Hydrogen powered Jeep.

Gundog · Guru

In my view this is another grand utopia idea lacking practicability, yes it meets the zero emissions ideal, looking at the picture of the of what appears to be 3 hydrogen fuel cells in the rear of the vehicle, it takes up a lot of room.

What would be the cost to establish a comparable network of refilling stations or swap cylinder facilities, could you honestly believe that every existing service station would have a Hydrogen pump or swap and go facility, do you consider the small outback private owned facility could afford the investment and then generate a reasonable ROI to make viable.

The other hurdle to green hygrogen is cost per kg to manufacture, hence the Twiggy Forest Qld Green Hydrogen project is sort of on hold at the moment, the so called cheapest form of power, Wind and Solar appears to be too expensive for the end user to proceed yet.

Why bugger up something that works for a fantacy.

Hydrogen powered ICE will never be a goer IMO. The one in the article has no fuel cells. They are hydrogen tanks.
But this bloke reckons hydrogen powered electric busses is the go.
He will produce hydrogen for his own use to power his fleet of busses.

I suggest that hydrogen will be readily available as the interstate semis all convert to hydrogen/electric.
Cheers,

They will all be out of business before they can say B-R-I-N-G B-A-C-K D-I-E-S-E-L.

Talking about this, a very large hydrogen fuel plant has been announced for building outside of Whyalla in SA.

Be interesting to see the uses that fuel is put to, as long as the plant gets beyond the drawing board stage!

That is what they said about horses, but this change will happen much quicker.

I would not be surprised if all the technology for electric/hydrogen or whatever forms of propulsion is not already available.

Imagine if it was brought in tomorrow. Most of the world's economies which are based on oil, fossil fuels etc would collapse, major oil companies would be bankrupt and we would all be fighting each other.

I think all this technology will just be fazed in over a few decades to prevent total chaos.

I invested in Twiggy some time ago at 14c.
Fortescue went up 2% again today I just noticed on my share portfolio on the back of the budget handout.
A mate of mine in heavy machinery/transport tells me to have Hydrogen power in a truck you would need a a tanker attached on the back the same size as an oil tanker to have enough fuel for an interstate trip using Hydrogen and therefore not feasible?
We will find out I guess when they build one.
I invested in Twiggy (married a local girl) because he was to get a billion $ state govt handout to install hydrogen stations all the way up the highway in NSW from Melbourne to Brisbane.
I suppose he is savvy enough to know that a truck fueled on Hydrogen would need to make several refuelllng stops??

We will know in time I guess, I am no expert but that is what some in the know have mentioned in relation to Hydrogen.

Some of the more learned on here would have more to offer than my humble self.....

Also, I have pondered, if they produce hydrogen from water, what is the composition of the water after it has been treated?? Is it still water??

Hey?

If climate change is warming the planet and rising the sea levels.

How much has Bondi beach chewed up on the beach with the "reported" rising sea levels in the last five to ten years?

If you take the hydrogen out of water there is pure oxygen left. Then when you use the hydrogen, you get the water back, plus lots of power.

This Daimler one from January claims a range of 1,000km.

OK thanks.

I knew there would be someone on here with the smarts to answer that !!

The other thing I find confusing is that the sea levels only appear to be rising where there are court cases suing the government for inaction on climate change but my friends on the coast tell me the water levels all seem to be the same on their wharves.

Why is it so?

A websearch for sea level rise measurement in Australia gives this from one source:

Around Australia, sea levels are rising at or above this global average. Tide gauges indicate the rate of rise in northern Australia since the early 1990s is around 4-6mm/yr. Along the south-east coast of Australia, its about 2-4mm/yr. Rates of sea-level rise are not uniform around Australia because of local effects like ocean circulation and tidal processes.

Here is a link to the UNSW article:
www.unsw.edu.au/newsroom/news/2024/01/how-rising-sea-levels-will-affect-our-coastal-cities-and-towns~:text=Around%20Australia%2C%20sea%20levels%20are,about%202%E2%80%934mm%2Fyr.

Plenty of information about world wide affects too, if one wants to have a quick search.

Edit: some hyphens and quotation marks were not added in my first copy and paste. Hopefully they are in place now. Order of magnitude difference in rate of rise otherwise.

Climate Change: Global Sea Level | NOAA Climate.gov

The global mean water level in the ocean rose by 0.14 inches (3.6 millimeters) per year from 20062015, which was 2.5 times the average rate of 0.06 inches (1.4 millimeters) per year throughout most of the twentieth century. By the end of the century, global mean sea level is likely to rise at least one foot (0.3 meters) above 2000 levels, even if greenhouse gas emissions follow a relatively low pathway in coming decades.

In some ocean basins, sea level has risen as much as 6-8 inches (15-20 centimeters) since the start of the satellite record. Regional differences exist because of natural variability in the strength of winds and ocean currents, which influence how much and where the deeper layers of the ocean store heat.
