jamonit the original debate was about hydrogen locking up vast amounts of water, can you imagine billions of litres locked up in hydrogen??

It will have the same effect as building dams, that is the problem in some countries like India, they built dams and now have no rainfall to fill them......they reduced the evaporation surface area, leading to less rainfall....causing drought.

The same will happen with hydrogen, do you not think they had so called experts when the Dams were built???

it has also been proved that so called experts get it wrong most of the time and the truth is it is trial and error.

A couple of interesting points about hydrogen as a fuel.
Leakage of hydrogen into the atmosphere does not necessarily lead to its loss into space in spite of its lightness. Most of it would probably react with the ozone layer to form water. Unfortunately this would lead to ozone depletion particularly at the poles and aggravate the existing problems arising from the (mainly) former use of cfc's.


On another, slightly pedantic, point - It is possible to have a higher oxide of hydrogen than water, i.e. hydrogen peroxide, which can be considered as a further oxidation of water. However the process of this further oxidation is endothermic and only releases energy when the process is reversed. In spite of its energy creating potential (e.g. being used as a constituent of rocket fuel and for other nefarious purposes) it is not a material which lends itself safely to commercial use in concentrated form.

The differences in energy levels associated with multiple oxidation (or valence) states of relatively easily handled metallic elements are a more promising avenue for energy storage, vanadium oxides being a prime example of that.

Out of curiosity, I had a look for this iron/water reaction. Found this link.
Note that it is dated 2002.
I have no idea what the overall energy efficiency is, but suspect this technology has been made redundant by advances in battery/super capacitor technology coupled with renewable energy supply.

I'll have a juke jamonit

Bought a few more on a whim which is probably as good a reason as any with these types of share

they already use rust to produce hydrogen...

[dlg3] 16/5/2018 11:38

Japanese engineers claimed this week to have found a way to produce hydrogen fuel on board cars by accelerating a process similar to rusting.

You don't oxidise water ??? who said that, only you, read..

There are plenty of these very slow planet killers: sooner or later humans will either get in place very slow-working policies that control them, find resources on asteroids comets etc to replace them, or fail, perhaps because we haven't the capacity for long-term thinking and enlightened self-interest. At the moment we seem only to be intent on "growing the economy" i.e. increase our pace of using things up. Not a good outlook.

jamonit most things contain moisture so when you oxidise anything you get hydrogen, amongst other things. But as you loose that hydrogen into space you use up your water supply. The sun is already doing its best to dry out the Earth, never mind man adding to it.

perhaps you should do a little reading moons and planets by W. Hartmann would be a start.

My brain had fused, thank you for restarting it.

the world is already short of water, rainfall happens because of precipitation, they have not figured it out yet !!! that if you lock up masses of water you reduce the surface area, so that precipitation is not sufficient and you get less rainfall, leading to drought, then death, be it India Africa or Europe...

All those ice burgs that are melting, they will need them, then when the next ice age comes and billions of gallons of water get locked up in the artic,s then everywhere near to the equator becomes a dead land..... not a pretty picture.

the other thing is why would you go to the length of using electricity to convert water to hydrogen?? to only use that energy, each time you convert there is a loss, why not just store the energy and have no loss, it does not make any sense, to build hydrogen plants at great expense then to build expensive fuel cells to burn it, but you also have to have somewhere to store it without it leaking into the atmosphere..

But if you are happy to bang on with hydrogen then so be it...

Me I prefer the simple route, produce electricity then use it, sounds simple, that is because it is!!!

Atmospheric escape is the loss of planetary atmospheric gases to the outer space. Our atmosphere exists because of gravity. Lighter gasses, like hydrogen (the lightest) can escape from Earth's gravity and therefore move out into space.

Did you know that??

They think the same thing happened on Mars, but that was not human induced...

[dlg3] 15/5/2018 18:14

gspanner yes can you imagine turning all the water on the Earth into hydrogen only to see it disappear into space, hydrogen is a route to suicide..

[gspanner] 15/5/2018 16:25

Dig3

OT

Presumably you have seen hydrogen cell electric vehicles? Solve many of these problems, only issue (IMO) is fuel energy density requiring H2 at 700 bar to be liquid; but can be filled up from petrol pump. Now being stationed in shell garages alongside conventional fuel. Argument has always been infrastructure required for H2, but IMO worse for pure EVs. Will see first in fleet urban vehicles.

Look at ITM website for more info.

Cushman envisions gas stations converting to be battery fueling stations, perhaps one pump at a time as demand ramps up. Stations could use their existing infrastructure and transportation chain for the electrolyte fluid.

“The petroleum companies don’t want to see all their gas stations left by the wayside,” Cushman says. “We can pump our electrolytes through the existing pipelines. There’s nothing hazardous; it’s all biodegradable.”;
