in women.
Allow more immigrants.
Kill older people or at least urge them to kill themselves to solve this crisis that’s going to destroy their country.
Or encourage families to have kids through incentives? Or increase wages and lower the cost of child care so couples can afford it now? Or combat social norms that women are supposed to stay at home? There are lots of ideas that aren't "force women to have babies" and "kill all old people". I can only assume you are being intentionally obtuse, because I can't imagine you are so stupid to think that these are the only options.
Then again I completely and utterly reject your insane alarmism over this issue. I don’t think this is some massive problem that’s going to destroy the country or GASP!!! make us like Japan. Imagine New Zealand being like Japan. Can anybody imagine something so horrible!!!
You do realize it's not just me, but lots of countries and scientists around the world pointing to the problems that can arise from a rapidly aging population, right? Take Korea, for example. They have the worlds lowest birth rate, and this year it dropped even lower to 0.78 children per woman. By 2067, it is predicted that 46% of the population will be over 65. Can you really not grasp how this will have huge ramifications for a society? When the working population is drastically lower than it is now? How will this affect the economy? Who will look after all the retired people when they need care? And so on and so on. It's not a hard concept, despite you doing your damnedest to channel a moron.
Honestly your alarmism is unhinged.
What alarmism? I simply pointed out it will be a problem if it continues. I didn't shout "WE NEED TO DO SOMETHING ABOUT IT NOW!" or anything, did I? I pointed out it is already starting to be a problem in other countries, which is true, and you started going on about forcing pregnancies and other stupid shit.
By the way, most countries where the birth rate is significantly below replacement level have started trying to combat this, usually with financial incentives for having children. Some, such as Korea, have spent billions on this. If it isn't a problem, why waste all that money?
